L-BCX143 30 mm Dia. Double-Convex Lens; EFL=63.5mm Uncoated

The L-BCX143 is a 30 mm diameter double-convex lens, sourced from the renowned optical vendor, Ross Optical. This lens is a spherical type, featuring a convex-convex base shape and a circular geometry. The lens's thickness at the edge is 2.5 mm, while the center thickness measures 6 mm, providing a robust structure for various optical applications.

The effective focal length (EFL) of this lens is 63.5 mm, making it suitable for medium to long-range optical systems. The first radius of curvature (R1) is 64.6 mm, and the second radius (R2) is -64.6 mm, indicating a symmetrical design that can minimize optical aberrations. The lens does not have an inner or outer radius, suggesting a uniform curvature throughout.

The L-BCX143 lens is made of n-BK7 Schott material, a high-quality optical glass known for its excellent transmission properties and low auto-fluorescence. This material is ideal for applications involving visible light, as it has a wavelength of 587.6 nm.

Notably, this lens is uncoated, meaning it does not have any anti-reflective or other surface treatments. While this may result in higher reflectivity, it also means the lens can be easily integrated into various systems without concerns about coating compatibility.
