This is a high-quality Plano-Convex lens from Qioptiq Photonics, designed for precision optical applications. The lens has a diameter of 12.7 mm and a focal length (EFL) of 300mm, making it suitable for use in the visible light spectrum, specifically between 450-700nm.
The lens is made from N-BK7, a popular optical glass due to its excellent optical properties and wide transparency range. The front and back surfaces of the lens are coated with "qio bbar arb2visnbk7", a broadband anti-reflection coating that enhances transmission and reduces surface reflections.
The lens geometry features a convex shape with a center thickness of 3mm and an edge thickness of 2.9mm. The inner and outer radii are 0mm, indicating a sharp transition from the flat plane to the curved surface.
This lens is mounted, making it ready for immediate use in your optical system. The item data also indicates that it is in stock and available for purchase, with a direct weblink provided for convenience.
