This is a 10 mm diameter Plano-Concave lens, manufactured by Qioptiq Photonics, featuring a center thickness of 1 mm and effective focal length (EFL) of -10 mm. The lens is made of N-BK7 glass, a popular choice due to its excellent optical properties and wide transparency range. The lens's concave shape, with a radius of curvature of -5.168 mm, contributes to its negative focal length.
The lens is coated with Qio HP Nbar ARHS-YAG on both the front and back surfaces, enhancing its performance in the 1064 nm wavelength range. This coating reduces reflection and increases transmission, making it suitable for high-power laser applications.
The lens is mounted, providing convenience and ease of use. The item data does not provide specifics about the mount, but it can be assumed to be robust and designed for secure and stable positioning.
