SLB-20-40PIR2 20.0 mm Dia. x 40.0 mm FL; Coated; Plano-Convex Lens 750-1550nm
The SLB-20-40PIR2 is a Plano-Convex Spherical Lens, sourced from OptoSigma, with a diameter of 20.0 mm and a focal length of 40.0 mm. This lens is designed for use within the wavelength range of 750-1550nm, making it suitable for a variety of applications within the infrared spectrum.
The lens is fabricated from n-bk7 schott, a popular material in optical systems due to its excellent optical properties and versatility. The Plano-Convex geometry, with a center thickness of 4.6 mm and an edge thickness of 2.0 mm, ensures a wide field of view and minimal distortion.
The lens features a front and back coating of opt ir2, which is specifically designed to enhance performance within the infrared spectrum. This coating reduces surface reflections and improves transmission, thereby enhancing the overall efficiency and quality of the optical system.
The lens is circular in shape, with an inner radius of 0 mm and an outer radius of 0 mm. The effective focal length (EFL) is 40 mm, and the back focal length (BFL) is 37 mm. The radius of curvature (R1) is 20.76 mm.
