Green and Blue Filters for Industrial Applications, Jos. Schneider Optische Werke GmbH

Green and blue filters are band-pass filters with a specific spectral transmission characteristic that transmits light which is perceived by
the human eye as the corresponding color. These filters use absorptive glasses, that are robust, cost-effective and insensitive to angle of incidence.

In machine vision, one of their typical applications, they are used in front of a lens on a monochrome CCD or CMOS camera to improve image contract. The appropriate type of filter has to be selected with respect to the color of the object and the type and/or color of the illumination. These filters are available unmounted or in mounts with all common thread sizes.

Insensitive to angle of incidence

Available in mounts with all common thread sizes
