L-BCX151 30 mm Dia. Double-Convex Lens; EFL=1000mm Uncoated

The L-BCX151 is a 30 mm diameter double-convex lens with an effective focal length (EFL) of 1000mm, sourced from the renowned optical vendor, Ross Optical. This lens is a spherical type, specifically designed in a convex-convex base shape, ensuring a high degree of curvature for precise optical applications.

The lens geometry is meticulously crafted, with a thickness of 2mm at the edge and 2.2mm at the center, providing a sturdy yet lightweight component. The inner and outer radii are 0, indicating a symmetrical design, which is beneficial for maintaining uniformity in optical systems. The radii of curvature, R1 and R2, are -1033.23mm and 1033.23mm respectively, further emphasizing the lens's double-convex nature.

The lens 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 wavelength of 587.6nm suggests this lens is designed for use in the visible light spectrum.

Notably, this lens is uncoated, meaning it does not have any anti-reflective or other surface treatments. While this may result in a higher reflectivity index, it also ensures the lens maintains its optical properties without the potential alterations that coatings may introduce.
