L-BCC043 20 mm Dia. Double-Concave Lens; EFL=-35mm Uncoated
The L-BCC043 is a 20 mm diameter Double-Concave Spherical Lens, featuring a negative focal length (EFL) of -35mm, making it suitable for applications requiring light convergence. This lens is sourced from Ross Optical, a reputable vendor known for its high-quality optical elements.
The lens's base shape is circular, and it boasts a thickness of 4.7mm at the edge and 2mm at the center. The inner and outer radii are both zero, indicating a symmetrical curvature. The radii of curvature for the first and second surfaces are -36.95970761mm and 36.95970761mm, respectively.
The L-BCC043 is made from N-BK7 Schott, a popular optical glass due to its excellent optical properties and versatility. It is designed to work with a wavelength of 587.6nm, which is within the visible light spectrum.
Notably, this lens is uncoated. Coatings are often applied to lenses to enhance their optical performance by reducing reflection, increasing transmission, or providing other desirable properties. However, the absence of a coating in this case may be intentional, depending on the specific application requirements.
