45-500 20.0mm Dia. x 40.0mm FL; VIS-NIR Coated; Plano-Convex Lens VIS-NIR 400-1000nm

This is a Plano-Convex Lens, a type of spherical lens, sourced from the renowned optical components vendor, Edmund Optics. The lens has a diameter of 20.0mm and a focal length of 40.0mm, making it suitable for a wide range of applications.

The lens is made from the high-quality material n-BK7 Schott, a borosilicate glass known for its excellent optical properties. This material is particularly suitable for applications in the visible and near-infrared spectrum, as indicated by the coating on both the front and back surfaces of the lens. The coating, edm visnir0sp2002000, is specifically designed for use in the 400-1000nm range, further enhancing the lens's performance in these wavelengths.

The lens's geometry is also noteworthy. It has an edge thickness of 2.32mm and a center thickness of 4.9mm. The radius of curvature of the convex surface is 20.67mm, and the back focal length is 36.77mm. The lens's inner and outer radii are both 0mm, indicating a uniform curvature.

According to the vendor's information, this lens is currently in stock, making it readily available for immediate use. The detailed specifications, coupled with its availability, make this lens a reliable choice for various optical applications in the specified wavelength range.
