39-550 25.4mm Dia. x 75mm FL; Coated; ZnSe Plano-Convex Lens BBAR 8-12µm
The 39-550 is a 25.4mm diameter, 75mm focal length plano-convex lens, designed for use in the 8-12µm spectral range. This lens is sourced from Edmund Optics, a leading provider of optical components, and is available for immediate purchase.
The lens is constructed from ZnSe (Zinc Selenide) material, identified as 'znse connolly' in the material database. This material is known for its excellent transmission properties in the infrared region, making it ideal for applications such as thermal imaging, spectroscopy, and gas sensing.
The lens features a front and back broadband anti-reflection (BBAR) coating, specifically designed for the 8-12µm range. This coating reduces surface reflections, thereby improving transmission and enhancing overall system performance. The coating type is 'edm dbbarl znse 812', as specified in the item data.
The geometry of the lens includes a 1.73mm edge thickness and a 2.5mm center thickness. The lens has a plano surface on one side and a convex surface on the other, with a radius of curvature of 105.2mm. The lens does not have an inner or outer radius.
