This is a Plano-Convex lens, a type of spherical lens, offered by EKSMA Optics. The lens has a base shape of a circle and a diameter of 50.8 mm. The thickness at the edge of the lens is 4.4 mm, while the thickness at the center is 5 mm. The effective focal length (EFL) of the lens is 1000 mm.
The lens is made of BK7 Schott, a popular optical glass due to its excellent optical properties and relatively low cost. The front and back surfaces of the lens are coated with EKS AR532, an anti-reflection coating designed for a wavelength of 532 nm. This coating helps to reduce unwanted reflections and increase the transmission of light through the lens.
The lens is a great choice for applications that require a large diameter and long focal length. The anti-reflection coating makes it suitable for use in laser systems and other applications where high transmission and low loss are important.
