This is a Plano-Convex lens, a type of spherical lens, sourced from Qioptiq Photonics. The lens has a circular base shape with a diameter of 5 mm and a thickness of 0.57 mm at the edge, increasing to 2.5 mm at the center. The effective focal length (EFL) of this lens is 5 mm, making it suitable for applications that require a short 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 inner and outer radii of the lens are 0, indicating a plano-convex geometry, where one side of the lens is flat, and the other side is curved. The curvature of the convex side is defined by a radius of 2.58 mm.
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, making it suitable for use in near-infrared applications.
The lens is currently in stock and available for purchase on the Qioptiq Photonics website. For more information, please refer to the provided weblink.
