  • Up to 1.3 MegaPixels, 5μm Pixel Size Sensors
  • Up to 1/2", S-Mount Lens
  • 3.6mm to 8mm Focal Length

TECHSPEC® Red Series M12 Lenses feature a high resolution, all glass element design. The slight negative (barrel) distortion can be easily factored out since the Angular Field of View is increased, thereby offering more workable field of view (FOV) in the object domain. Threaded for M12 x 0.5, these lenses are optimized for 1/3” and ½” sensor formats. TECHSPEC® Red Series M12 Lenses are ideal for demanding imaging applications.
