SWIR Longpass Filters

×
  • Block Visible Wavelengths
  • Ideal for Machine Vision Applications
  • Can Be Used as Cold Mirrors
  • Additional Longpass Edge Filters Available

Designed to pass short-wave infrared (SWIR) wavelengths while blocking visible light, TECHSPEC® SWIR Longpass Filters are ideal for increasing the image quality of InGaAs cameras in a variety of machine vision applications. These longpass edge filters are offered in multiple sizes and cut-on wavelengths. TECHSPEC SWIR Longpass Filters can also be used as extended cold mirrors to eliminate damage or adverse effects caused by heat build-up.
