SLB-20-40PIR1 20.0 mm Dia. x 40.0 mm FL; Coated; Plano-Convex Lens 633-1064nm
The SLB-20-40PIR1 is a Plano-Convex lens, a type of spherical lens, sourced from OptoSigma. This lens has a base shape of a circle and is designed for use with a wavelength of 546.1 nm. The lens is made from n-bk7 schott material, a popular choice for its high refractive index and low dispersion.
The lens has a diameter of 20.0 mm and a thickness at the edge of 2.0 mm. The thickness at the center is 4.6 mm, and the effective focal length (EFL) is 40.0 mm. The front radius of curvature (R1) is 20.76 mm, and the back focal length (BFL) is 37.0 mm. The lens does not have an inner radius or an outer radius.
The SLB-20-40PIR1 is coated with opt ir1 on both the front and back surfaces. This coating enhances the lens's performance in the infrared region, specifically between 633 nm and 1064 nm. The lens is currently in stock and available for purchase through the OptoSigma website, as indicated by the "weblink status" field in the item data.
