39-545 12.7mm Dia. x 35mm FL; Coated; ZnSe Plano-Convex Lens BBAR 8-12µm
The 39-545 is a 12.7mm diameter, 35mm focal length plano-convex lens, designed for use in the 8-12µm spectral range. This lens is sourced from Edmund Optics and is currently in stock.
The lens is made from ZnSe (Zinc Selenide) material, identified by the Material ID "znse connolly". The front and back surfaces of the lens are coated with a BBAR (Broadband Anti-Reflection) coating, specifically the "edm dbbarl znse 812" coating. This coating is designed to reduce reflection and increase transmission across the 8-12µm spectral range.
The lens has a planar (flat) front surface and a convex rear surface. The radius of curvature of the rear surface is 49.1mm. The lens has a thickness of 2.09mm at the edge and 2.5mm at the center. The effective focal length (EFL) of the lens is 35mm.
This lens is a spherical lens, meaning it has a spherical surface. The base shape of the lens is circular, indicating that the lens is circular in shape.
