L-BCX256 75 mm Dia. Double-Convex Lens; EFL=175mm Uncoated
The L-BCX256 is a high-quality double-convex lens offered by Ross Optical, a renowned vendor in the optical industry. This lens, with a diameter of 75 mm, is designed for use in a variety of optical applications, thanks to its impressive specifications.
The lens features a large effective focal length (EFL) of 175mm, making it suitable for applications that require a longer focal length. The double-convex design, characterized by its base shape of a circular geometry, ensures a wide field of view and minimal distortion.
The L-BCX256 is made from n-BK7 Schott, a high-grade optical glass known for its excellent optical properties. This material ensures high transmission and low dispersion, making it ideal for applications that require high image quality.
The lens has a center thickness of 10mm and an edge thickness of 2.2mm, providing robustness and durability. The radii of curvature for the first and second surfaces are 179.16mm and -179.16mm respectively, contributing to the lens's double-convex shape.
Notably, this lens is uncoated. While coatings can enhance the performance of lenses by reducing reflections, increasing transmission, and protecting the lens surface, an uncoated lens can be advantageous in certain applications where specific coating properties are not required.
