G314321400 25.4 mm Dia. N-BK7 Plano-Concave Lens; EFL=-50mm
The G314321400 is a 25.4 mm diameter Plano-Concave lens, manufactured by Qioptiq Photonics. This lens is made from N-BK7, a popular glass type in the optical industry, known for its excellent optical properties and versatility. The lens features a negative focal length (EFL) of -50mm, making it suitable for applications that require light convergence.
The lens's geometry includes a center thickness of 1.5mm and a radius of curvature (R1) of -26.039mm. The inner and outer radii are both zero, indicating a plano surface on one side and a concave surface on the other. The lens's spherical shape ensures consistent light bending, making it ideal for a wide range of optical systems.
The lens is coated with Qio Silver RAGV 45 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 of the optical system.
