SLB-40B-250PIR1 40.0 mm Dia. x 250.6 mm FL; Coated; Double-Convex Lens 633-1064nm

The SLB-40B-250PIR1 is a high-quality spherical lens, boasting a convex-convex base shape and a circular design. This lens, sourced from the reputable vendor OptoSigma, is characterized by its 40.0 mm diameter and a focal length of 250.6 mm. The lens's edge thickness is 2 mm, while its center thickness measures 3.5 mm, providing a robust structure for various applications.

The lens's effective focal length (EFL) is 250.6 mm, and its first and second radii of curvature are 259.5 mm and -259.5 mm, respectively. The back focal length (BFL) is 249.4 mm, and both the inner and outer radii are 0 mm. These specifications make the lens suitable for a wide range of optical applications.

The SLB-40B-250PIR1 is made from n-bk7 schott, a popular material in the optical industry due to its excellent optical properties. The lens is coated with opt ir1 on both the front and back, enhancing its performance in the wavelength range of 633-1064nm. This coating ensures optimal light transmission and reduces unwanted reflections, making it an ideal choice for applications that require high-precision optics.
