25mm f/2.8 HPi+ Lens 1.2″

Product Details Instrumentation (HPi+) versions of our HP+ Series Lenses with Streamlined Mechanical Designs and Fixed Apertures 1.2”, C-Mount Lenses Up to 24.5 MegaPixels, 2.74µm Pixel Size Sensors 16mm to 35mm Focal Length TECHSPEC HPi+ Series Fixed Focal Length Lenses are designed to provide exceptional performance for the harsh demands of factory automation (FA) and machine vision. These lenses are designed for use with Sony’s 4th Generation Pregius S 24.5MP 1.2” IMX530 and IMX540 sensors. The f/2.8 aperture provide increased light throughput and high-resolution performance. TECHSPEC HPi+ Series Fixed Focal Length Lenses are C-Mount and are designed without an iris or focusing mechanism to drive down size, weight, and cost. These lenses are ideal for measurement and gauging, 3D stereo vision, and object tracking. HP+ Series: Features locking focus and iris rings to prevent unwanted adjustments and are designed for factory automation. 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.
