This is a Plano-Convex lens, type of spherical lens, offered by Qioptiq Photonics. The lens has a base shape of a circle and a diameter of 50 mm. The thickness at the edge of the lens is 2.6 mm, while the thickness at the center is 9 mm. The effective focal length (EFL) of this lens is 100 mm, making it suitable for a variety of applications.
The lens is made of N-BK7, a type of glass manufactured by Schott. This material is known for its excellent optical properties, making it a popular choice for many optical applications. The lens is designed to work within the wavelength range of 450-700 nm, which covers the visible light spectrum.
The lens features anti-reflective coatings on both the front and back surfaces. These coatings, identified as 'qio bbar arb2visnbk7', are designed to reduce reflections and increase transmission, thereby enhancing the performance of the lens.
