1 Eclipse Laser Marking System General Arrangment System Overview The Telesis 100W Eclipse Nd:YAG laser is a high-powered, lamp-pumped, Q-switched, galvo-steered laser designed for marking applications. Eclipse lasers deliver a 1064 nm laser beam which is excellent for deep engraving into metals and for high speed marking of plastics with a high carbon content. The Eclipse laser offers these advantages: Rugged industrial design with field-proven lamp-pumped technology 100W average power; greater than 200KW peak power Broadest beam width and greatest depth of focus allow easy setup and fast material processing Exceptional beam quality works with the broadest range of material applications Off-the-shelf consumable components available from several after market sources Three-point rugged INVAR bar-based rail construction for precise optical alignment Ceramic pumping chamber for performance and long life Umbilical can be detached from rear of controller for easy integration of rail Long-life lamps; changes do not require cavity re-alignment Simple and easy to maintain in a factory environment System Configuration Thoughtful engineering allows major components to be quickly replaced and damaged components returned to Telesis for repair or exchange. Integration is made easy with a detachable umbilical. The rugged industrial unit allows for routine consumables to be replaced without the need for realignment of the laser cavity or optics. Depending on the level of integration, lamp replacement can be completed in less than 20 minutes. The 100W Eclipse Nd:YAG laser system basic package consists of the following components.

2 Eclipse Dimensions and Mounting Details Laser Rail The laser rail assembly consists of a laser pumping chamber (laser engine/laser resonator/laser head assembly) and is attached to the beam steering galvanometer package. The laser rail cover serves as a sealed lightweight dust cover and encloses the straight optical rail. This configuration provides easy maintenance, long term optical alignment and performance in the most demanding industrial environments. All mechanical and optic components are mounted on a three point INVAR rail that precludes the need for routine adjustment of optical components, and ensures increased power and thermal stability. Inside the sealed laser resonator pumping chamber is an Nd:YAG rod shaped crystal mounted in close proximity to a bright white krypton arc lamp. To complete the generation of laser energy and to precisely control the laser output, other devices are mounted on the INVAR rail. These essential devices include the front and rear optics, an acoustical/optical modulator (Q-switch), the electromechanical safety shutter, the beam expander (collimator), and a red light positioning diode. The Eclipse produces a continuous wave Nd:YAG laser beam. It uses an acoustical/optical modulator (AOM), or Q-switch, to produce a pulsed laser output. The Q-switch alternately blocks and unblocks the reflective path between the optical mirrors. The Eclipse also incorporates a red light positioning diode. This is a co-focal, visible red beam that passes through the same optics that the 1064 nm marking beam travels. This provides a safe and convenient aid to the user for one-off part program setup. The visible red light maybe viewed on the work surface without the need for protective safety goggles. The electro-mechanical safety shutter is solenoid rated for greater than one million cycles. The Eclipse design uses a combination safety shutter and front mirror mount for space saving and ease of alignment. Under power, the safety shutter allows laser energy to pass through the galvanometer steering mirrors. If the shutter is closed, or power removed from the system the spring-loaded barrel will rotate to inhibit the beam.

