This is a Plano-Convex lens from Qioptiq Photonics, designed with a base shape of a circle and a spherical geometry. The lens has a diameter of 22.4 mm and a thickness at the edge of 1.9 mm, while the center thickness is 3.5 mm. The effective focal length (EFL) of this lens is 80 mm, specifically designed for the wavelength of 588 nm.
The lens is made of N-BK7 Schott, a popular optical glass due to its excellent optical properties. It has an Anti-Reflection coating on both the front and back surfaces, specifically the Qio HP Nbar Arhs-Yag coating, which is optimized for use with YAG lasers at 1064 nm.
The lens's inner radius is 0, and the outer radius is also 0, indicating a plano-convex design with no curvature on the incident side. This design is often used to collimate or focus light, making it suitable for various applications in imaging and laser systems.
