25mm HR Series Fixed Focal Length Lens

Product Details 2/3″, C-Mount Lens Up to 10 MegaPixels, 1.85µm Pixel Size Sensors High Resolution (HR), FA Lens for Machine Vision 8.5mm to 35mm Focal Length TECHSPEC HR Series Fixed Focal Length Lenses have multiple options available for each focal length to accommodate a variety of optimized working distance ranges. These lenses are ideal for machine vision (MV) and factory automation (FA) applications. TECHSPEC HR Series Fixed Focal Length Lenses are perfect for use on high-end 5 MegaPixel and 9 MegaPixel sensors that require resolution and high contrast. All lenses are C-Mount and feature locking focus, iris rings, and a front filter thread to allow the use of standard optical filters for increased versatility. Call for OEM Quantity Pricing. Edmund Optics has created a family of high performance optical designs (the HR Series family) and developed three customized optomechanical solutions targeted for specific applications. These lens sub-families utilize the same optics as the HR Series Lenses, providing the same optical performance in a variety of optomechanical solutions to meet your application requirements: HR Series: Features locking cam focus and iris adjustment. This is the most adjustable version of these optical designs and is the typical high quality machine vision lens. HRi Series : Simplified mechanics featuring fixed apertures with compact housing. Industrial Ruggedization for reduced size, cost, and locked focus. HRr Series : All optics glued in place and a locking C-clamp focus ring. Stabilized Ruggedization for reduced pixel shift and improved focus stability.
