4mm FL f/4, Rugged Blue Series M12 Lens

Product Details Up to ½”, S-Mount Lens Up to 5 MegaPixels, 1.4µm Pixel Size Sensors Ruggedized Designs (50g Shock) of our Blue Series Lens with Individual Optics Glued in Place 2mm to 25mm Focal Length Non-Ruggedized Designs Also Available TECHSPEC Rugged Blue Series M12 Lenses have stabilized ruggedization , protecting the lens from damage, while reducing pixel shift and maintaining optical pointing stability after shock and vibration. Each lens consists of several precision glass optics that are glued in place inside a compact, aluminum housing. Gluing the glass optics prevents even the smallest movements that often cause pixel shift. Object to image mapping is maintained even after heavy shock and vibration; if the center of the object maps onto the center pixel, it will always map to that same center pixel. TECHSPEC Rugged Blue Series M12 Lenses are ideal for calibrated imaging applications such as measurement and gauging, 3D stereo vision, robotics and sensing, autonomous vehicles, and object tracking. These lenses are available in a variety of f/# options ranging from f/2.5 to f/8. Edmund Optics has created multiple product families of our TECHSPEC M12 S-Mount Lenses, which are designed to provide high resolution. These high performance lenses feature precision glass designs in a metal housing and have optimized specifications between each product family to meet your application needs.
