L-PCX439 25 mm Dia. Plano-Convex Lens; EFL=135mm Uncoated
The L-PCX439 is a 25 mm diameter Plano-Convex lens, sourced from Ross Optical, a renowned vendor in the optical industry. This lens is specifically designed for use in a variety of optical systems, offering a focal length of 135mm. The Plano-Convex design, where one side is flat and the other curved, is a common type of spherical lens.
The lens's geometry is meticulously crafted, with a thickness of 2mm at the edge and 3.1mm at the center. The curvature of the lens is defined by a radius of 69.768mm on the curved side. The Back Focal Length (BFL) is 133.46mm, and the lens does not have any inner or outer radius, indicating a uniform curvature.
The L-PCX439 lens 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, which is in the visible light spectrum.
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 where specific coatings may interfere with the desired optical effects.
