This is the G063101329 model from Qioptiq Photonics, a 31.5 mm diameter Plano-Convex lens made of N-BAK4 material with a center thickness of 8.3 mm and an edge thickness of 2 mm. The lens has an effective focal length (EFL) of 40 mm and is designed for use with a wavelength of 588 nm.
The lens is coated with Qio HP Nbar ARHS-YAG on both the front and back surfaces, providing excellent anti-reflective properties. This coating is particularly useful in high-power laser applications, where minimal loss of light and efficient energy transmission are crucial.
The lens's geometry is spherical, with a radius of curvature of 22.874 mm on the convex side. The inner and outer radii are 0 mm, indicating a uniform curvature throughout the lens.
This lens is mounted, making it ready for immediate use in various optical systems. The weblink provided leads to the product page on Qioptiq's official website, where you can find more information and check the current stock status.
