Glass ND filters attenuate light by absorption like gelatin ND filters. Glass ND filters are stronger and tend to have more uniform absorption characteristics. They also decay due to absorption, so care must be taken to avoid overheating. Attenuation is achieved by polishing the glass to the correct thickness.VY Optoelectronics Co.,Ltd. can supply a full of range of filters, neutral density filter, narrow band filter, band pass filter, long pass filter, short pass filter, interference filter, dichroic filter, cut-off filter, color filter, CCD filter and so on.

Description

Bandpass filter

A bandpass filter pass visible light and a specific portion of the visible (VIS) and near-infrared (NIR) spectrums. They are ideal for color camera applications that utilize daytime sunlight and NIR illumination at night. These filters achieve accurate color rendition by blocking interfering wavelengths and eliminate the need for dual sensor imaging.

About bandpass filter

An optical bandpass filter has a transmission band surrounded by two blocking bands that allow only a portion of the spectrum to pass. These optical bandpass filters have broad spectral bandwidths in either the ultraviolet, visible, or infrared spectrums. The nearly black filters absorb visible radiation. They are perfect for ultraviolet or infrared detection applications. UV filters are often used to selectively transmit the 254nm and 365nm mercury lines. IR filters are often used in nightvision and IR sensing systems.
