L-PCX237 20 mm Dia. Plano-Convex Lens; EFL=40mm Uncoated
The L-PCX237 is a 20 mm diameter Plano-Convex lens, sourced from the renowned optical component vendor, Ross Optical. This lens, with its simple yet effective design, is a Spherical Lens, specifically a Plano-Convex lens, which means it has one flat (plano) surface and one curved (convex) surface.
The lens's geometry is intricately designed, with a thickness of 2.3 mm at the edge and 4.9 mm at the center. The Effective Focal Length (EFL) of this lens is 40mm, making it suitable for a wide range of optical applications. The lens's curvature is defined by a radius of 20.672 mm on the curved surface, and the Back Focal Length (BFL) is 36.77 mm.
The L-PCX237 is made from the high-quality material N-BK7 Schott, a borosilicate glass known for its excellent optical properties. The lens is designed to work with a wavelength of 587.6 nm. The lens's coating is left unspecified, suggesting it may be uncoated. However, users should confirm this with the vendor or their sales representative.
