Geltech Molded Aspheric Lenses

Geltech Precision Molded Aspheric Lenses MODERN LENSES FOR MODERN APPLICATIONS For today s most 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 artificial limits focusing and collimating accuracy. Spherical System Although it has been known for centuries that spherical geometry is not optimal for refracting light, the expense of fabricating non-spherical (aspheric) surfaces has inhibited their use. With the breakthrough of LightPath s glass molding technology, this optimal lens geometry has become a reality. Aspherical Lens 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.

That asphere optics from LightPath can actually improve system performance and lower overall cost? 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. GUARANTEED PERFORMANCE LightPath s aspheric lenses are inspected and optically tested to ensure complete customer satisfaction. Visual cosmetic inspection for scratch/dig is performed on 100% of all lenses per MIL-PRF-13830B. Most lenses are guaranteed to pass 40/20 scratch/dig, but other inspection criteria, such as 60/40 or 20/10, can be provided upon request. www.amstechnologies.com/products/supplierspartners/supplierdetails/lightpath-technologies/ 4

Performance and Customization DIFFRACTION LIMITED 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 632.8nm. Most of our lenses are guaranteed to be diffraction limited, which means the RMS WFE < 0.070 λ at the design wavelength. Several of our standard lenses are available premounted in metal holders. Using our unique Mold-In-Place (MIP) technology, we can mold the lens directly inside a steel holder, eliminating the need for adhesives. We can also epoxy our lenses into stainless steel or Kovar mounts so you can weld them directly into your system. NUMERICAL APERTURE Our molded aspheric lenses are available with numerical apertures ranging from 0.15 up to 0.77. Lower numerical apertures are best when a large depth of focus is important or when you need nearly circular beams. Applications that would use a low numerical aperture include bar code scanners, surveying instruments, and small weapons sights. High numerical aperture lenses are important when you need the maximum light capture from a diode laser. High numerical aperture applications include data storage and industrial printing. SHAPES AND SIZES With lenses available in a multitude of shapes and sizes, up to 22mm in diameter, LightPath will be able to provide you with the perfect lens for your unique application. DIFFRACTIVE HYBRID LENSES By combining a refractive aspheric lens with a diffractive feature on one surface, you can achieve sophisticated beam shaping of your laser light. You can also use diffractive hybrid lenses to make your system achromatic over a range of wavelengths. LightPath hybrid lenses are custom designed to each particular application. CHOOSE FROM A VARIETY OF FORM FACTORS FOR CUSTOM DESIGNS LightPath s unique molding process allows us to custom manufacture a lens based on your specific requirements. We can provide lenses in a number of different form factors from a simple aspheric lens, to a wafer-based lens and even a lens molded into a metal housing. Some of LightPath s lens molding capabilities include: Wafer Lenses Anamorphic Lenses Molded-in-Place o Cylindrical Metal Holders o Square Holders o T-Holders o Custom Holders

Choosing the Right Aspheric Lens DIODE COLLIMATION One of the most common uses for aspheric lenses is in the collimation of edge emitting diode lasers. With over 70 standard lenses in LightPath s catalog to choose from, this can sometimes be a confusing task. 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 through 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 th e light to be wasted. To convert the NA to the divergence angle (and vice-versa), use this formula. NA = n sin (ϕ) 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 l/ e 2 (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 l/e 2 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: In most cases n = 1 since the NA of the laser is defined in air. Therefore, solving for the equation is simplified to: (ϕ) = sin -1 (NA) 1. To convert a half max beam diameter to a full beamdiameter, multiply the diameter by 2.576. 2. To convert a l/e 2 beam diameter to a full beam diameter, multiply the diameter by 1.517. It is important to note that ϕ is the half angle of the divergence cone and is given at the marginal ray (not l/e 2 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 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. www.amstechnologies.com/products/supplierspartners/supplierdetails/lightpath-technologies/ 8

Choosing the Right Aspheric Lens FIBER COUPLING For Fiber Coupling Another common use for apsheric 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-the-shelf 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. Beam Diameter ~= 2 EFL NA Solving for EFL it becomes: 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 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. Example: Suppose you wish to focus a collimated beam with a full beam diameter of 2.0mm into a 50 micron multimode fiber (Nufern GI50/125S). The fiber NA given by the manufacturer is approximately 0.20. Fiber NA is normally given at the 99% power point (as opposed to 1/e 2 or half max), we can use the full beam diameter given. EFL ~= Beam Diameter ~ = 2.0 ~ = 5.0mm 2 NA 2 0.2 So it is best to look for a lens with an EFL of at least 5.0mm and a clear aperture at least 1.942mm (in order to capture the full collimated beam). One might consider the 354430 lens for its 5mm EFL (at 1550nm), but its 1.5mm clear aperture will not capture the full collimated beam. A better choice might be the 354550 lens. Its 6.10mm EFL at 1550nm becomes 5.94mm at 660nm. The lens also has a large enough clear aperture (2.2mm) to capture the entire input beam.

