SLB-50.8B-250PM 50.8 mm Dia. x 251.0 mm FL; Coated; Double-Convex Lens 400-700nm

The SLB-50.8B-250PM is a high-quality double-convex lens, boasting a diameter of 50.8 mm and a focal length of 251.0 mm. This lens is sourced from OptoSigma, a renowned vendor known for its precision optical components.

The lens is crafted from n-bk7 schott, a high-grade optical material known for its excellent transparency and low auto-fluorescence. This material is particularly suitable for applications that require high-resolution imaging and precise light transmission.

The SLB-50.8B-250PM features a double-convex geometry, with radii of curvature of 259.5 mm and -259.5 mm for the first and second surfaces, respectively. This geometry ensures a wide field of view and minimal distortion, making it ideal for a variety of applications, including microscopy, beam shaping, and laser focusing.

The lens has a center thickness of 5.4 mm and an edge thickness of 2.9 mm, providing robustness and durability. The edge and center thicknesses also contribute to the lens's excellent optical performance, minimizing spherical aberration and ensuring high-quality imaging.

The SLB-50.8B-250PM is coated with an opt m coating on both the front and back surfaces. This coating enhances the lens's light transmission capabilities, reducing reflection and increasing the amount of light that passes through the lens. The coating also provides protection against environmental factors, ensuring the lens's longevity and reliability.
