SLB-30-35PIR2 30.0 mm Dia. x 35.0 mm FL; Coated; Plano-Convex Lens 750-1550nm
The SLB-30-35PIR2 is a Plano-Convex lens with a diameter of 30.0 mm and a focal length of 35.0 mm. This lens is sourced from OptoSigma, a renowned vendor in the optical industry. The lens is made of n-bk7 schott, a high-quality material known for its excellent optical properties.
The lens features a Plano-Convex geometry, meaning one side is flat (Plano) and the other side is curved (Convex). The radius of curvature of the curved surface is 18.17 mm. The lens has an effective focal length (EFL) of 35 mm, which is the distance from the center of the lens to the focal point when the lens is used in air. The back focal length (BFL) is 28.5 mm, which is the distance from the rear surface of the lens to the focal point.
The lens is coated with Opt IR2 on both the front and back surfaces. This coating enhances the lens's performance in the infrared spectrum, specifically between 750nm and 1550nm. The coating reduces reflection and increases transmission, improving the lens's overall efficiency.
The lens has a thickness of 2 mm at the edge and 9.9 mm at the center. The inner and outer radii are 0 mm, indicating that the lens has no curvature on the inner and outer edges.
