This is a Plano-Convex lens, type SLB-P-M, sourced from OptoSigma, a renowned vendor in the optical industry. The lens is designed for use within the wavelength range of 400-700nm, making it suitable for a wide range of applications.
The lens has a base shape of a circle, with a diameter of 6.0 mm. The edge thickness is 1.0 mm, while the center thickness is 1.3 mm. The effective focal length (EFL) of the lens is 30.0 mm, and the radius of curvature (R1) is 15.57 mm. The back focal length (BFL) is 29.1 mm, and both the inner and outer radii are 0 mm.
The lens is made of n-BK7 Schott, a popular optical glass due to its excellent optical properties. The lens features a coating on both the front and back surfaces, specifically an opt M coating. This coating enhances the lens's performance by reducing reflection and increasing transmission.
