This is a high-quality mounted double-convex lens from Qioptiq Photonics, designed for precision optical applications. The lens has a diameter of 31.5 mm and a focal length (EFL) of 130 mm, making it suitable for use in the visible light spectrum, specifically between 450 and 700 nm.
The lens is made from N-BK7, a popular optical glass from Schott, known for its excellent optical properties and high damage threshold. The base shape of the lens is circular, and it features a double-convex geometry with a center thickness of 4 mm and an edge thickness of 2.2 mm.
The lens is coated with Qio Bbar Arb2visnbk7 on both the front and back surfaces. This coating enhances the lens's performance in the visible light spectrum, reducing reflection and increasing transmission.
The lens is mounted, providing convenience and ease of use. According to the vendor's information, the lens is currently in stock and can be purchased directly from the Qioptiq Photonics website.
