Narrow Bandpass Interference Filters. Infrared Narrow Band Filters are designed for the detection and measurement of atmospheric gases. If you dont find a suitable filter for your application in the list below please contact Spectrogons sales team for further assistance. Infrared absorption NDIR gas sensing Environment management system. In most cases blocking is metal-dielectric from 200nm to Far IR 3000nm at OD4.
This square spectral shape is able to be achieved for bandwidths as narrow as 01 nm. A challenge of manufacturing ultra-narrow band pass filters is the need to precisely tune the filters passband wavelength across the full aperture of the filter. In most cases blocking is metal-dielectric from 200nm to Far IR 3000nm at OD4. With a filter which allows the monitoring of this specific gas absorption the measurement of gas concentration is possible. Large bandpass filters for astronomy having broad blocking and low wavefront distortion. Go to request form.
Bandpass Interference Filters are used extensively in a variety of biotech biomedical and quantitative chemical applications to selectively transmit a narrow range of wavelengths while blocking all others.
Narrow band Interference Filters optical filters to meet the most demanding requirements of customers. Infrared absorption NDIR gas sensing Environment management system. Go to request form. In most cases blocking is metal-dielectric from 200nm to Far IR 3000nm at OD4. Near-IR Interference Bandpass Filter. This square spectral shape is able to be achieved for bandwidths as narrow as 01 nm.
