SLB-60B-250PIR1 60.0 mm Dia. x 251.1 mm FL; Coated; Double-Convex Lens 633-1064nm

The SLB-60B-250PIR1 is a high-quality spherical lens, boasting a base shape of a circle and a double-convex design. This lens, sourced from the reputable vendor OptoSigma, is a n-bk7 biconvex lens with anti-reflective coating for the wavelength range of 633-1064nm.

The lens has a diameter of 60.0 mm and a thickness of 3.0 mm at the edge, while the center thickness measures 6.5 mm. The effective focal length (EFL) is 251.1 mm, and the front and back radii of curvature are 259.5 mm and -259.5 mm, respectively. The back focal length (BFL) is 248.9 mm, and both the inner and outer radii are 0 mm.

The lens is made of n-bk7 schott material, a popular choice for its excellent optical properties and versatility. The anti-reflective coating, Opt IR1, is applied to both the front and back surfaces, further enhancing the lens's performance by reducing unwanted reflections.

This lens is an ideal choice for applications that require a broad wavelength range, such as infrared spectroscopy, laser systems, and optical imaging. With its robust design and high-performance characteristics, the SLB-60B-250PIR1 is a reliable and efficient solution for various optical applications.
