L-BCX145 30 mm Dia. Double-Convex Lens; EFL=75mm Uncoated
The L-BCX145 is a 30 mm diameter double-convex lens with an effective focal length (EFL) of 75mm, sourced from the renowned optical vendor, Ross Optical. This lens is a spherical type, specifically designed with a convex-convex base shape, ensuring a high degree of curvature for precise optical applications.
The lens's geometry is meticulously crafted, with a thickness of 2mm at the edge and 4.96mm at the center, providing a robust structure while maintaining a sleek profile. The radii of curvature for the first and second surfaces are 76.67mm and -76.67mm respectively, indicating a symmetrical design that can minimize spherical aberration.
The L-BCX145 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 across a wide spectrum. The wavelength for this lens is 587.6nm, ideal for visible light applications.
Notably, this lens is uncoated, offering a bare, unaltered glass surface. While coatings can enhance certain optical properties such as transmission and reflection, an uncoated lens provides a cost-effective solution for applications where such enhancements are not required.
