Product Family Description

  • Up to 4/3", C-Mount Lens
  • Up to 9 MegaPixels, 2.8µm Pixel Size Sensors
  • Double Gauss (DG) Lens with low distortion and high performance
  • 18mm to 75mm Focal Length

TECHSPEC® DG Series Fixed Focal Length Lenses utilize a Double Gauss design to provide high-performance, low distortion, compact size, and exceptional value, while exceeding the performance of typically available fixed focal length lenses. These lenses feature a mechanical design that allows the focusing movement to be motorized by the user, yields image resolution greater than 100 lp/mm, and have a standard C-Mount. For most applications, the camera-lens combination can be attached to workstations using the ¼-20 mount provided on the camera. TECHSPEC® DG Series Fixed Focal Length Lenses include focus ring, manual iris, and set screws to facilitate a low profile integration in machine vision applications. Typical applications for the DG Series lenses include machine vision, assembly-line integration, and measurement and image analysis.

Note: Industrial Boom Stands are recommended for building vibration-free workstations.
