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.
