87-953 50mm Dia. x 75mm FL; Coated; Ge Plano-Convex Lens BBAR 3-12µm
The 87-953 is a 50mm diameter, 75mm focal length plano-convex lens, designed for use in the 3-12µm spectral range. This lens is sourced from Edmund Optics, a leading provider of optical components.
The lens is made from Germanium burnett, a material known for its excellent transmission properties in the infrared spectrum. It features a broadband anti-reflection (BBAR) coating on both the front and back surfaces, which significantly reduces surface reflections and increases transmission.
The geometry of the lens includes a 2.61mm edge thickness and a 4mm center thickness. The front surface has a radius of curvature of 225.29mm, and the back focal length is 74mm. The lens has no inner or outer radius, indicating a flat surface on the non-curved side.
The lens is designed for use in a variety of applications that require high-quality infrared transmission. Its plano-convex design makes it suitable for use as a focusing element in optical systems. The lens's large diameter and long focal length also make it suitable for use in systems where high resolution and large field of view are required.
