Jul 07, 2008 Manufactured with hard-coated Ion-Beam Sputtering technology, BrightLine® Laser Fluorescence filter sets are suited for use in laser-scanning and spinning-disk confocal microscopes, TIRF microscopes, as well as any fluorescence microscope or imaging system. Transition from reflection to transmission for both excitation and emission filters is less than 2.5% of longest laser wavelength to enable maximum capture of even weak signals close to laser line.

Jan 28, 2008 Right Light(TM) filter, when combined with Xenon-arc light technology, quartz outer filter, or CIRA (coated infrared absorbing) outer filter, provides full spectrum match to natural sunlight. Due to quality of cut-on to short wavelength UV match, experimenters can increase irradiance levels for accelerated operation without compromising correlation. Solution provides appropriate UV spectrum for weathering of automotive coatings and eliminates anomalous test results.

Nov 15, 2007 Suited for use in digital cameras, optical low pass filter (OLPF) employs structure wherein wide-band phase retardation film is sandwiched between pair of quartz plates. This design provides uniform light separation at all wavelengths of visible light, eliminating moire patterns across visible spectrum. Requiring only 2 quartz plates, this OLPF enhances quality of digital cameras and enables them to be made thinner.

Mar 06, 2007 By inserting Bullseye(TM) Apodizing Filter at aperture stop of imaging system, intensity variations of light source will be modified, which can result in flat top distribution. Density of filter decreases radially from dark center, where light is usually at its peak intensity, to outside edge, where it can become completely transparent. Customizable filter can be applied to various substrate types, and can be designed for any Gaussian function, regardless of beam size.

Nov 08, 2004 Optical Control Filter controls direction of emitted light from LCD displays, reducing reflections, and facilitating readability in direct sunlight. Polycarbonate film uses lamination bonding and vacuum deposition techniques to integrate privacy louver matrices with anti-reflection and anti-glare coating. Filter can be bonded directly to LCD displays measuring up to 18 in., making it suited for in-car, naval, and aerospace display applications.
