This is a G312350322 40 mm diameter Plano-Convex lens, manufactured by Qioptiq Photonics. The lens is made of N-BK7, a popular glass type in the optical industry, known for its excellent optical properties and versatility. The lens has a plano-convex geometry, meaning one side is flat (plano) and the other side is curved (convex).
The lens has an effective focal length (EFL) of 80mm, making it suitable for applications that require moderate magnification. The lens is designed to work within the wavelength range of 450-700nm, which covers the visible light spectrum, making it ideal for applications in visible light optics.
The lens has a diameter of 40mm and a thickness of 2.3mm at the edge, increasing to 7.5mm at the center. The curvature of the lens is defined by a radius of 41.27mm. The lens is unmounted, providing flexibility for users to mount it according to their specific requirements.
The lens is coated with qio bbar arb2visnbk7 on both the front and back surfaces. This coating enhances the lens's performance by reducing reflection and increasing transmission, thereby improving the overall efficiency and quality of the optical system.
