50mm, M40 Mount, CA Series Fixed Focal Length Lens

Product Details 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 or M40 Mount. TFL Mounts feature an M35 x 0.75 thread with a 17.526mm flange distance and offer the same robustness and ease of use as C-Mount. M40 Mounts feature a M40 x 0.75 thread with also with a 17.526mm flange distance. M40 Mount lenses provides a robust, large format mounting solution ideal for high-resolution and larger image sensors with improved mechanical stability and optical performance compared to smaller format mounts. 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 .
