G312326000 25.4 mm Dia. N-BK7 Plano-Convex Lens; EFL=300mm Uncoated
The G312326000 is a Plano-Convex lens with a diameter of 25.4 mm, sourced from Qioptiq Photonics. This lens is designed for use in the visible spectrum, specifically at a wavelength of 588 nm. The lens is made from N-BK7, a popular glass type known for its excellent optical properties, including a high Abbe number and low dispersion.
The lens geometry is characterized by its spherical shape, with a radius of curvature of 153.99 mm for the convex surface. The lens has an effective focal length (EFL) of 300 mm, making it suitable for use in imaging systems where a long focal length is required. The lens thickness at the edge is 3.5 mm, while the center thickness is 4 mm, providing a robust structure.
The lens is uncoated, which means it does not have any anti-reflective coatings. While this may result in higher reflective losses, it also means that the lens is more cost-effective and simpler to manufacture. The lens is currently in stock and available for purchase on the Qioptiq Photonics website.
