L-BCX236 50.8 mm Dia. Double-Convex Lens; EFL=125mm Uncoated

The L-BCX236 is a double-convex lens with a diameter of 50.8 mm, sourced from the renowned optical component vendor, Ross Optical. This lens is a spherical type, specifically designed with a convex-convex base shape, ensuring a high degree of focusing power. The lens is circular, making it suitable for a wide range of applications.

The lens's geometry is meticulously crafted, with an edge thickness of 3 mm and a center thickness of 8.09 mm. The effective focal length (EFL) is 125 mm, indicating a strong focusing capability. The first radius of curvature (R1) is 127.81 mm, while the second radius of curvature (R2) is -127.81 mm, demonstrating the lens's double-convex design. The inner and outer radii are both 0, suggesting a symmetrical lens structure.

The L-BCX236 is made from the high-quality material n-bk7 schott, a borosilicate glass known for its excellent optical properties. The lens is designed to work with a wavelength of 587.6 nm, making it suitable for a wide range of applications, including but not limited to, imaging, beam shaping, and laser systems.

Notably, this lens is uncoated, meaning it does not have any anti-reflective or other surface coatings. While this may result in higher reflectivity at the air-glass interfaces, it also means the lens can be easily customized with a coating of the user's choice.
