Product Family Description

  • Compact APS (CA) Lens Ideal for Machine Vision
  • Supports 27.9mm APS-C Format Sensors
  • TFL Mount (M35 x 0.75, 17.5mm Flange) for Large Format Sensors

TECHSPEC® CA (Compact APS) Series Fixed Focal Length Lenses are designed for high resolution large format sensors. Covering the APS-C format sensors with a 28mm image circle, these lenses feature a TFL Mount. TFL Mounts feature a M35 x 0.75 thread with a 17.5mm flange distance, and offers the same flange distance, robustness, and ease of use as a C-Mount. TECHSPEC® CA Series Fixed Focal Length Lenses offer a compact size while accommodating large format sensors, making them ideal for machine vision and factory automation applications.
