G312330400 12.5 mm Dia. N-BK7 Plano-Convex Lens; EFL=25mm

This is a Plano-Convex lens, type of spherical lens, with a diameter of 12.5 mm, sourced from Qioptiq Photonics. The lens has a front surface that is flat (plano) and a back surface that is curved (convex). The lens's thickness at the edge is 1.4 mm, while at the center, it measures 3 mm. The Effective Focal Length (EFL) of this lens is 25 mm, which is the distance from the lens's center to the focal point.

The lens is made of N-BK7, a type of glass manufactured by Schott, which is known for its excellent optical properties. The lens is designed to operate at a wavelength of 588 nm.

The lens features a coating on both the front and back surfaces. The front surface is coated with qio silver ragv 45, and the back surface also has the same coating. This coating enhances the lens's performance by reducing reflection and increasing transmission.

The lens's shape is spherical, meaning it has the same curvature throughout its surface. The inner radius is 0, and the outer radius is also 0, indicating that the lens's curvature starts from its edge.

The lens is currently in stock and can be purchased from the Qioptiq Photonics website.
