G312312000 40 mm Dia. N-BK7 Plano-Convex Lens; EFL=50mm Uncoated
The G312312000 is a 40 mm diameter Plano-Convex lens, manufactured by Qioptiq Photonics. This lens, designed for use in the visible light spectrum at a wavelength of 588 nm, is made from N-BK7, a popular optical glass due to its excellent optical properties.
The lens features a planar (flat) surface on one side and a convex surface on the other, with a radii of curvature of 26.42 mm. The center thickness of the lens is 11.8 mm, while the edge thickness is 2.6 mm. The effective focal length (EFL) of the lens is 50 mm, making it suitable for a variety of optical applications.
The lens is uncoated, meaning it does not have any anti-reflective coatings. While this can lead to higher reflective losses, it also means the lens is more cost-effective and suitable for applications where such coatings are not necessary.
The lens's geometry and material make it suitable for use in a wide range of applications, including imaging systems, beam shaping, and laser applications. It is currently in stock and available for purchase on the Qioptiq Photonics website.
