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 2.4 mm, while the thickness at the center is 4 mm. The effective focal length (EFL) of this lens is 100 mm, making it suitable for a wide range of optical applications.
The lens is made of N-BK7, a type of glass commonly used in optical systems due to its excellent optical properties. The radius of curvature for the first surface (R1) is 51.21 mm. The lens does not have an inner or outer radius, indicating a uniform curvature.
The lens is coated with qio bbar arb2nirnbk7 on both the front and back surfaces. This coating enhances the lens's performance in the 725-1050nm wavelength range, making it suitable for use in near-infrared (NIR) applications.
