G313216329 22.4 mm Dia. N-BK7 Double-Concave Lens; EFL=-100mm 1064nm

This is a G313216329 double-concave lens, featuring a 22.4 mm diameter and a center thickness of 1.5 mm. The lens is made of N-BK7, a popular optical glass from Schott, known for its excellent optical properties and versatility. The lens has a double-concave geometry, meaning it is curved inward on both sides, with radii of curvature R1=-104.41mm and R2=104.41mm. This particular lens has an effective focal length (EFL) of -100mm at a wavelength of 588nm.

The lens is coated with Qio HP Nbar ARHS-YAG on both the front and back surfaces. This coating is designed to reduce reflection and enhance transmission, making it suitable for use in high-power laser applications, particularly at the 1064nm wavelength. The lens's shape is spherical, a common choice for its simplicity and wide range of applications.
