6mm, f/8 Cr Series Fixed Focal Length Lens

Product Details Up to 2/3″, C-Mount Lens Up to 7.5 MegaPixels, 2.8µm Pixel Size Sensors Ruggedized (Cr) Designs (50g Shock) of our C Series Lens 3.5mm to 50mm Focal Length Instrumentation (Ci) Versions Also Available TECHSPEC Compact Ruggedized (Cr) Series Fixed Focal Length Lenses provide Stabilized Ruggedization, protecting the lens from damage while maintaining optical pointing and positioning after shock and vibration. All individual lens elements are glued in place to reduce object shift on the image. In addition, these lenses feature robust mechanics with a simplified focus and stainless steel locking C-Mount clamp. TECHSPEC Cr Series Fixed Focal Length Lenses are ideal for calibrated imaging systems such as measurement and gauging, 3D stereo vision, robotics and sensing, autonomous vehicles, and object tracking. The 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. These lenses won the 1 st place 2018 Inspect Award and the Silver Level 2018 Innovators Award . Note: To learn more about ruggedization, visit our Ruggedization Resource Webpage . Edmund Optics has created a family of high performance optical designs (the C Series family) and developed 6 customized optomechanical solutions targeted for specific applications. These lens sub-families utilize the same optics as the C Series lenses providing the same optical performance in a variety of optomechanical solutions to meet your application requirements: C Series : Features locking cam focus and iris adjustment and is the most adjustable version of these optical designs; they are the typical high quality machine vision lenses. Also available with a VIS-NIR Broadband Anti-Reflection (BBAR) Coating . Ci Series : Simplified mechanics featuring fixed apertures with compact housing. Industrial Ruggedization for reduced size, cost, and locked focus. Cr Series: All optics glued in place and a locking C-clamp focus ring. Stabilized Ruggedization for reduced pixel shift and improved focus stability. Cx Series : Modular, flexible mechanics allows lenses to be taken apart for easy integration of accessories such as liquid lenses, apertures, and more. Liquid Lens Cx Series : Designed with an integrated liquid lens for quick autofocus. Cw Series: Waterproof, designed to meet IEC Ingress Protection Code IPX7 and IPX9K.