3 Galvanometer Optical Scanners Each galvo assembly has two optic scanning galvanometers, one each for controlling X-axis beam positioning and Y-axis beam positioning. Galvanometer scanners are computer-controlled highperformance precision closed-loop rotary motors. They consist of a motor section based on moving magnet technology and a highprecision closed-loop position detector. Attached to each motor shaft is an optically coated mirror assembly to deflect the beam. Each optically coated mirror assembly is factory balanced and bonded, then each combination of mirror and motor assembly are electronically equalized in the control circuitry. Galvanometer Optical Scanners Flat Field Lens, Final Objective Lens, (F-Theta Lens) The final object lens is key to the marking performance of the system. This is the final coated optical lens that the beam will pass through before it strikes the marking target. The final objective lens is sometimes called the F-Theta Lens because the lens is optically corrected to provide an image height that is proportional to the scan angle (Theta), not the tangent of that angle, as is usually the case with traditional optical lenses. This lens is also called a flat field lens because when the beam is focused, the focus lies in a plane perpendicular to the optical axis of the lens. The following chart outlines the available lenses, their part numbers, the mounting kit (bezel) part numbers, and the resulting image field provided by the lens (in millimeters and inches). Lens Lens Part No. Mount. Kit Part No. Typical Image Field (mm) Typical Image Field (in) 100 mm x x mm x x mm x x mm x x mm x x mm x x mm x x To protect the final objective lens from dust and debris, a clear protective cover is inserted between the work area and the lens. The lens and protective cover is held in place by a threaded adapter ring called a bezel (mounting kit). The bezel threads directly into the machined galvo block. The lens and protective cover can be replaced in less than five (5) minutes. A properly maintained lens will remain functional indefinitely. Periodically, as a standard practice, the lens should be cleaned using an approved optical lens cleaner and soft optical tissue. Marking Characteristics Spot Size (line width). The laser spot size can be thought of as the line width of the image being marked. For all practical purposes, the laser-created text (or any machine-readable code) can be programmed to mark or engrave smaller than can be seen without magnification. In the opposite extreme, it can be marked so large as to cover the entire marking field. In all cases, laser spot size is dependent on a variety of factors including lens selection, focus, and the material being marked. The resulting line width will be a combination of the previouslymentioned factors, as well as the beam diameter at the work piece, the laser energy delivered to the material, and the heat affected zone (HAZ). The following chart is provided for reference only.

Simple laser parameters can be operator programmed to create depths ranging from simple surface discoloration (laser annealing), shallow laser etching or deep laser engraving. Marking depth is dependent on several factors including; material, lens type selected and other laser parameters. Please contact Telesis for the proper setting for your specific application. Doc.

4 Laser Controller/DI Water Cabinet Design to meet CDRH, CE standards, the Laser Controller/DI Water Cabinet contains the galvo power supplies, computer interface card, driver control circuits, fusing, and the closed-loop de-ionized water cooling system. The small profile cabinet is designed to slide into a workstation opening or placed directly under a workbench. The Laser Controller/DI Water Cabinet is remotely connected to the rail enclosure by a 3-meter (10-foot) umbilical. The umbilical is a combined multi-cable and hose assembly that carries power to the lamp, control voltages to the laser, and cooling, de-ionized water to the rail assembly. Laser Controller. The Laser Controller provides the energy to drive the krypton arc lamp (in the laser cavity of the laser rail enclosure) and to control the lasing process. The Laser Control Panel includes the system key switch, Laser Power Off, a manual safety shutter control, function indicators, and digital displays.

The internal de-ionized water system is a closed loop water to water heat exchanger system that transfers cooling water by way of a electric water pump from the DI Water Cabinet to the laser rail enclosure. Inside the laser rail the water is flows through the laser cavity cooling the laser rod and arc lamp assembly and through the modular AOM (Q-switch) to provide cooling to that optical device during lasing. The de-ionized cooling water is then returned through the umbilical to the DI Water Cabinet holding tank. The tank contains temperature sensors, di-restivity sensors, a de-ionizer filter cartridge, and particle filter water level sensors. It is important to note that the laser system should be shipped or stored dry with no water in the laser cavity or umbilical. This is to prevent water spots from forming on the reflective surfaces of the laser cavity and to ensure that water will not freeze in the lines or on the optics during cold weather. It is also important to note that the pump size on the DI Water Cabinet is designed with enough pressure to pump only to and from the laser rail enclosure.

5 System PC The laser system requires an IBM-compatible computer for running the Merlin II LS Laser Marking Software. The PC may be a desktop or a notebook computer and may be supplied by Telesis or by the customer. If the PC is supplied by Telesis, warranty for the computer, computer keyboard, monitor, and peripherals default to the original equipment manufacture. Galvo control cards are included, along with interconnect cabling. The laser software is installed and the entire unit is tested as a laser marking system. The minimum computer requirements are as follows: Pentium III with 128 Mb RAM 17-in. SVGA Color Monitor Multi-Gigabyte HDD CD ROM Drive 3.5-in. Floppy Disk Drive Windows 2000 or Windows XP Keyboard and Mouse One RS-232 Port, Two USB Ports Serial Two PCI Slots System Software Telesis powerful WIN32 Merlin II LS Laser Marking Software is a PC-based operating software package that comes standard with the Eclipse Laser Marking System. It is a graphical user interface that makes marking pattern design quick and easy. The WYSIWYG (what-you-see-is-what-you-get) interface provides a to-scale image of the pattern as it is created. Just click and drag for immediate adjustment to field size, location, or orientation. The Merlin II LS includes tools to create and edit text (at any angle), arc text, rectangles, circles, ellipses, and lines. Multiple fields may be grouped and saved as a block to form a logo. Existing DXF CAD files can also be imported for marking. Nonprintable fields can be created to clearly display a graphical representation of the part being marked. Communications Protocol Two types of host interface are available. Programmable Protocol is used where very simple one-way communications are required (such as with bar code scanners). Programmable Protocol provides no error checking or acknowledgment of transmitted data. Note that XON/XOFF Protocol applies even when Programmable Protocol is selected. The other type of interface is Extended Protocol. This protocol includes error checking and transmission acknowledgment. It should be used in applications where serial communication is a vital part of the marking operation.

