SLB-20-170PIR2 20.0 mm Dia. x 170.0 mm FL; Coated; Plano-Convex Lens 750-1550nm
The SLB-20-170PIR2 is a Plano-Convex Lens, a type of spherical lens, with a diameter of 20.0 mm and a focal length of 170.0 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 is coated with opt ir2 on both the front and back surfaces.
The lens's geometry includes a thickness edge of 2.0 mm and a thickness center of 2.6 mm. The effective focal length (EFL) is 170.0 mm, and the radius of curvature (R1) is 88.23 mm. The back focal length (BFL) is 168.2 mm, and both the inner and outer radii are 0 mm. The lens is designed to operate within the wavelength range of 546.1 nm.
This lens is ideal for applications that require a broad wavelength range, such as 750-1550 nm, and its Plano-Convex design ensures excellent image quality and low distortion. The opt ir2 coating enhances the lens's performance by reducing reflection and increasing transmission. The lens's compact size and robust construction make it suitable for various applications, including optical systems, beam shaping, and imaging.
