This is a Plano-Convex lens with a diameter of 31.5 mm, sourced from Qioptiq Photonics. The lens is made of N-BK7, a popular glass type in the optical industry known for its excellent optical properties. The lens's geometry includes a thickness of 2.2 mm at the edge and 3 mm at the center, with a 300 mm effective focal length (EFL).
The lens's curvature is spherical, featuring a radius of 155.66 mm on the curved side. The inner and outer radii are both zero, indicating a plano surface on the other side. This lens is uncoated, meaning it does not have any additional layers to enhance its optical performance.
The lens is designed to work with a wavelength of 588 nm, making it suitable for applications that use this wavelength. It is currently in stock and available for purchase on the Qioptiq Photonics website.
