Optical filter
Envin Scientific

Optical filters are used in a multitude of applications where it is necessary to select certain wavelengths of light whilst rejecting others. Envin Scientific has many years of experience in designing, manufacturing and supplying filters utilising many different technologies and techniques. Filters are available for use in the Ultraviolet, Visible & Infrared regions from 175nm to 25 microns. Measurement of the optical characteristics of these filters is supported by high performance Perkin Elmer Spectrophotometers.
