25mm, f/11 Cw Series Fixed Focal Length Lens

Product Details Up to 2/3″, C-Mount Lens Waterproof (Cw) Versions of C Series Fixed Focal Length Lenses Meets IEC Ingress Protection Ratings of IPX7 and IPX9K Designed to Eliminate the Need for a Protective Lens Cover TECHSPEC Cw Series Fixed Focal Length Lenses are waterproof versions of our TECHSPEC C Series Fixed Focal Length Lenses . Designed to meet IEC Ingress Protection Codes IPX7 and IPX9K, these lenses withstand exposure to water up to 1 meter depth for 30 minutes and operate in close-range high pressure, high temperature water spray downs with the exception of all 3.5 and 4.5mm options which are IPX7. These lenses include a hydrophobic coated window to prevent water droplets from settling on the lens’ surface. To prevent moisture from entering the housing, the lenses are sealed with multiple O-rings. TECHSPEC Cw Series Fixed Focal Length Lenses are designed for up to 7.5 MegaPixel, 2/3″ sensors and are ideal for applications including food, pharma, automotive, and security. These lenses won the Bronze-Level 2021 Vision Systems Design Innovators Award. 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.
