G312401400 31.5 mm Dia. N-BAK4 Plano-Convex Lens; EFL=40mm
This is the G312401400, a 31.5 mm diameter Plano-Convex lens from Qioptiq Photonics. The lens is made of N-BAK4 material, a type of glass known for its high refractive index and low dispersion, making it an excellent choice for imaging applications. The lens has an effective focal length (EFL) of 40mm, which is the distance from the lens's center to the focal point when the lens is focused at infinity.
The lens's geometry is characterized by its diameter, edge thickness, and center thickness. The diameter is 31.5mm, the edge thickness is 2mm, and the center thickness is 8.3mm. The lens's curvature is defined by its radii of curvature, with the first radius (R1) being 22.87mm. The lens's inner and outer radii are both 0, indicating that the lens is a simple Plano-Convex design.
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 image quality.
The lens is available from Qioptiq Photonics and is currently in stock. For more information, please refer to the vendor's website linked below.
