Edmund Optics C Series Fixed Focal Length SWIR lenses are C-mount, compact and lightweight lenses designed for sensors with a 2.8µm pixel size and lens format size up to 2/3". They feature large maximum apertures and broadband AR coatings, and are optimized for the 900-1700nm wavelength range. These industrial lenses feature extremely short working distances (as close as 75mm on some models) making them ideal for factory automation and machine vision tasks such as inspection.
