This is a Plano-Convex Lens from Qioptiq Photonics, designed for use in precision optics applications. The lens has a diameter of 3 mm and a thickness of 0.38 mm at the edge, increasing to 1 mm at the center. The effective focal length (EFL) of this lens is 2.5 mm, making it suitable for use in systems where a short focal length is required.
The lens is made from N-LASF9 material, a Schott glass variant known for its excellent optical properties. The front and back surfaces of the lens are coated with Qio HP Nbar ARHS-YAG, a specialized anti-reflective coating designed to reduce surface reflections and improve transmission at the 1064 nm wavelength.
The lens has a spherical shape, with a radius of curvature (R1) of 2.13 mm on the convex side. The inner and outer radii are both 0, indicating a planar surface on the opposite side. This lens is unmounted, meaning it does not come with any housing or mounting hardware.
