This is a Plano-Convex Lens from Qioptiq Photonics, designed with a 3 mm diameter and a focal length of 3 mm (EFL). The lens is made of N-BK7 Schott, a popular material in the optical industry due to its excellent optical properties and high damage threshold.
The lens geometry includes a thickness edge of 0.34 mm and a thickness center of 1.5 mm. The inner radius is 0, while the outer radius is also 0, indicating a plano surface on one side and a curved surface on the other. The curvature radius (r1) is 1.55 mm.
The lens is coated with Qio Silver RAGV 45 on both the front and back surfaces, which is a broadband anti-reflection coating designed for high performance across a wide range of wavelengths. The coating reduces surface reflections, enhancing transmission and improving overall system performance.
This lens is available for purchase on the Qioptiq Photonics website, and as of the last check, it is in stock. For more detailed information, you can visit the product page at https://www.qioptiq-shop.com/en/Precision-Optics/Singlets/Plano-Convex-Lenses/Plano-convex-lenses-unmounted.html.
