Overview of
Optical Filters
Expert knowledge for complex requirements
Schneider-Kreuznach optical filters are high performance technical filters that have been adapted to the requirement of industrial users in research, engineering and production. These filters feature improved optical quality, are provided with detailed technical parameters, and have passed a strict quality assurance process.
Schneider-Kreuznach has the capability for coating and mechanic design and production, giving the advantage of providing customized filters. A µ micro water jet enables to cut each thinkable shape.
Schneider-Kreuznach industrial filters are characterized by the following key features:
Reproducibility and reliability
Top flatness and wavefront distortion guarantees no influence on image
Broad range of filter types and coatings
Broad range of diameters
Robust mechanics: metal mounts
Narrow Bandpass
