L-PCX194 25.4 mm Dia. Plano-Convex Lens; EFL=400mm Uncoated

The L-PCX194 is a Plano-Convex lens with a diameter of 25.4 mm, making it suitable for a wide range of optical applications. This lens is sourced from Ross Optical, a reputable vendor known for their high-quality optical elements. The Plano-Convex design features a flat surface on one side and a curved surface on the other, which is beneficial for applications requiring a collimated beam or a reduced spherical aberration.

The lens has an effective focal length (EFL) of 400mm, which is the distance from the lens's center to the point where the light rays converge or diverge. This long EFL makes the L-PCX194 ideal for applications requiring a narrow beam or high magnification. The lens is uncoated, meaning it does not have any additional layers to enhance light transmission or reduce reflection. However, uncoated lenses can be advantageous in certain applications where minimal reflection is required.

The geometry of the lens includes a thickness of 3mm at the edge and 3.39mm at the center. The inner radius is 0mm, and the outer radius is also 0mm, indicating a symmetrical curvature. The lens is made from N-BK7 Schott, a popular optical glass known for its excellent optical properties and high damage threshold. The wavelength of 587.6nm suggests that this lens is designed for use in the visible light spectrum.
