G313215322 22.4 mm Dia. N-BK7 Double-Concave Lens; EFL=-50mm 450-700nm
The G313215322 is a high-quality double-concave lens, boasting a diameter of 22.4 mm and a center thickness of 1.5 mm. This lens is made from N-BK7, a popular optical glass known for its excellent transparency and low auto-fluorescence. The lens's concave-concave base shape contributes to its double-concave geometry, making it suitable for a wide range of applications.
The lens has an effective focal length (EFL) of -50mm, which is typical for concave lenses. This EFL is designed to work within the wavelength range of 450-700nm, making it suitable for use in various optical systems, including those that use visible light.
The lens's surface is coated with Qio Bbar Arb2visnbk7, a broadband anti-reflection coating that reduces surface reflections and increases transmission. This coating is applied to both the front and back surfaces of the lens, ensuring optimal performance.
