L-BCC021 12.5 mm Dia. Double-Concave Lens; EFL=-100mm Uncoated
The L-BCC021 is a 12.5 mm diameter Double-Concave Spherical Lens, sourced from the renowned optical vendor, Ross Optical. This lens is designed with a base shape of a circle, featuring a negative focal length (EFL) of -100mm, making it suitable for applications that require light convergence.
The lens's geometry includes an edge thickness of 1.9mm and a center thickness of 1.5mm, ensuring robustness and precision. The inner and outer radii are both zero, indicating a symmetrical curvature. The radii of curvature, R1 and R2, are -103.6826741mm and 103.6826741mm respectively, contributing to the lens's double-concave structure.
The L-BCC021 is made from the high-quality material, N-BK7 Schott, a borosilicate crown glass known for its excellent optical properties. The lens is uncoated, which means it does not have any additional layers to enhance its optical performance. However, it can be used in a wide range of applications, especially where the wavelength of interest is around 587.6nm.
This lens is currently in stock and more information about it can be found on the Ross Optical website.
