32-997 25mm Dia. x -50mm FL; MgF2 Coated; Double-Concave Lens 400-700nm

The 32-997 is a high-quality double-concave lens, boasting a 25mm diameter and a focal length of -50mm. This lens is sourced from the renowned optical vendor, Edmund Optics, and is available for immediate purchase, as indicated by its valid and in-stock weblink status.

The lens is constructed from n-BK7 Schott, a durable and optical-quality glass that ensures clear and precise light transmission. It features a double-concave geometry, with radii of curvature of -52.1mm and 52.1mm for the front and back surfaces, respectively. This geometry, combined with its negative focal length, makes it an ideal choice for applications that require light convergence or image inversion.

The lens's edges are 5.4mm thick, while the center measures 2.5mm, providing a robust structure that can withstand handling and mounting. The back focal length is -50.82mm, and the lens has no inner or outer radius, contributing to its concave shape.

The 32-997 is coated with EDM MgF2 std curve on both the front and back surfaces. This coating enhances the lens's performance by reducing reflection and increasing transmission within the 400-700nm wavelength range. This makes it suitable for a wide range of applications, including but not limited to, imaging systems, beam shaping, and laser applications.
