L-BCC112 50 mm Dia. Double-Concave Lens; EFL=-250mm Uncoated

The L-BCC112 is a 50 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 and features a unique double-concave geometry, making it an ideal choice for specific optical applications.

The lens's geometry includes a thickness edge of 4.9 mm and a thickness center of 2.5 mm, providing a robust structure while maintaining a sleek profile. The effective focal length (EFL) of this lens is -250mm, indicating its diverging nature, which is further emphasized by its radii of curvature, r1 (-259.232078) and r2 (259.232078). These radii contribute to the lens's double-concave shape, which is crucial for its optical performance.

The L-BCC112 is crafted from the high-quality material N-BK7 Schott, a borosilicate glass known for its excellent optical properties and durability. The lens is designed to work with a wavelength of 587.6 nm, making it suitable for a wide range of applications in the visible light spectrum.

Notably, this lens does not come with any coating, offering users the flexibility to apply coatings based on their specific requirements. However, users should be aware that the lens, in its current state, may be more susceptible to environmental factors and may not perform optimally in certain conditions.
