This is a Plano-Convex Lens, type of spherical lens, offered by Qioptiq Photonics. It features a circular base shape and is designed for use in the 1064nm wavelength range. The lens has a diameter of 50 mm and a thickness at the edge of 2.4 mm, while the center thickness is 6.5 mm. The effective focal length (EFL) of this lens is 150 mm.
The lens is made of N-BK7, a popular optical glass from Schott, which is known for its excellent optical properties and wide transparency range. The lens's front and back surfaces are coated with Qio HP Nbar ARHS-YAG, a specialized anti-reflective coating designed for high power lasers in the YAG range.
The lens's geometry is defined by a radius of curvature of 78.3 mm on the convex side, with the concave side having an inner radius of 0 mm and an outer radius of 0 mm. This lens is unmounted, meaning it does not come with any housing or mounting hardware.
