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 7 mm and a thickness edge of 0.8 mm. The thickness at the center of the lens is 3.5 mm, and the effective focal length (EFL) is 7 mm. The lens is made of N-BK7 Schott, a popular optical glass, and is designed to work within the wavelength range of 450-700 nm.
The lens features a front and back coating of qio bbar arb2visnbk7, which is a broadband anti-reflection coating. This coating is specifically designed for use with N-BK7 glass and operates within the visible spectrum, reducing surface reflections and improving transmission.
The lens is currently in stock and available for purchase on the Qioptiq Photonics website. For more information, please refer to the provided weblink.
