8mm, f/4 UCi Series Fixed Focal Length Lens

Product Details Up to 1/1.8″, C-Mount, S-Mount Lens Up to 12 MegaPixels, 1.85µm Pixel Size Sensors Instrumentation (UCi) versions of our UC Series Lenses with Streamlined Mechanical Designs and Fixed Apertures 4mm to 35mm Focal Length TECHSPEC UCi Series Fixed Focal Length Lenses utilize the same optics as the TECHSPEC UC Series Lenses and feature 4K resolution. These lenses are designed for small pixels ≤2.2μm and offer a wide range of fixed apertures for a variety of applications. While optimized for 1/2.5″ sensors, many focal length options can be used on sensors up to 1/1.8”. TECHSPEC UCi Series Fixed Focal Length Lenses are ideal for OEM applications that require small, robust, and lightweight imaging solutions. Note: For adjustable aperture options, see our TECHSPEC UC Series Fixed Focal Length Lenses . Edmund Optics has created a family of high-performance ultra-compact optical designs (the UC Series family) and developed 3 customized optomechanical solutions targeted for specific applications. These lens sub-families utilize the same optics as the UC Series lenses providing the same optical performance in a variety of optomechanical solutions to meet your application requirements: UC Series : Features locking cam focus and iris adjustment in an ultra-compact design and is the most adjustable version of these optical designs; they are the typical high-quality machine vision lenses. UCi Series : Simplified mechanics featuring fixed apertures with compact housing. Industrial Ruggedization for reduced size, cost, and locked focus. UCr Series: All optics glued in place and a locking C-clamp focus ring. Stabilized Ruggedization for reduced pixel shift and improved focus stability. UCw Series : Waterproof, designed to meet IEC Ingress Protection Code IPX7 to withstand exposure to water up to 1 meter depth for 30 minutes.
