Product Family Description

  • Designed for True Factory Automation
  • Supports up to 2/3” Sensors
  • Large Maximum Aperture
  • Low Lens-to-Lens Variation

TECHSPEC® C Series VIS-NIR Fixed Focal Length Lenses are designed for use in machine vision applications that require NIR or VIS-NIR performance, with the working distance and resolution requirements of factory automation and inspection in mind. Featuring large maximum apertures and a Broadband Anti-Reflection (BBAR) coating designed out to 1000nm, these high performance lenses can be used in even the most restrictive lighting conditions. TECHSPEC® C Series VIS-NIR Fixed Focal Length Lenses are manufactured to a high tolerance, resulting in greater levels of imaging performance and low lens-to-lens variation, assuring simple installing into multiple systems. By combining high optical performance, industrial features, and small package size, the C Series VIS-NIR lenses represent a new standard in factory automation optics.

Also available with a VIS Broadband Anti-Reflection (BBAR) Coating.

Note: For IR imaging alone, #65-796 UV-VIS Cut Filter threads directly onto the M25.5 x 0.5 front filter thread of each lens.
