G311322000 25.4 mm Dia. N-BK7 Double-Convex Lens; EFL=50mm Uncoated
The G311322000 is a high-quality, double-convex lens offered by Qioptiq Photonics. This lens, with a diameter of 25.4 mm, is designed for use in a variety of optical systems that require a focal length of 50mm. The lens is made from N-BK7, a popular optical glass due to its excellent optical properties and wide transparency range.
The lens's geometry is characterized by its base shape, which is circular, and its geometry, which is spherical. The first radius of curvature (R1) is 51.08, while the second radius of curvature (R2) is -51.08, indicating a symmetric convex-convex design. The edge thickness of the lens is 3.8mm, while the center thickness is 7mm, providing a robust and durable structure.
The lens is uncoated, which means it does not have any anti-reflective or other coatings. While this may result in a higher reflectivity at the air-glass interfaces, it also means the lens is more cost-effective and suitable for applications where such coatings are not necessary.
The lens is in stock and available for immediate purchase from the Qioptiq Photonics website. For more information, you can visit the provided weblink.
