SLB-05B-25PIR2 5.0 mm Dia. x 25.2 mm FL; Coated; Double-Convex Lens 750-1550nm
The SLB-05B-25PIR2 is a high-quality spherical lens, specifically a double-convex lens, sourced from OptoSigma. This lens boasts a 5.0 mm diameter and a focal length of 25.2 mm, making it suitable for a wide range of optical applications.
The lens is crafted from n-bk7 schott, a popular optical glass due to its excellent optical properties and versatility. The base shape of the lens is circular, and it features a coating of opt ir2 on both the front and back surfaces, enhancing its performance in the 750-1550nm wavelength range.
The geometry of the lens is well-defined, with a center thickness of 1.3 mm and an edge thickness of 1.1 mm. The inner and outer radii are not specified, indicating that they are not a significant factor in this lens's application. The back focal length (BFL) is 24.8 mm, a critical measurement for focusing light in optical systems.
