Product Family Description

Improve Contrast
Isolate Spectral Regions/Colors
Precision Colored Glass

Ideal for machine vision, color filters are best used with black and white cameras to yield increased contrast and resolution. Utilizing the principal "Like Colors Lighten Like Colors" will maximize results. These colored glass filters provide wide fields of view unobtainable with angle-sensitive filters. Daylight Blue filters increase color temperature from 3300K to 5500K (daylight). Color camera settings (Red/Blue gain level and AWC) yield further optimization when used in conjunction with lamp selection (quartz-halogen and fluorescent).

All filters can be threaded together via identical male and female threads on each mount. Color filters can also be used in conjunction with mounted UV filters to block unwanted ultraviolet light and protect the filters in extreme environments.
