Request InfoEdmund Optics Inc.Edmund Optics’ TechSpec short-wavelength-infrared (SWIR) longpass filters provide the high transmission and deep rejection necessary to isolate narrow spectral regions for use in a wide range of applications. The filters are designed to allow SWIR wavelengths to pass through, while blocking all visible light. They increase the image quality of InGaAs cameras in industrial machine vision, defense and solar cell inspection applications. They can be used as extended cold mirrors to eliminate damage or adverse effects as a result of heat buildup in a given system.
