Bandpass Filters

An optical bandpass filter is used to isolate a band of wavelengths from the total spectrum by providing a band of high transmission and bands of high rejection of spectral energy on both the long and short wavelength sides of the transmission band. We make catalog and custom band-pass filters over the range of 200 nm to 16 µm with bandwidths ranging from 0.3nm in the UV/VIS to as wide as 4 µm in the IR.

Longpass Filters

Long-wave pass edge filters are specifically designed to transmit longer wavelengths than the cut-on wavelength while rejecting shorter wavelengths using either absorption or reflection.  Long pass filters are uesful in a variety of applications and can be used with shortpass filters for custom bandpass filtering.

Shortpass Filters

Short-wave pass edge filters are specifically designed to transmit wavelenghts shorter than the cut-off wavelength while rejecting longer wavelengths. Shortpass filters can be used in many applications and can be used with longpass filters for custom bandpass filtering.
