Thin Film Optical Coating

Deposition Sciences, Inc. (Santa Rosa, CA) has developed a line of thin film optical coatings that operate in the 3 - 5 micron and the 8 - 12 micron infrared (IR) spectral regions. A variety of coating types with these two wavelength regions are available, including AR (antireflection), high reflectors, beam splitters, dichroic coatings, and band pass filters. These thin film coatings can be applied onto various substrates including sapphire, silicon, germanium, zinc sulfide, zinc selenide, metals, ceramics, and glass types compatible with the extended infrared spectral region. The optical coatings are suitable for use in military, aerospace, and industrial tasks. For Free Info Visit http://info.ims.ca/10976-217

Laser Beam Expanders

The OSL laser beam expanders from Optical Surfaces (Surrey, UK) are designed to provide achromatic expansion of a collimated input source. With aluminum coatings they can operate from the UV to far IR range without adjustment. Alignment aids are supplied with each beam expander to ensure correct beam pointing. Specialist beam expanders requiring larger apertures (up to 400mm) or higher magnification (up to 100x) are available, as are both horizontal and vertical beam displacements. Custom beam expanders with a focusing capability for a given far field can be supplied for performance in LIDAR applications. An alternative beam expander is also available using two off-axis parabola with a common focus for Fizeau applications. OSL beam expanders are housed in a box assembly allowing them to be fixed to an optical table and transported to different sites without internal realignment. Test interferograms and an OPD map are supplied with every beam expander. For Free Info Visit http://info.ims.ca/10976-218

White SMD LEDs

Vishay Intertechnology (Malvern, PA) has released the VLMW1100 series of ultrabright white SMD LEDs that utilize InGaN technology to provide brightness. It comes in a 0603 footprint with dimensions of 1.6 mm × 0.8 mm × 0.6 mm. The devices offer an 80°angle of half-intensity, a luminous intensity ranging from 140 mcd to 280 mcd, and a typical color temperature of 5500 K. The LEDs feature an ESD-withstand voltage up to 1 kV, in accordance with JESD22-A114-B. The EIA- and ICE-standard 0603 SMD package for the VLMW1100 series is lead-frame-based and is filled with a mixture of epoxy and yellow converter. The yellow converter changes the blue emission partially to yellow, which mixes with the remaining blue to produce white. The VLMW1100 LEDs provide illumination for applications including backlighting in automotive dashboards, switches, and keypads, indicators and backlighting in telecommunications systems, audio and video equipment, office equipment, and flat backlighting for LCDs, switches, and symbols.

Tunable Laser System

Aculight Corp. (Bothell, WA) has announced the ArgosTM single-frequency, continuous-wave (CW) optical parametric oscillator (OPO) that provides multi-Watt, widely tunable, near- to mid-infrared output. Argos is a fiber-pumped, singly resonant OPO that provides continuous tuning from 1.4 to 2 microns and from 2.4 to 3.9 microns. It operates at room temperature and produces simultaneous output at two wavelengths, with available power between 1 and 5 Watts over the tuning range. The device offers 60 GHz mode-hop-free rapid tuning range. The OPO head measures 5" × 6" × 14" with a control unit of 10" × 19" × 19". Argos is suitable for applications in photoacoustic and cavity ringdown spectroscopy for trace gas detection. For Free Info Visit http://info.ims.ca/10976-222
