Product Family Description

  • 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.
