This is a 1.5mm diameter by 1.0mm focal length plano-convex lens, coated with MgF2 for enhanced performance. The lens is sourced from Edmund Optics, a reputable vendor known for high-quality optical elements.
The lens is spherical in shape, with a base shape of a circle. It features a 1.5mm diameter and a thickness of 0.35mm at the edge, increasing to 0.8mm at the center. The effective focal length (EFL) is 1.0mm, and the radius of curvature (R1) is 0.85mm. The back focal length (BFL) is 0.57mm, and both the inner and outer radii are 0mm.
The lens is made from n-lasf9 Schott, a material known for its optical properties. It is designed to work optimally with a wavelength of 587.6nm. The lens is coated with MgF2 on both the front and back surfaces, following the standard curve from Edmund Optics. This coating enhances the lens's performance in the 400-700nm wavelength range.
