L-PCX162 20 mm Dia. Plano-Convex Lens; EFL=38mm Uncoated

The L-PCX162 is a 20 mm diameter Plano-Convex lens, sourced from the renowned optical vendor, Ross Optical. This lens is specifically designed for use in optical systems that require a convex lens with a flat plane on one side. The lens is uncoated, which means it does not have any additional layers to protect or enhance its optical properties.

The lens's geometry is characterized by its diameter, thickness, and effective focal length (EFL). The diameter is 20 mm, and the thickness varies from 1.2 mm at the edge to 3.9 mm at the center. The EFL of this lens is 38 mm, which is the distance from the lens's center to the point where it focuses parallel light rays.

The lens is made of N-BK7 Schott, a popular optical glass known for its excellent optical properties. The wavelength for which this lens is designed is 587.6 nm, which is the D-line of sodium, a common reference wavelength in optical design.

The L-PCX162 is a spherical lens, meaning it has a constant curvature throughout its surface. The inner and outer radii are both 0, indicating that the lens is a simple convex shape. The radius of curvature (R1) is 19.6384 mm.

Please note that the lens does not come with any coating. Coatings are often applied to lenses to reduce reflection, increase transmission, or provide other optical benefits. However, this lens is uncoated, which may be suitable for certain applications where such coatings are not required or desirable.
