OPTICAL COMPONENTSSpherical LensesMicrospheresCylindrical LensesLens KitsAchromatic DoubletsMulti-ElementMicro OpticsMirrorsPrismsSubstrates & WindowsBeamsplittersPolarizersFilter & Apertures• Ideal for coupling optical fibers tolaser diodes and detectors• λ/4 surface figure for high performance• Single layer MgF 2 coated for visible orinfrared uses - uncoated also available• Coating axis is identified for ease of mounting• Focal lengths from 1 to 3mm - diameters from 2 to 5mmMicrospheres are convenient for coupling light into or out of fibers as well as for relayingimages in compact areas. The focal point of a sphere is very close to its surface so thesphere can be placed in contact with the fiber or another sphere for almost perfectcoupling. Three different coatings are available. All are single layer MgF 2 coatings whichhave been optimized for the visible range or either of the two diode laser bands. If acoated microsphere is chosen it will be necessary to maintain the coating axis when inuse. This axis is marked with a removable black dot for ease of location.Specifications & TolerancesFocal length: ±1%@633nmDiameter: ±0.001mmSphericity: λ/4 @633nm Surface quality: 20-10Material: LaSFN9MicrospheresORDERING&TECHNICAL SUPPORT(949) 851-5881FAX (949) 851-5058E-MAILsales@optosigma.comWEBwww.optosigma.comFocal Length(mm)Diameter, D(inches) (mm)PricePART NUMBER0.5 0.04 1.0 $ 19.00 025-01101.1 0.08 2.0 $ 12.50 025-01201.7 0.12 3.0 $ 14.00 025-01302.8 0.20 5.0 $ 15.00 025-01404.5 0.31 8.0 $ 25.00 025-0150For Single Layer AR Anti-Reflection coatings append appropriate suffix and add $15 to the price.- for 400-700nm append -A27- for 700-900nm append -A38- for 1300-1550nm append -A68Please ask us to quote for OEM quantities.104

OPTICAL COMPONENTSGradient Index MicrolensesSpherical LensesCylindrical Lenses• Cylindrical shape is easy to mount,easy to align• Available with both plano andconvex end profiles• Available for popular visible and IR laser wavelengths• Perfect solution for optical data transmission applications• Also available with the focal plane falling outside the lens for non-contact useOptical glass with a refractive index gradient provides a very efficient and simple way toproduce high quality imaging lenses. The material used in these microlenses is Selfoc ® .This material has a radial index gradient which causes focusing to occur within the material.The index variation is defined by and is normally specified by the constant √ A. The simplestform of gradient index lens is a simple cylinder of Selfoc ® . Collimated light incident onone end of the lens will be focused as it travels along the length of the cylinder. Thesemicrolenses are particularly useful for fiber and diode coupling since they can be mountedin close proximity to the source. They are ideal for use in optical data transmission. Weoffer gradient index microlenses with plano end faces and also in a convex configurationfor greater imaging power. The convex lenses have a spherical radius on one end only.Normally these lenses are a quarter pitch so that they focus a collimated input at the remoteface of the lens. However, we also offer lenses having slightly less than 1/4 pitch so thatthey focus just outside the lens. This is often more convenient since contact with the sourceor detector may be physically impossible. Two different numerical apertures are offered,0.46 and 0.6. These lenses are wavelength specific. They are supplied for the wavelengths633, 830, 1300 and 1560 nm and are Anti-Reflection coated for these wavelengths. Theywill work at other wavelengths but their focusing characteristics will vary from the publishedfigures and the coatings will not be optimized.1 pitch1/4 pitchLens KitsAchromatic DoubletsMulti-ElementMicro OpticsMirrorsPrismsSubstrates & WindowsSpecifications& TolerancesBeamsplittersPolarizersFilter & AperturesDiameter: ±0.02mmLength: +0, -0.04mmParallelism: ≤10arcminIndex gradient:±0.75%Clear aperture:70% of diameterMaterial: Dopedborosilicate glassCoating: NMARV-coatLIGHT PATH THROUGH GRADIENT INDEX MATERIALLDORDERING&TECHNICAL SUPPORT(949) 851-5881FAX (949) 851-5058E-MAILsales@optosigma.comWEBwww.optosigma.comfocal pointGRADIENT INDEX CONVEX MICROLENS105
