The L-BCX261 is a 75 mm diameter double-convex lens with an effective focal length (EFL) of 750mm, sourced from the renowned optical vendor, Ross Optical. This lens is a spherical type, specifically designed with a convex-convex base shape, and is circular in geometry.
The lens's thickness at the edge is 3.5mm, while its center thickness measures 5.3mm. The first radius of curvature (R1) is 774.3, and the second radius (R2) is -774.3. The inner and outer radii are both zero.
The L-BCX261 is crafted from the high-quality material N-BK7 Schott, a borosilicate crown glass known for its excellent optical properties. The wavelength for this lens is 587.6nm.
Notably, this lens is uncoated, which means it does not have any anti-reflective or other surface coatings. While this may result in a higher level of light scattering and potential loss of light, it can also provide a more natural, unaltered optical path.
