This is a Plano-Convex lens, a type of spherical lens, sourced from Qioptiq Photonics. The lens has a base shape of a circle and a diameter of 25.4 mm. The thickness at the edge of the lens is 3.2 mm, while the thickness at the center is 4 mm. The effective focal length (EFL) of this lens is 200 mm, making it suitable for applications that require a longer focal length.
The lens is made of N-BK7, a type of glass commonly used in optical applications due to its excellent optical properties. The radius of curvature (R1) of the curved surface is 102.92 mm. The lens does not have an inner or outer radius, indicating that it is a simple plano-convex lens.
The lens is coated with Qio Bbar Arb2nirnbk7 on both the front and back surfaces. This coating is designed to enhance the lens's performance in the 725-1050 nm wavelength range.
