SLB-05B-20PIR1 5.0 mm Dia. x 20.2 mm FL; Coated; Double-Convex Lens 633-1064nm
The SLB-05B-20PIR1 is a high-quality spherical lens from OptoSigma, designed for use in the 633-1064nm wavelength range. This lens, with a base shape of a circle, is a double-convex lens, meaning it has two convex surfaces.
The lens has a diameter of 5.0 mm and a thickness at the edge of 1.1 mm, while the thickness at the center is 1.4 mm. The effective focal length (EFL) of this lens is 20.2 mm, which is the distance from the lens's center to the focal point. The front and back surfaces of the lens have an IR1 coating, which is optimized for the infrared spectrum.
The lens is made of n-BK7 Schott, a popular optical glass known for its excellent optical properties and wide transparency range. The first radius of curvature (R1) is 20.76 mm, and the second radius of curvature (R2) is -20.76 mm, indicating the lens's convex-convex shape. The back focal length (BFL) of the lens is 19.8 mm.
This lens is ideal for applications that require a small, high-performance lens with a wide range of usable wavelengths. Its double-convex design provides a wide field of view and low distortion, making it suitable for various optical systems.
