This is a Plano-Convex lens, type of spherical lens, with a circular base shape and a diameter of 35.0mm. The lens has a thickness of 1.7mm at the edge and 8.0mm at the center. The effective focal length (EFL) is 35.0mm, and the radius of curvature (R1) is 27.47mm. The back focal length (BFL) is 30.52mm, and both the inner and outer radii are 0mm.
The lens is made of N-SF11 Schott material, a lead-silicate glass known for its excellent optical properties in the near-infrared (NIR) range. The lens is coated with EDM NIR-II standard curve on both the front and back surfaces, enhancing its performance in the NIR II spectral range of 750-1550nm.
