L-PCX267 42 mm Dia. Plano-Convex Lens; EFL=150mm Uncoated

The L-PCX267 is a Plano-Convex lens with a diameter of 42 mm, sourced from the renowned optical component vendor, Ross Optical. This lens is specifically designed for use in optical systems that require a convex lens with a flat surface on one side. The Plano-Convex design allows for a wide range of applications, including use as a focusing lens or a beam shaping element.

The lens has an effective focal length (EFL) of 150mm, making it suitable for use in systems where a longer focal length is required. The EFL is a critical parameter in lens selection, as it directly influences the size and convergence of the image produced by the lens.

The lens is made from N-BK7 Schott glass, a popular material for optical components due to its excellent optical properties and high transmission across a wide range of wavelengths. The lens's geometry includes a thickness of 2mm at the edge and 4.9mm at the center, providing a robust and durable structure.

The lens's surface radii are 77.52mm for the curved surface and 0mm for the flat surface, resulting in a back focal length (BFL) of 147.33mm. The BFL is the distance from the rear surface of the lens to the focal point and is another crucial parameter in lens selection.

Notably, this lens is uncoated. Coatings are often applied to lenses to reduce surface reflections, increase transmission, or provide other desirable optical properties. However, uncoated lenses like the L-PCX267 can be advantageous in certain applications where specific coating properties are not required.
