The 38-437-INK is a Plano-Convex lens, a type of spherical lens, sourced from Edmund Optics. This lens, with a diameter of 6.0mm, is designed for use within the visible light spectrum, specifically between 350-700nm. The lens features a front and back coating of edm vis ext, which is a broadband anti-reflection coating designed for high transmission in the visible spectrum.
The lens has a thickness of 0.84mm at the edge and 1.8mm at the center, with an effective focal length (EFL) of 10mm. The radius of curvature for the first surface (R1) is 5.17mm, and the back focal length (BFL) is 8.82mm. The lens is made of N-BK7 Schott, a popular optical glass due to its excellent optical properties and relatively low cost.
This lens is inked, which is a process where a dye is applied to the edge of the lens to indicate its orientation. The dye does not affect the optical properties of the lens but serves as a visual aid during assembly.
