This is a Plano-Concave lens with a diameter of 12.7 mm, sourced from Qioptiq Photonics. The lens is made of N-BK7, a popular glass type in the optical industry, known for its excellent optical properties. The lens's design features a concave shape on one side and a flat surface on the other, which results in a negative focal length of -500mm at a wavelength of 1064nm.
The lens has a center thickness of 1.5 mm and a clear aperture, with no inner or outer radius specified. The coating on both the front and back surfaces is Qio Hp Nbar Arhs-Yag, which is designed to enhance the lens's performance in specific applications.
This lens is a Spherical type, meaning it has a spherical surface, and it falls under the Sub Type of Spherical Lens (Plano-Concave). The item data indicates that it is unmounted, suggesting that it is intended to be integrated into a larger optical system.
