89-011 20.0mm Dia. x 80.0mm FL; Plano-Convex Lens Laser V-Coat 633nm

The 89-011 is a high-quality Plano-Convex spherical lens, boasting a 20.0mm diameter and a focal length of 80.0mm. This lens is sourced from the renowned optical vendor, Edmund Optics, and is designed to work optimally with a wavelength of 633nm.

The lens is made from the highly regarded material, n-BK7 Schott, which is known for its excellent optical properties and durability. The base shape of the lens is circular, ensuring a wide field of view and minimal distortion.

The geometry of the lens is meticulously designed, with a thickness of 1.13mm at the edge and 2.35mm at the center. The effective focal length (EFL) is 80.0mm, and the radius of curvature (R1) is 41.48mm. The back focal length (BFL) is 78.45mm, and both the inner and outer radii are 0mm.

The lens features a laser V-coat coating on both the front and back surfaces, specifically designed for 633nm. This coating enhances the lens's performance by reducing reflection and increasing transmission, making it ideal for laser applications.
