L-PCX351 75 mm Dia. Plano-Convex Lens; EFL=750mm Uncoated

The L-PCX351 is a Plano-Convex lens with a diameter of 75 mm, sourced from the renowned optical vendor, Ross Optical. This lens is specifically designed for applications requiring a long effective focal length (EFL) of 750 mm, making it an ideal choice for scenarios demanding high magnification and narrow fields of view.

The lens geometry is characterized by its base shape, which is circular, ensuring uniform light distribution and minimal distortion. The edge thickness measures 3.5 mm, while the center thickness is 5.3 mm, providing robustness and structural integrity. The lens's inner and outer radii are both zero, indicating a uniform curvature throughout.

The L-PCX351 is made from the high-quality material n-bk7 schott, a borosilicate crown glass known for its excellent optical properties, including high transmittance and low dispersion. The wavelength of 587.6 nm is optimally suited for this lens, ensuring optimal performance in the visible light spectrum.

Notably, this lens is uncoated, meaning it does not have any additional layers to enhance light transmission or reduce surface reflections. While this may result in a slightly lower transmission rate and increased glare, it also means the lens is more cost-effective and easier to clean.
