25mm SWIR Series Fixed Focal Length Lens

Product Details 4/3″, C-Mount, M42, F-Mount Lens Up to 3 MegaPixels, 10µm Pixel Size Sensors Designed and Optimized for SWIR (900-1700nm) InGaAs Sensors 25mm to 100mm Focal Length TECHSPEC SWIR Series Fixed Focal Length Imaging Lenses are compact, lightweight lenses designed for applications operating in the short-wave infrared (SWIR) spectra, ranging from 0.9 – 1.7μm. These lenses feature SWIR-optimized optical designs, glass types, and AR coatings from 0.8 – 1.8μm. Designed for high throughput and superior performance, the SWIR Series lenses are commercial-off-the shelf (COTS) lenses with low f/#’s, covering large 25mm sensors. TECHSPEC SWIR Series Fixed Focal Length Lenses are ideal for a range of applications including inspection, sorting, and quality control. There are focal lengths ranging from 25 to 100mm available for purchase. Specifications General Product Family: SWIR Series Note: Lens will cover larger 25.6mm and 20.5mm line scan sensors.