GRADIUM Lenses Overview Aspheric Performance for High Power Laser Delivery Gradient index lenses for high power laser delivery Aspheric performance Smaller focused spot size Single lens replacement for conventional doublets High performance, cost effective Standard designs with diameters from 5 mm to 80 mm Standard Spherical Lens Standard spherical lenses suffer from spherical aberration, which artificially limits the focused spot. In high performance optical systems, spherical aberration, chromatic aberration, and astigmatism induce sweat on the brows of optical designers. These aberrations can prevent optical systems from reaching their full potential. Avoiding these factors in optical systems is often difficult without using multiple lens elements. LightPath s unique line of GRADIUM optics makes correcting these aberrations a practical reality. GRADIUM lenses are made from LightPath s proprietary axial gradient index glass. Its unique refractive qualities can be exploited to reduce spherical aberrations resulting in performance similar to single-term aspheres. GRADIUM lenses have been applied as simple singlets or doublets in complex multi-element systems. They have been very well received for use in high-power industrial laser systems; many of the world s largest Nd:YAG and fiber laser manufacturers now incorporate GRADIUM optics in their laser delivery systems. GRADIUM Lens GRADIUM s unique refractive index profile bends rays while traveling through the lens resulting in a better focused, smaller spot.

GRADIUM lenses take advantage of advances in the manufacturing of axial gradient glass. Large diameter blanks are fabricated with index changes (Δn) of up to 0.15, about 100 times that available from radial GRIN (GRadient INdex) technology. The large range in Δn available provides a substantial ability to correct aberrations, especially spherical. Broad Band Dual Band VC Standard Anti-Reflective Coatings Coating Code Wavelength Reflectivity per Surface % -BB2 650-1000 nm < 0.5 Average -DB3 1310/1550 nm < 0.25 Maximum -VC8 1064 nm < 0.25 Maximum The process used to produce the GRADIUM glass turns a series of SF glass layers into a single piece of gradient material. Unlike radial GRIN lenses, this process provides large diameter optical blanks with controlled index and dispersion profiles.

Infrared Optics from the Experts in Molded Glass Optics LEADERS IN CHALCOGENIDE GLASS MOLDING Enhanced thermal performance Reduced SWaP with lightweight optics Moldable solution for high volume production Molded aspheric lenses have revolutionized the digital camera market by allowing large volumes of high performance aspheric optics to be produced at a low cost. This technology has been limited to visible and near-infrared wavelengths, due to the crystalline structure of most infrared optical materials. Advances in chalcogenide materials have enabled compression molding for mid- and long-wavelength infrared (MWIR & LWIR) optics in a process similar to visible molded lenses. LightPath s Molded Infrared Optics technology enables the production of high performance, costeffective infrared aspheric lenses that do not rely on traditional diamond turning or lengthy polishing methods. Utilizing aspheric optics to reduce the number of lenses required for thermal imaging systems is a common practice. Traditional Germanium or Zinc Selenide aspheres are manufactured by diamond turning, which is a time-consuming and expensive process. Diamond turned lenses are made one at a time and the lenses suffer from variations in surface figure resulting in variations of performance from lens to lens. The infrared optics molding process allows lenses to be manufactured in high volume with a highly repeatable, consistent performance. Diffractive features are typically added to infrared aspheres to allow for sophisticated beam shaping or achromatization over a range of wavelengths. With LightPath s molding technologies, these features are molded directly into the surfaces of the lens. LightPath is a pioneer in the development, design and manufacturing of infrared optics made from molded chalcogenide glass. Our high volume production experience brings expertise and knowledge to your project as quantities for infrared optics continue to grow.

The dn/dt and CTE of the chalcogenide glass results in a smaller change in focal length as a function of temperature. Using molded infrared optics glass enables athermalization to occur using just a single lens or with a minimum of athermalization mechanics. Germanium suffers from transmission loss as temperature increases, especially as the temperature passes 60 C. LightPath s infrared optic aspheric lenses can be used in environments up to 130 C, providing a greater thermal operating range than Germanium.

Infrared Aspheric Lenses HIGH PERFORMANCE ASPHERES FOR LASER COLLIMATION IN THE INFRARED High numerical aperture for maximum collection efficiency Compact, single lens design Diffraction limited performance RoHS Compliant MWIR/LWIR collimating lenses have high numerical apertures. This allows for maximum light collection for MWIR and LWIR lasers, including quantum cascade lasers (QCL). The aspheric design enables a single lens to replace complex, multiple component optical systems and provide high quality infrared beams for sensing and analytical measurements. Infrared collimating lenses can also be molded directly into metal housings, eliminating the need to use epoxy to assemble the lenses. Housing materials such as SS304L, SS316, AL6061, and Inconel 718 are available. Molding into metal housings simplifies the mounting process while providing a hermetic seal between the lens and the rest of the package.
