The SLB-50-4000PIR2 is a Plano-Convex Lens, a type of spherical lens, with a diameter of 50.0 mm and a focal length of 4000.0 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 optical glass, and features a Plano-Convex geometry, which is characterized by having one flat surface and one curved surface.
The lens has a thickness of 3.0 mm at the edge and 3.2 mm at the center. The effective focal length (EFL) is 4000.0 mm, and the back focal length (BFL) is 3997.9 mm. The radius of curvature of the curved surface is 2076 mm. The lens does not have any inner or outer radius, indicating a uniform thickness across the lens.
The SLB-50-4000PIR2 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 lens is currently in stock and available for immediate purchase. For more information, users can refer to the vendor's website through the provided weblink.
