L-BCC105 50 mm Dia. Double-Concave Lens; EFL=-50mm Uncoated

The L-BCC105 is a 50 mm diameter Double-Concave Spherical Lens, offering a negative focal length (EFL) of -50mm. This lens is sourced from Ross Optical, a reputable vendor in the optical industry. The lens is designed with a base shape of a circle, making it suitable for a wide range of applications.

The lens's geometry is meticulously crafted, with a thickness of 15.3mm at the edge and 2.5mm at the center. The radii of curvature are -54.16682237mm for the first surface and 54.16682237mm for the second surface, contributing to its double-concave structure. The inner and outer radii are both zero, indicating a uniform curvature throughout the lens.

The lens is made from N-BK7 Schott, a high-quality optical glass known for its excellent optical properties. It is designed to work with a wavelength of 587.6nm, making it suitable for applications in the visible light spectrum.

Notably, this lens is uncoated, meaning it does not have any anti-reflective or other coatings applied to its surfaces. This may result in higher reflectivity and lower transmission compared to coated lenses, but it also means the lens is more cost-effective and simpler to manufacture.
