69-665 25mm Dia. x 50mm FL; Coated; Ge Plano-Convex Lens BBAR 8-12µm
This is a 25mm diameter, 50mm focal length plano-convex lens, manufactured by Edmund Optics. The lens is made of Germanium burnett, a material known for its excellent optical properties, particularly in the infrared spectrum.
The lens features a broadband anti-reflection (BBAR) coating on both the front and back surfaces, specifically designed for the 8-12µm wavelength range. This coating significantly reduces surface reflections, thereby improving transmission and overall optical performance.
The lens has a spherical shape, with a radius of curvature of 150.19mm on the convex side. The center thickness is 3mm, while the edge thickness is 2.48mm. The back focal length is 49.25mm, and the effective focal length is 50mm.
