The 88-917 is a Plano-Convex lens, a type of spherical lens, sourced from Edmund Optics. This lens boasts a substantial 40.0mm diameter and a focal length of 400.0mm, making it a formidable optical component. The lens is made from the renowned material, n-BK7 Schott, a borosilicate crown glass known for its excellent optical properties.
The lens features a YAG-BBAR coating on both the front and back surfaces. This coating, specifically designed for the wavelength range of 500-1100nm, enhances the lens's performance by reducing reflection and increasing transmission. The front surface has an outer radius of 206.72mm, while the back surface is planar, contributing to the lens's overall thickness of 4.03mm at the edge and 5mm at the center.
The lens's design includes a 0mm inner radius and a 0mm outer radius for the base shape, which is circular. The effective focal length (EFL) is 400mm, and the back focal length (BFL) is 396.7mm. This lens is currently in stock and available for immediate use.
