SLB-25-40PIR2 25.0 mm Dia. x 40.0 mm FL; Coated; Plano-Convex Lens 750-1550nm
The SLB-25-40PIR2 is a Plano-Convex lens with a diameter of 25.0 mm and a focal length of 40.0 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, where one side is flat (Plano) and the other side is curved (Convex). This geometry is particularly useful in applications where a collimated beam needs to be focused to a spot. The lens has an inner radius of 0 mm and an outer radius of 0 mm, indicating a uniform curvature.
The lens has a front and back coating of opt ir2, which is specifically designed for the infrared region of the spectrum (750-1550nm). This coating enhances the lens's performance by reducing surface reflections, thereby increasing transmission.
The lens has a thickness of 2 mm at the edge and 6.2 mm at the center. The effective focal length (EFL) is 40 mm, and the back focal length (BFL) is 36 mm. The radius of curvature (R1) is 20.76 mm.
The lens is currently in stock and can be purchased directly from the vendor's website. The link to the product page is provided for your convenience.
