780nm 785nm 808nm 830nm Hard Coated Glass Laser Bandpass Filters

Item Number:X-P22F6N0201

Bandpass filters are used to selectively transmit a portion of the light spectrum while rejecting all other wavelengths. Bandpass filters are ideal for a variety of applications such as fluorescence microscopy, spectroscopy, clinical chemistry, or imaging. These filters are commonly used in the life sciences, industrial or R&D industries.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.

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.
