This is a Plano-Convex Lens, a type of spherical lens, sourced from Edmund Optics. It has a circular base shape with a diameter of 4.0mm and a focal length of 6.0mm. The lens is made of n-BK7 Schott, a popular optical glass due to its excellent optical properties and relatively low cost.
The lens features a YAG-BBAR coating on both the front and back surfaces, specifically designed for the wavelength range of 500-1100nm. This coating enhances the lens's performance by reducing reflection and increasing transmission, making it ideal for various applications within this wavelength range.
The lens's geometry includes a thickness of 1.53mm at the edge and 2.26mm at the center. The front surface has a radius of curvature of 3.11mm, and the back focal length is 4.51mm. The lens does not have any inner or outer radius specified, indicating a uniform curvature.