6 System Setup Complete installation procedures are provided in the Eclipse Installation/Maintenance Manual. The following procedures are listed for reference only to provide a general overview of the installation process. 1. If you choose to mount the laser into a workstation that has not been designed by Telesis, consider these factors: Mount the laser rail in a horizontal plane. If you intend to mount the laser in any other orientation, please consult with Telesis Customer Service before proceeding. Mount the laser such that the laser rail cover can be easily removed for routine lamp changes. Ensure the installation location provides adequate clearance and ventilation. The umbilical cable requires a minimum bend radius of 18cm (7 in.) to avoid damage. 2. Equipment should remain powered down and in the OFF position until the mounting is complete. 3. Place the computer, monitor keyboard, and laser controller/di Water Cabinet in the desired location. Locate the Laser Controller/DI Water Cabinet as close as practical to the marking head. The standard umbilical length is 3 meters (10 feet). 4. Place the laser rail assembly in the mounting position taking care not to bend or kink the umbilical. 5. Mount the laser rail assembly by using three M6-1.0 bolts. Mounting bolts must not extend into the galvo block as to interfere with the internal components. a. Mounting holes are tapped for metric threads. Refer to the Dimensions and Mounting Details drawing for mounting bolt locations. Standard clearance holes (0.26 in.) for M bolts should be used. b. The leading edge of the mounting plate should be no greater than.875 in. (22.23 mm) from the first set of holes to allow clearance for the beam output lens. c. As viewed from front of laser in upright position, the center of the output beam is in. (308.36mm) forward of the first set of mounting holes and is in. (47.727mm) from the right mounting hole. d. A minimum distance of 14 in. (36 cm) should be allowed from the rear of the laser to allow for proper installation of the umbilical. 6. Ensure the Laser Controller power switch is OFF. 7. Connect the remaining cables as applicable. 8. Refer to the Eclipse Operation Supplement for proper startup procedure of the complete system. 9. Refer to the laser marking system Operation Manual for complete information on using the system software. General Mounting Procedures If you chose to integrate the laser into a workstation that has not been designed by Telesis, you should keep in mind the following engineering considerations when integrating your system. Design simple X-, Y-, and Z-axis adjustments. When designing a mounting fixture for the laser marking head, allow for simple three-axis adjustment to aid in horizontal, vertical, and lateral alignment of the laser marking head. Experience has shown that a minimum adjustment value of 12.7 mm (0.50 in.) is a prudent design consideration if the intent is to integrate the laser into workstation not designed by Telesis. Ensure the part and the part holding fixture are perpendicular to the final objective lens. When designing a work piece holding fixture, ensure the fixture is flat relative to the final objective lens of the galvo block assembly and square to the centerline of the laser marking field. Ensure the part is stable and will not move during marking. Laser marking is a non-contact marking method. Typically all that is needed is simple fixturing pockets or X-axis, Y-axis datum rails. Ensure the part width and length will fit in the marking area. Double check that all the parts to be marked will fit within the laser marking field. Ensure the marking area is not obstructed and can be targeted by the laser beam. Ensure the combined total height of the part and fixturing does not exceed the working clearance of the final objective lens selected. Care should be taken to ensure that the laser can be placed into focus on the part. The total combination of the part and fixturing height must not exceed the adjustment capability of the customer-supplied Z-axis. The working clearance is the distance between the bottom of the lens and the top of the part to be marked. See Marking Characteristics (Marking Field Size) for details on working clearances for the available lenses. Doc. No Rev. B 6 of 6
