L-PCX088 12 mm Dia. Plano-Convex Lens; EFL=72mm Uncoated

The L-PCX088 is a Plano-Convex lens with a diameter of 12 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 72mm, which is the distance from the lens's center to the focal point when the lens is imaging an object at infinity. This makes it suitable for use in systems where a long focal length is required.

The lens is made from N-BK7 Schott glass, a popular material for optical lenses due to its excellent optical properties and high transmission in the visible spectrum. The lens's geometry includes a thickness of 1.9mm at the edge and 2.4mm at the center, providing structural integrity while minimizing unnecessary weight.

The lens's surface radii are 37.2096mm for the curved surface and 0mm for the flat surface, resulting in a back focal length of 70.42mm. This combination of parameters contributes to the lens's high optical performance.

Notably, this lens is uncoated. While coatings can enhance the performance of lenses by reducing reflections and increasing transmission, an uncoated lens can be advantageous in certain applications where specific reflection properties are desired or where cost is a concern.
