The L-PCX211 is a 30 mm diameter Plano-Convex lens, sourced from the renowned optical vendor, Ross Optical. This lens, designed for general-purpose use, features an effective focal length (EFL) of 80mm, making it suitable for a wide range of optical applications.
The lens's geometry is characterized by a thickness of 2mm at the edge and 4.8mm at the center, with a base shape of a circle. The radius of curvature (R1) is 41.344mm, and the back focal length (BFL) is 77.13mm. The lens's inner and outer radii are both zero, indicating a planar surface on one side and a curved surface on the other.
The L-PCX211 is made from N-BK7 Schott, a popular optical glass due to its excellent optical properties and versatility. The wavelength for this lens is 587.6nm. The lens's shape is spherical, a common choice for its ease of manufacturing and good image quality.
Notably, this lens is uncoated. Coatings are often applied to lenses to reduce reflection, increase transmission, or provide other desirable optical properties. However, an uncoated lens can be advantageous in certain applications, such as when cost, simplicity, or specific optical characteristics are priorities.
