This is a G312327329 Plano-Convex Lens, a high-quality optical component sourced from Qioptiq Photonics. The lens has a diameter of 25.4 mm and a center thickness of 4 mm, with an edge thickness of 3.7 mm. The lens is made of N-BK7, a popular optical glass known for its excellent optical properties, making it suitable for a wide range of applications.
The lens has an effective focal length (EFL) of 500 mm at a wavelength of 1064 nm. The front and back surfaces of the lens are coated with Qio HP Nbar ARHS-YAG, a broadband antireflection coating designed for high power lasers in the near-infrared region. This coating helps to reduce surface reflections, improving the overall transmission of the lens.
The lens has a spherical shape with a radius of curvature of 260.39 mm for the convex surface. The concave surface has an inner radius of 0 mm, and the outer radius is also 0 mm. This lens is unmounted, providing flexibility for users to mount it according to their specific requirements.
