optical interference filter

Optical interference filter introduction Introduction to Interference Filter Filter is a kind of optical element which can select the transmission, reflection, cut-off and attenuation of spectral wavelength. According to its function, it can be divided into band-pass filter, long wave pass filter, short wave pass filter, dichroic filter, neutral density filter, notch filter, cold mirror, hot mirror, color filter, etc. These filters...

...optical filters photo chromatic optical lenses filter 1. Infrared (ir) cut off filters are used with color CCD or CMOS imagers to produce accurate color images. An IR cut-off filter blocks the transmission of the infrared while passing the visible. This can be done with two optical techniques: absorption or reflection. Absorptive filters are made with special optical...
