Edmund Optics C Series Fixed Focal Length SWIR Lenses
Compact C-Mount Lenses for 900–1700nm SWIR Imaging

Edmund Optics TECHSPEC® C Series Fixed Focal Length SWIR lenses are compact, lightweight C-mount lenses designed for short-wave infrared imaging applications in the 900–1700nm wavelength range. Featuring broadband anti-reflection (BBAR) coatings, large maximum apertures, and high-resolution optics, these lenses deliver reliable imaging performance for industrial machine vision, factory automation, and inspection applications.

Available in focal lengths from 3.5mm to 100mm, the C Series SWIR lenses support sensor formats up to 4/3" depending on the model, and resolutions up to 7.5 megapixels. The expanded focal length range provides wide-angle imaging for large fields of view as well as longer focal lengths for detailed inspection of smaller areas or more distant objects. Manufactured to tight tolerances for consistent optical performance, these lenses offer a cost-effective solution for SWIR imaging systems.

  • Designed for approximately 2.8µm pixel size sensors
  • Optimized for 900–1700nm SWIR imaging
  • Supports sensor formats up to 4/3", depending on model
  • Up to 7.5 megapixel resolution
  • C-mount lens interface
  • Large maximum apertures for low-light imaging
  • Short working distances on select models
