This is a Plano-Convex Lens, a type of spherical lens, sourced from Edmund Optics. It boasts a diameter of 6.0mm and a focal length of 15.0mm, making it a compact yet powerful optical component. The lens is made from n-BK7 Schott, a high-quality optical glass known for its excellent transparency and low dispersion.
The lens features a YAG-BBAR coating on both the front and back surfaces, within the wavelength range of 500-1100nm. This coating enhances the lens's performance by reducing reflection and increasing transmission, thereby improving light efficiency. The coating also provides protection against environmental factors, ensuring the lens maintains its high performance over time.
The geometry of the lens is well-defined, with a thickness of 1.4mm at the edge and 2.0mm at the center. The radius of curvature (R1) is 7.75mm, and the back focal length (BFL) is 13.68mm. The lens's base shape is circular, and it is designed to work optimally at a wavelength of 587.6nm.
