Optical Filter Guide

From SPECTRO - FILM
 

 

In the high technology work of constant change, one element, the "High Precision Optical Interference Filter" has remained essentially unchanged for almost 40 years.

These extremely compact optical elements offer a number of advantages over the other types of elements designed to isolate discreet spectra.

Products & Services
Optical bandpass filters are designed to transmit a specific waveband.  They are composed of many thin layers of dielectric materials, which have differing refractive indices to produce constructive and destructive interference in the transmitted light.

Long pass filters transmit a wide spectral band of long wavelength radiation while blocking short wavelength radiation. Short pass filters transmit a wide spectral band of short wavelength radiation and block long wave radiation. Search by Specification | Learn more about Long Pass Filters and Short Pass Filters
