SLB-50.8B-50PIR1 50.8 mm Dia. x 52.7 mm FL; Coated; Double-Convex Lens 633-1064nm

The SLB-50.8B-50PIR1 is a high-quality double-convex lens, boasting a diameter of 50.8 mm and a focal length of 52.7 mm. This lens is sourced from the reputable vendor, OptoSigma, and is crafted from the renowned material, n-bk7 schott.

The lens's geometry is characterized by its convex-convex shape, with a thickness of 3 mm at the edge and 16.3 mm at the center. The effective focal length (EFL) is 52.7 mm, while the back focal length (BFL) is 47.1 mm. The radii of curvature for the first and second surfaces are 51.9 mm and -51.9 mm, respectively.

The SLB-50.8B-50PIR1 is equipped with a broadband anti-reflection coating, specifically designed for the wavelength range of 633-1064 nm. This coating, denoted as 'opt ir1', is applied to both the front and back surfaces of the lens, enhancing its overall transmission and reducing unwanted reflections.

This lens is an excellent choice for a wide range of applications, particularly where high-quality imaging and light transmission are critical. Its robust construction, combined with its superior optical properties, make it a reliable and versatile component in any optical system.
