Schneider-Kreuznach - Narrow Bandpass Filters for Industrial Applications
Narrow bandpass filters are critical components in industrial applications, designed to selectively transmit a small, well-defined range of wavelengths while blocking the rest of the optical spectrum. Manufactured using magnetron sputtering technology, these filters achieve precise wavelength selectivity with stable cut-on and cut-off points. The layers are meticulously applied to ensure steep slope transitions, making them suitable for advanced applications like spectroscopy, 3D measurement, and imaging. Schneider-Kreuznach narrow bandpass filters conform to RoHS standards and come in custom sizes upon request. These filters are essential for isolating specific spectral lines or bands in complex light sources, enabling precise measurements and high-quality imaging. The robust construction ensures durability, and the specialized coatings enhance their performance in various environments, including LED and laser lighting, traffic surveillance, bioanalytics, and medical diagnostics.
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.
