This is a Plano-Convex lens, type of spherical lens, with a circular base shape, sourced from the reputable vendor Edmund Optics. The lens has a diameter of 20.0mm and a focal length of 25.0mm, designed to work optimally with a wavelength of 1064nm.
The lens geometry is meticulously crafted, with an edge thickness of 1.26mm and a center thickness of 4.0mm. The effective focal length (EFL) is 25.0mm, and the radius of curvature (R1) is 19.62mm. The back focal length (BFL) is 22.76mm, and both the inner and outer radii are 0mm, indicating a uniform curvature.
The lens is made from the high-quality material n-SF11 from Schott, a leading manufacturer of optical glass. This material is known for its excellent optical properties, making it suitable for a wide range of applications.
The lens features a laser V-coat coating on both the front and back, specifically designed for 1064nm. This coating enhances the lens's performance in laser applications, providing improved transmission and reduced reflection.
