G312356400 12.7 mm Dia. N-BK7 Plano-Convex Lens; EFL=200mm
This is a G312356400 12.7 mm diameter Plano-Convex lens, manufactured by Qioptiq Photonics. The lens is made of N-BK7, a popular glass type in the optical industry, known for its excellent optical properties and high damage threshold. The lens has a focal length (EFL) of 200mm, making it suitable for various applications that require long focal lengths.
The lens geometry is characterized by a diameter of 12.7 mm, a thickness at the edge of 2.8 mm, and a thickness at the center of 3 mm. The front surface of the lens has a radius of curvature of 102.92 mm, while the back surface is planar. The lens does not have any inner or outer radii, indicating a simple, straightforward design.
The lens is coated with Qio Silver RAGV 45 on both the front and back surfaces. This coating enhances the lens's performance by reducing reflection and increasing transmission, thereby improving the overall efficiency of the optical system.
The lens is currently in stock and can be purchased directly from the Qioptiq Photonics website. The provided weblink leads directly to the product page for easy access and purchase.
