L-BCC024 12.5 mm Dia. Double-Concave Lens; EFL=-200mm Uncoated

The L-BCC024 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 an outer radius of 0 mm and an inner radius of 0 mm. The lens's geometry is characterized by its edge thickness of 1.7 mm and center thickness of 1.5 mm.

The lens has an effective focal length (EFL) of -200 mm, making it a powerful tool for optical systems that require strong negative magnification. The double-concave design, with radii of curvature R1 (-207.0092051 mm) and R2 (207.0092051 mm), contributes to its negative focal length.

This lens is made from the high-quality material N-BK7 Schott, a borosilicate crown glass known for its excellent optical properties, including low dispersion and high transmission in the visible spectrum. The wavelength for this lens is 587.6 nm, which falls within the green region of 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 altering dispersion. However, this lens is designed to function without these enhancements, offering a cost-effective solution for applications where coated lenses are not necessary.
