Bandpass filters

We offer bandpass filter with broad blocking and/or an optmized transmittance region. Large blocking and low wavefront distortion can be optimized to your demands. 

H-alpha filter for astronomy

Large bandpass filters for astronomy having broad blocking and low wavefront distortion.

Narrow bandpass filter

Steep edges, high optical density in the blockband and highest transmission in the passband ensure the best suitability for e.g. biophotonics and laser applications.

i-line filter

For photolithography applications feature outstanding transmission at 365 nm combined with a narrow spectral bandwidth and excellent homogeneity.

Variable linear filters

The linear shifting bandpass across the length of the filter eliminates the need for multiple filters and provides a versatile solution for analytical and medical applications.
