This is a Plano-Convex lens, type of spherical lens, offered by Qioptiq Photonics. The lens has a circular base shape with a diameter of 25.4 mm and a thickness of 2.4 mm at the edge, increasing to 4 mm at the center. The effective focal length (EFL) of this lens is 100 mm, making it suitable for applications that require a longer focal length.
The lens is made of N-BK7, a popular glass type in the optical industry due to its excellent optical properties. The lens is coated with Qio AL RALVIS AOI 45 on both the front and back surfaces, which enhances its performance in specific wavelengths and improves its durability.
The lens's geometry, including its inner and outer radii, is optimized for its specific application. The lens's design is spherical, which is a common choice for many optical systems due to its ease of manufacturing and good optical performance.
This lens is available from the Qioptiq Photonics website, and as of the time of data collection, it is in stock. The link to the product page is provided for your convenience.
