L-BCX254 75 mm Dia. Double-Convex Lens; EFL=125mm Uncoated
The L-BCX254 is a 75 mm diameter Double-Convex lens, sourced from the renowned optical vendor, Ross Optical. This lens is a Spherical Lens of the Convex-Convex sub-type, boasting a circular base shape. The lens is designed with a high level of precision, featuring an effective focal length (EFL) of 125mm, making it suitable for a wide range of optical applications.
The lens's geometry is meticulously crafted, with a thickness at the edge of 3.6mm and a center thickness of 14.9mm. The radii of curvature for the first and second surfaces are R1=126.61mm and R2=-126.61mm respectively. The lens does not have an inner or outer radius, indicating a uniform curvature throughout.
The L-BCX254 is made from the high-quality material N-BK7 Schott, a borosilicate crown glass known for its excellent optical properties. The lens is designed to operate at a wavelength of 587.6nm. The lens's shape is spherical, a common choice for its ease of manufacturing and versatility in optical systems.
Notably, this lens is uncoated. Coatings are often applied to lenses to enhance their optical performance by reducing reflections, increasing transmission, or adding specific optical properties. However, this lens is in its bare form, offering a different set of optical characteristics that may be suitable for certain applications.
