VIS-SWIR lenses

Kowa’s VIS-SWIR lenses can cover a wavelength range from 400-1,700nm. And it’s designed to minimize focus shifting through the whole wavelength. This is made possible by Kowa’s original mechanical structure and special coating. The lens can even keep a transmission rate of 50% at 2,000nm and this will expand users’ possibility in machine vision inspection. NIR/SWIR cameras and hyperspectral cameras are getting more important in machine vision applications. These cameras can accurately analyze the reflective properties of materials over a wide wavelength range. This is used in image processing e.g. for material testing, separation and sorting, etc.
