G312340322 40 mm Dia. N-BK7 Plano-Convex Lens; EFL=60mm 450-700nm
This is a Plano-Convex lens, type of spherical lens, sourced from Qioptiq Photonics. The lens has a circular base shape with a diameter of 40 mm. The lens's edge thickness is 2.4 mm, while the center thickness is 9.5 mm. The effective focal length (EFL) of this lens is 60 mm, making it suitable for applications that require a longer focal length.
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.
The lens features a broadband anti-reflection coating on both the front and back surfaces. This coating, identified as 'qio bbar arb2visnbk7', is designed to reduce surface reflections and increase transmission, thereby enhancing the overall performance of the lens.
