3 HISTORY OF LENSEL Lensel Optics was founded in 1979 by Mr. S. D. Rege. He was joined in 1981 by his cousin, Mr. S. M. Rege. Lensel started with the Compression Molding of Plastic Fresnel Lenses for use in Overhead Slide Projectors. From 1979 to 2005, Lensel was primarily in the Overhead Projector field supplying various Overhead Projector Components. As the Overhead Projector became obsolete, Lensel diversified into Glass Optics, Plastic Injection Molded Optics, Contract Manufacturing of Glass and Plastic Optics assemblies and AR Coatings. In 2008, having completed his BS & MS in Optical Engineering from the University of Arizona and after working in the US for 4 years, Mr. Sid Rege (son of Mr. S. D. Rege) joined Lensel. From 2009 onwards, Lensel has made a major push into supplying quality optics to overseas customers. From almost no exports 6 years ago, the company now earns over half of its Income from overseas customers.

18 COATING FACILITY SATISLOH SP-100 SPUTTER COATING SYSTEM 24 INCH IBP BOX COATER WITH EB GUN AND HHV DIGITAL THICKNESS MONITOR

19 COATING FACILITIES We have purchased the SP-100 Sputter Coating Chamber sold by Satisloh GmbH in August, We also have a 24 inch Box Coating System of Indian make (IBP System with EB Gun and HHV Digital Thickness Monitor) purchased in The Sputter Coating technology allows for extremely hard and durable coatings. The hardness and scratch resistance of the coatings made on the SP-100 is far superior to the standard MIL requirements of MIL 675C and MIL 48497A for severe abrasion. We have developed a wide range of coatings on the new Satisloh machine. These include the standard BBAR coating in the visible and near IR range as well as others such as the Ultrawide BBAR coating (covering 400 to 940 nm), Dual Wavelength coatings, Band-pass coatings, etc. We coat both glass and plastic lenses. We have a reflectance based Fiber Spectrophotometer from Filmetrics (purchased in Sept, 2015) as well as a transmission based regular Spectrophotometer from Thermo-Fisher in order to test our coatings.

20 COATINGS OFFERED BY LENSEL Standard BBAR Coating: Done on SP-100. Ravg<0.5% for 400 to 700 nm. Ravg<0.4% for 625 to 675 nm. Meets both MIL specs 675C and 48497A for severe abrasion. This coating can also be shifted to cover the NIR range from 550 nm to 870 nm Ultra-wide BBAR Coating: Done on SP-100. Ravg<0.8% for 400 to 940 nm. Meets all MIL specs. Very Low Reflection BBAR: For small wavelength ranges like 500 to 600nm, we can offer a coating with Ravg<0.2% over this range. Very Hard BBAR Coating: This is a very hard BBAR coating done on the SP-100. It is usually used on watch-glasses and other optics expected to undergo rough, out-door use. It has 1000 Vickers hardness and is claimed by Satisloh as the hardest AR coating available today. Ravg<1% for 400 to 700 nm. Single Layer MgF2 coating done on Box Coater Machine. We are able to offer very economical coatings on account of the large size of our box coater.

21 COATINGS OFFERED BY LENSEL BBAR Coating on Plastic Optics: This is the standard visible multi-layer coating done on plastic optics. It has an anti-scratch layer to improve the scratch resistance of the lenses. On customer request, we can also get the lenses dip coated (hard coated) from our associate followed by the AR coating. This gives maximum scratch resistance to plastic optics. This is done on the Box coater and is very cost effective. Dual Wavelength Coatings: These coatings done on the SP-100 are very popular in the Defense and Night Vision fields. It usually involves good performance over the visible or NIR range along with a peak transmission at some specific wavelength outside the range. Typical spec: Ravg<0.5% for 400 to 700 and R<0.5% at 1550 nm. Filters High pass, Band pass and notch. The SP-100 is capable of doing highly accurate coatings with layer stacks, which allows us to develop various types of filter coatings based on customer requirements.

23 ULTRAWIDE BBAR COATING Ravg < 0.8% for the extended range of 400 to 940 nm

24 TEST AND INSPECTION EQUIPMENT FUJINON INTERFEROMETER FILMETRICS SPECTROPHOTOMETER The Interferometer is used mainly for measuring the surface irregularity of spherical surfaces. The interferometer also comes with a digital scale that can be used for measuring radius of curvature. The interferometer can measure radii of curvature from +150 mm to -250 mm. We have two spectrophotometers. The Filmetrics instrument, shown above, is a fiber optic based spectrophotometer that can measure the reflectance of a sample. It can be used even on curved surfaces. Its range is from 380 nm to 1700 nm. We also have a Thermo Fisher transmission based Spectrophotometer that can measure transmission of flat samples from 200 nm to 1100 nm

25 TEST AND INSPECTION EQUIPMENT FOCOMETER MINOR MEASURING INSTRUMENTS We have made our own certified Focometer complete with collimator, measuring microscope, digital scale and rotation stage. The Focometer can measure Back Focal Distance up to 200 mm. The rotation stage allows us to rotate the lens while the measuring microscope allows us to measure the resulting deviation and thus compute the centration error. We measure the center thickness of the lens using a 1 micron LC Mitutoyo Digital Gauge mounted on a stand. We measure the diameter of the lens using a go-nogo gauge or Vernier Callipers. For Radii of Curvature outside the range of our interferometer, we use ball cup spherometers of various sizes

26 TEST AND INSPECTION EQUIPMENT LENS AESTHETICS INSPECTION TABLE VIDEO INSPECTION AND MEASUREMENT SYSTEM We have developed special tables that allow for quick and detailed inspection of the lenses for aesthetic defects like scratches, digs, pits etc. The table has a 4X Magnifier to allow for magnified view of the lens. The lens is viewed under a bright collimated halogen light beam that scatters off any defect (like a scratch) to make it immediately visible against a black background. For First Article Report for newly molded plastic injection molded components, we use a Video Inspection and Measurement systems to measure the linear dimensions and other features.
