This product is a Plano-Convex lens, sourced from the renowned optical component vendor, Edmund Optics. The lens, identified as 38-293-INK, is characterized by its circular base shape and spherical geometry. The lens has a diameter of 12.5mm and a thickness of 1.23mm at the edge, which gradually increases to 2.2mm at the center.

The lens's effective focal length (EFL) is 40mm, and it has a front radius (R1) of 20.67mm. The back focal length (BFL) of the lens is 38.55mm. The lens does not have any inner or outer radius specified, indicating a uniform curvature.

The lens is made of N-BK7 Schott, a popular optical glass known for its excellent optical properties and versatility. The lens is coated with EDM VIS-0 std curve on both the front and back surfaces, which is designed for visible light with a wavelength of 587.6nm. This coating enhances the lens's performance by reducing surface reflections and increasing transmission.
