Bandpass filters for the Industry

The very flat surface makes them ideal for high end inspection systems. Schneider-Kreuznach bandpass filters are RoHS conform. Custom sizes are available on request.

What is the function of a bandpass filter?
An optical bandpass filter is used in the industry to selectively transmit light of a particular range of wavelengths while blocking others. Schneider-Kreuznach filters are designed to eliminate unwanted wavelengths through a precisely defined structure of very thin layers. This technique achieves transmittances averaging over 95% and very steep slopes.

Where is a bandpass filter used?
In industrial applications, optical bandpass filters are used to improve the quality and accuracy of imaging systems such as cameras and microscopes. Bandpass filters are mainly used to eliminate interfering wavelengths. This significantly improves the image quality.
