G314332322 12.7 mm Dia. N-BK7 Plano-Concave Lens; EFL=-50mm 450-700nm
This is a Plano-Concave lens with a 12.7 mm diameter, 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 has a center thickness of 1.5 mm and an effective focal length (EFL) of -50 mm, making it suitable for applications that require a concave lens.
The lens is designed to work within the wavelength range of 450-700 nm, which covers the visible light spectrum. It is coated with qio bbar arb2visnbk7 on both the front and back surfaces, which is a broadband anti-reflection coating specifically designed for N-BK7 glass in the visible range. This coating helps to reduce surface reflections, improving the overall transmission of the lens.
The lens geometry is spherical, with a radius of curvature of -26.039 mm for the concave surface. The lens is unmounted, providing flexibility for users to mount it according to their specific requirements. The item data indicates that this lens is in stock, and users can access more information and purchase it from the Qioptiq Photonics website.
