G312329525 12.5 mm Dia. N-BK7 Plano-Convex Lens; EFL=20mm 725-1050nm
This is a Plano-Convex lens, a type of spherical lens, sourced from Qioptiq Photonics. The lens has a circular base shape and a diameter of 12.5 mm. The edge thickness of the lens is 1.4 mm, while the center thickness is 3.5 mm. The effective focal length (EFL) of the lens is 20 mm, making it suitable for a variety 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 10.44 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 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.
