G312320329 22.4 mm Dia. N-BK7 Plano-Convex Lens; EFL=200mm 1064nm
This is a G312320329 Plano-Convex Lens, a high-quality optical component sourced from Qioptiq Photonics. The lens has a diameter of 22.4 mm and a center thickness of 2.7 mm, with a slightly thinner edge thickness of 2.1 mm. The lens's design includes a spherical shape with a radius of curvature of 104.41 mm on the convex side and a flat surface on the other side, making it a Plano-Convex lens.
The lens is made of N-BK7, a popular optical glass type known for its excellent optical properties, including a high Abbe number and low dispersion. This makes it suitable for various applications, especially where high image quality and low chromatic aberration are required.
The lens has an effective focal length (EFL) of 200 mm, which is the distance from the lens's center to the focal point when the lens is used in air. This EFL makes it suitable for use in imaging systems where a moderate magnification is needed.
The lens is coated with Qio HP Nbar ARHS-YAG on both the front and back surfaces. This coating enhances the lens's performance by reducing reflection and increasing transmission, especially in the 1064 nm wavelength region. This coating is particularly useful in laser applications where high transmission and low loss are essential.
