SLB-25.4-40PIR2 25.4 mm Dia. x 40.0 mm FL; Coated; Plano-Convex Lens 750-1550nm
The SLB-25.4-40PIR2 is a Plano-Convex Spherical Lens, characterized by its 25.4 mm diameter and 40.0 mm focal length. This lens is sourced from OptoSigma, a renowned vendor in the optical industry, and is available for purchase directly from their website.
The lens is fabricated from n-bk7 schott, a high-quality optical glass known for its excellent transparency and low auto-fluorescence. The lens's geometry includes a 1.9 mm edge thickness and a 6.2 mm center thickness, with an effective focal length (EFL) of 40 mm. The front and back surfaces of the lens are coated with opt ir2, a broadband anti-reflection coating designed for use in the 750-1550 nm wavelength range.
The lens's base shape is circular, and its inner and outer radii are 0 mm, indicating a flat inner surface and a curved outer surface. The radius of curvature for the outer surface is 20.76 mm, and the back focal length (BFL) is 36 mm.
