Computar offers VIS-SWIR C-mount lenses for use in 400-1700nm multi-band SWIR imaging applications enabling SWIR cameras with Sony IMX990 / IMX-991, and other InGaAs sensors to see through many different types of materials, atmospheric conditions, and multispectral-reflective surfaces with no focus shift. All Computar SWIR lenses are glass with metal barrels, have locking screws, support pixel pitches down to 5µm, and offer an average of 0.1-0.2m minimum object distance (MOD).
