G063020400 22.4 mm Dia. N-BK7 Mounted Double-Convex Lens; EFL=20mm
This is a G063020400 22.4 mm Dia. N-BK7 Mounted Double-Convex Lens, with a focal length (EFL) of 20mm, sourced from Qioptiq Photonics. The lens is spherical in shape, with a base shape of a circle, and is made of N-BK7 Schott glass, a popular material for its high refractive index and low dispersion.
The lens has a diameter of 22.4mm and a thickness at the edge of 1.6mm, while the center thickness is 8.8mm. The front and back of the lens are coated with Qio Silver RAGV 45, a broadband anti-reflection coating that enhances transmission and reduces surface reflections.
The lens has a double-convex geometry, with radii of curvature of 19.248mm for both the first and second surfaces. The inner and outer radii are 0mm, indicating that the lens is not threaded or has any other special features on its edges.
The lens is designed to operate at a wavelength of 587.6nm. The item data does not specify whether this is a single-wavelength or broadband lens. Therefore, it's recommended to check with the vendor for more detailed specifications.
