L-BCX190 40 mm Dia. Double-Convex Lens; EFL=60mm Uncoated

The L-BCX190 is a 40 mm diameter Double-Convex lens, sourced from the renowned optical vendor, Ross Optical. This lens is a Spherical Lens of the Convex-Convex subtype, featuring a Circular base shape. The lens's geometry is meticulously designed, with a thickness edge of 2 mm and a thickness center of 8.8 mm, providing a robust structure for various optical applications.

The Effective Focal Length (EFL) of the L-BCX190 is 60mm, making it suitable for medium-range focus applications. The first radius of curvature (R1) is 60.48 mm, while the second radius (R2) is -60.48 mm, indicating a symmetrically curved lens surface that ensures uniform light refraction. The lens does not have an inner or outer radius, suggesting a uniform curvature throughout.

The L-BCX190 is made from the high-quality material N-BK7 Schott, a borosilicate glass known for its excellent optical properties, including low dispersion and high transmission across a wide spectrum. The lens is designed for use with a wavelength of 587.6 nm, 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 surface coatings. While this may result in a higher reflectivity rate, it also means the lens is more resistant to environmental factors and can be easily cleaned.
