50mm f/2.8, HPr Series Fixed Focal Length Lens

Product Details 1.1″, C-Mount Lens Up to 20 MegaPixels, 1.85µm Pixel Size Sensors Ruggedized (HPr) Designs (50g Shock) of our HP Series Lens with Individual Optics Glued in Place 16mm to 50mm Focal Length Instrumentation (HPi) Versions Also Available TECHSPEC HPr Series Fixed Focal Length Lenses provide a stabilized ruggedization that maintains optical pointing stability after shock and vibration without sacrificing performance. This makes them ideal for calibrated imaging systems such as measurement and gauging, 3D stereo vision, robotics and sensing, autonomous vehicles, and object tracking. Every lens element is glued in place so that object to image mapping is always maintained. Additionally, the TECHSPEC HPr Series Fixed Focal Length Lenses feature a robust mechanical design with a simplified focus and stainless steel locking C-Mount clamp. Call for OEM Quantity Pricing. Edmund Optics has created a family of high performance optical designs (the HP Series family) and developed three customized optomechanical solutions targeted for specific applications. These lens sub-families utilize the same optics as the HP Series lenses providing the same optical performance in a variety of optomechanical solutions to meet your application requirements: HP 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. HPi Series : Simplified mechanics featuring fixed apertures with compact housing. Industrial Ruggedization for reduced size, cost, and locked focus. HPr Series: All optics glued in place and a locking C-clamp focus ring. Stabilized Ruggedization for reduced pixel shift and improved focus stability.
