Product Family Description

  • APS-C (27.9mm), TFL-Mount Lens or M40 Mount Lens
  • Greater than 30 MegaPixels, 3.45µm Pixel Size Sensors
  • High Resolution, Compact APS-C Lens (CA)
  • 35mm to 100mm Focal Length

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 an 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.

These lenses won the 3rd place 2020 Inspect Award and the Silver-Level 2020 VSD Innovators Award.
