65-271 2.5mm Dia. x 4.0mm FL; MgF2 Coated; Plano-Convex Lens MgF2 400-700nm
This is a 65-271 plano-convex lens, a type of spherical lens, sourced from the reputable optical vendor, Edmund Optics. The lens boasts a 2.5mm diameter and a 4.0mm focal length, making it suitable for a wide range of optical applications.
The lens is made from the high-quality material, n-lasf9 schott, which is known for its excellent optical properties. This material, combined with the lens's plano-convex geometry, ensures high-quality image formation and low distortion.
The lens features a front and back coating of edm mgf2 std curve. This magnesium fluoride coating enhances the lens's performance by reducing surface reflections and increasing transmission in the 400-700nm wavelength range. This coating is particularly beneficial in applications where high transmission and low loss are critical.
The lens's geometry includes a 0.56mm edge thickness and a 0.8mm center thickness. The inner and outer radii are 0, indicating a flat surface on one side of the lens and a curved surface on the other. The lens's effective focal length (EFL) is 4mm, and the back focal length (BFL) is 3.57mm.
