Geltech Aspheric Lenses

High quality optical glass lenses Custom designs available Numerical aperture up to 0.83 Diameters from 0.250 mm to 25.0 mm Diffraction-limited performance Available in standard and custom housings For today s sophisticated and compact laser systems, aspheres are the most powerful lenses for managing laser light. In these systems, spherical aberration is the most prevalent performance detractor. It arises from the use of spherical surfaces and artificially limits focusing and collimating accuracy. Although it has been known for centuries that spherical geometry is not optimal for refracting light, the expense of fabricating nonspherical (aspheric) surfaces has inhibited their use. With the breakthrough of LightPath s glass molding technology, this optimal lens geometry has become a reality. Spherical vs Aspherical Lens Systems Spherical System Aspheric Lens Working Distance Center Thickness Aspheres provide elegant single-element simplicity Molded lenses are used in a variety of photonics products: barcode scanners, laser diode to fiber couplings, optical data storage, and medical lasers, to name a few. In many of these applications, the material of choice is optical glass because of its durability and performance stability over a wide environmental range. High power transmittance is also an added advantage. Laser Window Edge Thickness Clear Aperture Outer Diameter The benefits of glass molding technology become apparent when traditional methods of grinding and polishing become cost-prohibitive. The direct molding process eliminates the need for any grinding or polishing, offering aspheric lenses at practical prices for system designers. Molding is the most consistent and economical way to produce aspheres in large volumes. Small and lightweight, our aspheres collimate or focus light as a single element. This means less complex systems, fewer alignment requirements, less re-work and shorter assembly time. Our aspheres are molded; therefore the lenses have excellent piece-to-piece uniformity. They are made of glass, which is the most durable optical material available, capable of withstanding repeated cleaning and performing at specification despite extreme temperature and moisture variations. Guaranteed Performance LightPath s aspheric lenses are inspected and optically tested to ensure complete customer satisfaction. Visual cosmetic inspection is preformed on 100% of all lenses per MIL-PRF-13830B with a scratch/dig spec of 40/20. Other inspection criteria including 80/40 and 20/10 can be provided upon request. Typical Tolerances ± 0.015 mm ± 0.100 mm ± 1% ± 1% of EFL Optical performance is guaranteed by test methods utilizing 632.8 mm interferometer measuring transmitted RMS wavefront error listed in the individual lens specification. LightPath can also perform customized optical tests in order to screen for specific application criteria. www.lightpath.com 8

Optical Performance The primary optical specification is the root-mean-squared transmitted wavefront error (RMS WFE). It is measured on a phase shift interferometer at the wavelength of 632.8 nm. Most of our lenses are guaranteed to be diffraction limited, which means the RMS WFE < 0.070 λ at the design wavelength. Numerical Aperture Lens Holders Several of our catalog lenses are available pre-mounted in metal holders. Using our unique Mold-In-Place (MIP) technology, we can actually mold the lens directly inside of a steel holder, eliminating the need for adhesives in your package. We can epoxy our lenses into Stainless Steel or Kovar mounts so you can weld them directly into your system. Our molded aspheric lenses are available with numerical apertures ranging from 0.15 up to 0.83. Lower NAs are best when a large depth of focus is important or when you need nearly circular beams. Examples of applications that would use a low numerical aperture are bar code scanners, surveying instruments, and small weapons sights. High numerical aperture lenses are important when you need to focus light down to a small spot size or when you need the maximum light capture from a diode laser. High numerical aperture applications include data storage and industrial printing. Aspheric Optics Shapes and Sizes LightPath aspheric lenses are typically plano-convex or bi-convex, with diameters as large as 25 mm or as small as 0.250 mm. LightPath has the capability to dice the lenses to specified shapes for easier mounting. Custom Aspheres Our catalog details 53 standard types of available aspheric lenses.

