Narrow Bandpass Filters
Schneider-Kreuznach robust narrow bandpass filters are designed to pass only a very narrow range of wavelengths of incident light, blocking the rest of the optical spectrum.
Overview
Transmit a small defined wavelength range
Narrow Bandpass filters for the industry
Schneider-Kreuznach magnetron sputtered industrial narrow bandpass filters feature steep slopes for sophisticated applications that require a sharp transition between high transmission and deep blocking at stable cut-on and cut-off wavelengths. The layers are applied by means of magnetron sputtering, a special coating process. Schneider-Kreuznach narrow bandpass filters are RoHS conform. Custom sizes are available on request.
What is the function of a narrow bandpass filter?
A narrow bandpass filter selectively transmits light within a narrow range of wavelengths while blocking light outside this range. The filter is designed to have a high degree of wavelength selectivity, which allows it to transmit only a specific narrow spectral band of light.
Where is a narrow bandpass filter used?
In industrial applications, narrow bandpass filters are used in a wide range of applications, including spectroscopy, imaging, and 3D measurement. They are used to isolate specific spectral lines or bands in a complex light source, enabling precise measurements and imaging.
