This is a 35-718 2.0mm Dia. x 2.0mm FL Plano-Convex Lens, featuring a YAG-BBAR coating suitable for wavelengths between 500 and 1100nm. The lens is sourced from the reputable vendor, Edmund Optics.
The lens is a Spherical Lens of the Sub Type Plano-Convex, with a base shape of Circular. It has a diameter of 2mm and a thickness at the edge of 0.48mm, while the center thickness is 0.8mm. The Effective Focal Length (EFL) of the lens is 2mm.
The lens's front and back surfaces are coated with the YAG-BBAR coating, specifically the EDM YAGBBAR 5001100 coating. This coating enhances the lens's performance within the specified wavelength range.
The lens's geometry includes an inner radius of 0 and an outer radius of 0. The first radius of curvature (R1) is 1.7mm, and the back focal length (BFL) is 1.57mm.
The lens is made of n-lasf9 schott material, which is known for its high-quality optical properties. This lens is an excellent choice for applications that require a small, high-performance lens with a specific coating within the visible to near-infrared spectrum.