Choosing Geltech the Aspheric Right Aspheric LensesLens For Diode Collimation One of the most common uses for aspheric lenses is in the collimation of edge emitting diode lasers. With over 35 standard lenses in LightPath s catalog to choose from, however, this can sometimes be a confusing task. The guide below will clear up some of the questions about choosing the best lens to use with a specific laser for a particular application. Due to the way that the laser cavity is constructed in edge emitting diode lasers, light is emitted in a diverging, elliptical geometry - so the divergence is typically specified in both the x and y axes separately. The axis with the larger divergence is called the fast axis and the axis with the smaller divergence is called the slow axis. When selecting a lens to collimate the laser, first consider the Numerical Aperture of the lens. If the application requires a high amount of the laser light to be coupled though the system, a lens with a high enough NA must be chosen. The NA of a lens is a measure of the maximum amount of divergence that the lens can capture from the laser. Ideally, a lens should be used that has an NA higher than the NA of the laser s fast axis. If not, the laser will clip the lens causing some of the light to be wasted. To convert the laser NA to the divergence angle (and vice-versa), use this formula: NA = n sin (φ) In most cases, n = 1 since the NA of the laser is defined in air Therefore, solving for the equation is simplified to: φ = s i n - ¹ (NA) It is important to note that φ is the half angle of the divergence cone and is given at the marginal ray (not 1/e² or half angle half max). After the minimum NA necessary for the lens is determined, next consider what beam diameter is preferred. Although ray-tracing is necessary to precisely determine the beam diameter for a given NA source with a particular lens, it can be approximated with the following formula: Beam Diameter 2 EFL NA where EFL is the effective focal length of the lens and NA is the numerical aperture of the source (not the NA of the lens). Important Note: Some laser manufacturers give the NA of the source in different terms, such as half max (50% point) or 1/e² (87% point). Whatever type of number is entered into the formula for the NA of the source will be the same type of number given for the beam diameter. For example, if the half max NA for a laser is used with the above formula, you will get the half max beam diameter. There is no simple way to convert from a half max number or a 1/e² beam diameter to a full beam diameter for a specific source because it depends on the intensity profile of the source itself. A reasonable approximation, though, for most edge emitting diode lasers is to assume a Gaussian beam profile. Using this beam profile, you can convert the beam diameters as follows: 1. To convert a half max beam diameter to a full beam diameter, multiply the diameter by 2.576. 2. To convert a 1/e² beam diameter to a full beam diameter, multiply the diameter by 1.517. Remember that most edge emitting diodes are elliptical, so the beam diameter will be different in the x-axis versus the y-axis. Use the formula above to calculate the beam diameter in both axes to determine the shape of the collimated, elliptical beam. For Fiber Coupling Another common use for aspheric lenses is to couple laser light into optical fibers. Choosing the right lens or lenses to do the coupling is important to maintain high efficiency in the optical system. The guide below is intended to show how best to do this while using off-theshelf components. This guide assumes that the input laser light has already been collimated (not diverging). When selecting a lens to focus light into a fiber, first consider what focal length lens is needed. Let s revisit the formula given previously: Solving for EFL it becomes: Beam Diameter 2 EFL NA EFL Beam Diameter 2 NA where NA is the numerical aperture of the fiber that is used for the coupling. It is important to note that the EFL value that is calculated above is the minimum EFL needed to couple the light completely into the fiber. Longer EFL lenses can be used, but the spot size on the fiber tip will become larger. Therefore, it is best practice to use the shortest EFL lens possible that is larger than the minimum value specified above. www.lightpath.com 12

Glass Aspheres for Laser Tools Single lens provides same performance as doublets and triplets Reduces system cost through simple, compact design Molded lenses for greater performance repeatability Designed for high volume production In today s manufacturing environment, laser tools are a common method for generating guidelines and measuring distances or surface profiles. These tools include laser levels, laser pointers, line projectors, laser scanners, and laser trackers. LightPath s aspheric lenses are designed for use in today s high performance laser tools and measurement systems. Aspheric lenses provide a single lens solution to laser projection. These aspheric lenses provide a cost savings over spherical doublets and triplets without sacrificing performance. Time consuming and expensive mounting and alignment of doublets and triplets can be replaced with a simple single lens mount. Aspheric lenses also have higher transmission than multi-lens systems due to less optical material and allow more compact packaging to be produced. Contact LightPath to take advantage of the power of Aspheric Optics for a simpler optical system.

Asphere Customization Capabilities Aspheric Hybrid Optics Refractive-diffractive design Color corrects with a single element Diffraction limited performance Custom F/1 and faster achromats available High performance, cost effective Diffractive Zone on an Aspheric Lens In multi-wavelength or polychromatic applications, the change in focal length due to wavelength can compromise lens performance. For example, if the application requires minimum spot size, as is required in data storage or communications systems, the spot size will change with wavelength, which can degrade system performance. In imaging applications, an uncorrected lens results in a blurry image. A colorcorrected lens is needed to minimize these effects. LightPath s line of optical products for minimizing chromatic aberrations using only a single optical element. These new glass, molded asphericdiffractive lenses, also called hybrid lenses, can be used over a range of wavelengths for many applications, such as endoscopes for medical and industrial applications, CCD cameras for imaging, as well as tunable lasers for communications products. Using LightPath s unique precision molded glass hybrid lenses, customers can now solve chromatic performance issues in a single glass lens, and reduce weight, volume and parts count at the same time. Molded In Place (MIP) Lenses LightPath s lenses can be molded directly into metallic holders, allowing the lenses to be welded or soldered into the package and eliminating the need to use epoxy. This can be an ideal solution for high volume automated assembly or in applications where strict outgassing requirements preclude the use of epoxy adhesives. Anamorphic Optics Most commercially available laser diodes project an elliptical beam due to the diode junction having a rectangular shape. This elliptical beam can create difficulties in many applications, such as laser to fiber coupling. LightPath s lens technology creates a simple solution to circularize and collimate many of the available laser diodes. By positioning the lens very close to the laser chip itself, these lenses provide a small circular and collimated beam, providing a very elegant and compact solution. www.lightpath.com 34
