L-PCX109 12.5 mm Dia. Plano-Convex Lens; EFL=200mm Uncoated

The L-PCX109 is a Plano-Convex lens with a diameter of 12.5 mm, making it suitable for applications requiring compact optical components. This lens is manufactured by Ross Optical, a reputable vendor known for its high-quality optical elements.

The lens features an effective focal length (EFL) of 200mm, which is a crucial parameter in lens selection. The EFL determines the distance between the lens and the focal point where light rays converge. This lens's long EFL makes it ideal for applications requiring a tight focus over a considerable distance.

The geometry of the L-PCX109 includes a thickness of 1.5 mm at the edge and 1.7 mm at the center. The plano-convex shape, where one side is flat and the other is curved, allows for efficient light transmission and focusing. The lens's inner and outer radii are 0, indicating a flat inner surface and a curved outer surface.

The lens is made from N-BK7 Schott, a popular optical glass due to its excellent optical properties and versatility. This material is known for its low dispersion, high transmittance, and excellent homogeneity, making it suitable for various applications.

The wavelength of 587.6 nm suggests that this lens is designed for use in the visible light spectrum. However, it's important to note that the lens does not come with any coating, which may affect its performance in certain applications.
