G052117525 12.7 mm Dia. N-BK7 Mounted Plano-Convex Lens; EFL=300mm 725-1050nm

This is a Plano-Convex lens, a type of spherical lens with a flat (plano) surface on one side and a curved (convex) surface on the other. The lens is sourced from Qioptiq Photonics, a renowned vendor in the field of precision optics. It features a 12.7 mm diameter and is made of N-BK7, a popular glass type known for its excellent optical properties.

The lens has an effective focal length (EFL) of 300mm, which is the distance from the lens's center to the focal point where light rays converge. This makes it suitable for applications that require moderate to high magnification. The lens's thickness at the edge is 2.9mm, while its center thickness is 3mm, providing a good balance between weight and optical performance.

The lens is coated with Qio Bbar Arb2nirnbk7 on both the front and back surfaces. This coating enhances the lens's durability and performance by reducing reflection and increasing transmission in the 725-1050nm wavelength range. The lens's shape is spherical, meaning its curved surface is a portion of a sphere. This shape is common in optical systems due to its simplicity and versatility.
