M62.0 x 0.75, 1.5mm Thick, Uncoated, Machine Vision Mounted Sapphire Window

Product Details Protective Windows for Machine Vision Applications Windows Feature Extreme Surface Hardness and Chemical Resistance M25.5 to M62.0 Filter Threads Available Machine Vision Mounted Sapphire Windows are mounted in durable anodized aluminum housings with common filter threads for easy integration with most imaging lenses. The windows within the mount are manufactured from durable sapphire making them ideal for rugged environments because of their extreme surface hardness, high thermal conductivity, high dielectric constant and resistance to common chemical acids and alkalis. Machine Vision Mounted Sapphire Windows feature both male and female threads, allowing them to be combined with other mounted filters or polarizers. The uncoated windows are useful within a transmission range from 330 – 5500nm making them ideal for machine vision applications in the UV, Visible, and Infrared spectra.
