G314321322 25.4 mm Dia. N-BK7 Plano-Concave Lens; EFL=-50mm 450-700nm
This is a Plano-Concave lens, a type of spherical lens, sourced from Qioptiq Photonics. The lens has a base shape of a circle and a diameter of 25.4 mm. The center thickness of the lens is 1.5 mm, and it has an effective focal length (EFL) of -50 mm, making it a negative lens. The lens is made of N-BK7, a popular glass type in the optical industry, known for its excellent optical properties.
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 presumably a broadband anti-reflection coating optimized for visible light. This coating helps to reduce surface reflections, thereby increasing the amount of light transmitted through the lens.
The lens data indicates an inner radius of 0 mm and an outer radius of 0 mm, suggesting that the lens is unmounted. The provided web link leads to the vendor's website, where more information and purchasing options can be found. The link's status is "Valid - in stock", indicating that the lens is readily available for purchase.
