Optical Filter

Description

Filter can alter the characteristics of a beam of light. Absorption and particularly wavelength selective absorption is an important factor in the function of the filters. Filter can change the overall intensity of the beam without affecting its spectral content (e.g., neutral density filters). It can also change or separate the spectral content of the beam through wavelength-selective absorption or reflection (e.g., high-pass, low-pass, edge, dichroic and interference filters).
 
Advance Optics provide many kinds of optical filters including Colored Glass Filter,Interference Filter,Neutral Density Filter, etc.
