ABSTRACT:
Multi-layer light filters provide optimized gain control, contrast, and ambient light rejection through the addition of optical layers to a basic refraction light filter. These additional layers allow adjustment of the gain, contrast, and ambient light rejection of light filters in a substantially independent manner, and can be combined to simultaneously optimize these optical properties.
