Abrisa (Santa Paula, Calif.) and its sister company, ZC&R Coatings for Optics (Torrance, Calif.), announce an optical coating that operates in the infrared spectral region from 8.0 to 12.0 Ám. The IR-BBAR-8-12 is a thorium-free coating, making it ideal for military and commercial applications. It can be tailored for a variety of substrate materials such as germanium (Ge), zinc selenide (ZnSe), zinc sulfide (ZnS), water clear zinc sulfide (CIZnS) and others. Currently fielded, operational and achieving high marks, IR-BBAR-8-12 optical coating joins the ZC&R IR coatings product line along with dual-mode visible/3-5 Ám, visible/8-12 Ám and standard 3-5 and 8-12 Ám coatings. ZC&R also provides optical thin film coatings for substrates such as silicon, sapphire, fused silica, and BK-7. www.abrisa.com or www.zcrcoatings.com
Deposition Sciences, Inc. (DSI, Santa Rosa, Calif.) announces the Infrared Reduction Filter specifically designed to block the IR wavelengths, yet transmit the visible wavelengths in CMOS camera applications. This special IR reduction coating can be applied to glass as thin as 0.003 inches. The filters then can be used as an encapsulating cover glass, increasing the signal-to-noise ratio for imaging devices being flooded with environmental infrared light. DSIĺs new CMOS IR filter blocks greater than 95 percent of the infrared radiation while transmitting more than 90 percent of the visible radiation. It is ideal for use in imaging applications where it is critical that IR radiation is blocked, reducing the effects of extraneous light and improving contrast and clarity in the imagery. The high-performance, uniform optical coatings are extremely stable over temperature and humidity changes.www.depsci.com
Edmund Optics (Barrington, N.J.) introduces TECHSPEC Compact Fixed Focal Length Lenses. Designed for use in machine vision applications, TECHSPEC Compact Fixed Focal Length lenses are ideally suited for factory automation, inspection or qualification. The lenses have been optically designed with the specific working distance and unique resolution requirements of factory automation and inspection in mind. These high-performance lenses feature large-maximum apertures, so they can be used in even the most restrictive lighting conditions. Each lens includes a broadband anti-reflection coating, which increases transmission by up to 12 percent over standard MgF2 coatings on competitive lenses. They are available in focal lengths of 8.5 mm, 12 mm, 16 mm, 25 mm and 35 mm and support up to 2/3-inch sensors. TECHSPEC lenses feature a locking iris and include a convenient focus adjustment with recessed set screws to prevent unintentional lens adjustments. www.edmundoptics.com
Jenoptik (Jena, Germany) offers new variable 1x-4x Beam Expanders with quartz lenses as well as F-Theta JENarTM lenses for large scan field diameters of 170 mm.Two new F-Theta JENarTM lenses with a focal length of 170mm for 532nm and 1064nm are made for high imaging quality.These lenses are corrected to avoid focused back reflections within the lens and close to the recommended galvo mirror positions. Against the background of steadily rising laser power the lenses are manufactured out of high-resistant materials to minimize lens damages. www.jenoptik-los.com
Sensors Unlimited, Inc., part of Goodrich Corp. (Princeton, N.J.), introduces the high-performance SWIR Optimized 50mm Lens for advanced imaging in the 0.7 to 1.7 micron spectral range. Ruggedly designed, it features a manual locking focus for steady performance with reliable operation and advanced optics that deliver greater than 90 percent throughput from 0.9 to 1.7 microns. The new 50mm focal length lens has a fixed aperture at f/1.4 that provides sharp imagery, with extremely low distortion.The SWIR SOLO 50 performs exceptionally well with Sensors Unlimitedĺs high sensitivity, InGaAs-SWIR, KT and SD camera families. Designed for large focal plane arrays (up to 640 x 512 with a 25-micron pixel pitch), the optics are ideal for demanding, low-light-level imaging tasks. High-performance imaging applications include 24-hour, day and night surveillance, UAVs, imaging lasers, and driver vision enhancement. www.sensorsinc.com
