G312312525 40 mm Dia. N-BK7 Plano-Convex Lens; EFL=50mm 725-1050nm
This is a G312312525 Plano-Convex Lens, a high-quality optical component sourced from Qioptiq Photonics. The lens has a diameter of 40 mm and a center thickness of 11.8 mm, with an edge thickness of 2.6 mm. The lens's effective focal length (EFL) is 50 mm, making it suitable for a wide range of optical applications.
The lens is made from N-BK7, a popular optical glass known for its excellent optical properties. This material is characterized by a high refractive index and low dispersion, making it an ideal choice for various applications, including laser systems, beam shaping, and imaging systems.
The lens features a spherical shape, with a radius of curvature (R1) of 26.42 mm for the convex surface. The inner and outer radii are 0 mm, indicating a plano surface on the other side. This particular lens is designed to operate within the wavelength range of 725-1050 nm.
The lens is coated with Qio Bbar Arb2nirnbk7 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.
