808nm Narrow Bandpass Filter

Filters are designed by their manufacturers to transmit or absorb different wavelengths of light. And they are widely used in scientific experiments and industrial applications where that change is necessary.
A Band Pass Filter is designed to pass signals only in a certain band of frequencies while rejecting all signals outside this band. Unlike the low pass filter which only get through signals of a low frequency range, a Band Pass Filters passes signals within a certain “band” or “spread” of frequencies without distorting the input signal or introducing extra noise.
In a receiver, a bandpass filter allows signals within a selected range of frequencies to be heard or decoded, while preventing signals at unwanted frequencies from getting through. A bandpass filter also optimizes the signal-to-noise ratio and sensitivity of a receiver.

VY Optoelectronics Co.,Ltd. can supply a full range of filter. They are short pass Filter, long pass Filter, band pass Filter, ultraviole Filtert, infrared Filter, heat absorbing Filter, and color temperature conversion filters. We use material by China to Schott, Hoya, and other manufacturers to process them. Metallic films, colored glasses and thin dielectric films filter are all available per your requirements.
