G311378000 18 mm Dia. N-BK7 Double-Convex Lens; EFL=16mm Uncoated
This is a high-quality, uncoated double-convex lens from Qioptiq Photonics, designed for precision optical applications. The lens has a diameter of 18 mm and a focal length (EFL) of 16 mm, making it suitable for a wide range of uses.
The lens is made from N-BK7, a popular glass type known for its excellent optical properties. This material, also known as Schott glass, is renowned for its low dispersion and high Abbe number, making it ideal for applications that require high image quality and low chromatic aberration.
The lens geometry features a double-convex design, with radii of curvature of 15.179 mm for both the front and rear surfaces. This design provides a high degree of focusing power, making the lens suitable for use in imaging systems, beam shaping, and other applications where a tight focus is required.
The lens has a center thickness of 7 mm and an edge thickness of 1.1 mm, providing a robust and durable construction. Despite its robustness, the lens remains lightweight and easy to handle, making it a practical choice for a variety of applications.
The lens is uncoated, which means it does not have any anti-reflective coatings. While this may result in a higher level of reflection at the air-glass interfaces, it can also provide a cost-effective solution for applications where such coatings are not necessary.
The lens is currently in stock and available for purchase from the Qioptiq Photonics website. For more information, please refer to the provided weblink.
