G312405322 31.5 mm Dia. N-BK7 Plano-Convex Lens; EFL=200mm 450-700nm
This is a G312405322 Plano-Convex Lens, a high-quality optical component sourced from Qioptiq Photonics. The lens, which has a base shape of a circle, is designed for use in the 450-700nm wavelength range, making it suitable for a wide range of optical applications.
The lens has a diameter of 31.5mm and a thickness at the edge of 2mm. The center thickness is 3.2mm, providing a good balance between weight and optical performance. The effective focal length (EFL) of this lens is 200mm, making it a medium to long-range focal length lens.
The lens is made from N-BK7, a popular optical glass known for its excellent optical properties and high transmittance in the visible spectrum. The lens is coated with qio bbar arb2visnbk7 on both the front and back surfaces, enhancing its durability and performance in the specified wavelength range.
The lens is spherical in shape, which is a common and versatile geometry in optical systems. The radius of curvature (R1) of the convex surface is 104.04mm. The lens does not have an inner radius (the radius of the concave surface) or an outer radius (the radius of the outer edge of the lens), indicating that it is a simple plano-convex lens.
