47-394 50.0mm Dia. x 175.0mm FL; VIS-NIR Coated; Plano-Convex Lens VIS-NIR 400-1000nm

This is a 50.0mm diameter, 175.0mm focal length Plano-Convex lens, specifically designed for the visible to near-infrared spectrum (VIS-NIR) range of 400-1000nm. The lens is sourced from the reputable vendor, Edmund Optics.

The lens is made of the high-quality material n-BK7 Schott, a borosilicate crown glass known for its excellent optical properties, including high transmission and low dispersion. This makes the lens suitable for a wide range of applications that require high-quality imaging and light transmission.

The lens features a plano-convex geometry, where one side is flat (plano) and the other side is curved (convex). This design provides a large, flat surface for easy integration into optical systems, while the curved surface focuses light. The lens has an inner radius of 0mm and an outer radius of 0mm, indicating a simple, straightforward design.

The lens is coated with a VIS-NIR coating, specifically the edm visnir0sp2002000 coating, on both the front and back surfaces. This coating enhances the lens's performance in the VIS-NIR range by reducing reflection and increasing transmission. The coating also provides protection against environmental factors, ensuring the lens maintains its performance over time.

The lens has a thickness of 5.48mm at the edge and 9mm at the center. The effective focal length (EFL) is 175mm, and the back focal length (BFL) is 169.05mm. The radius of curvature (R1) of the curved surface is 90.44mm.
