This optical component is a plano-convex lens, sourced from Edmund Optics, featuring a 9.0mm diameter and a focal length of 20mm. The lens is made from the well-known N-BK7 glass from Schott, which is known for its excellent optical properties and versatility. The lens has a front and back coating of EDM VIS-EXT, designed to enhance transmission in the visible spectrum, specifically at a wavelength of 587.6nm.
The lens has a center thickness of 2.2mm and an edge thickness of 1.17mm, providing a balance between weight and optical performance. The inner and outer radii are 0mm, indicating a flat surface on the non-curved side of the lens. The curvature radius of the convex side is 10.34mm, which contributes to the lens's focal length.
This lens is suitable for applications that require high transmission in the visible spectrum, such as imaging systems, beam shaping, or collimation. The EDM VIS-EXT coating ensures high transmission and low reflectance, making it an ideal choice for such applications. The lens is currently in stock, as indicated by its weblink status, making it readily available for your optical needs.
