The L-PCX289 is a 50 mm diameter Plano-Convex lens, part of the extensive catalog offered by Ross Optical. This lens is designed for use in optical systems requiring a focal length of 150mm, as indicated by its Effective Focal Length (EFL) value. The Plano-Convex design, where one side is flat and the other is curved, is a common choice in optical systems due to its simplicity and versatility.
The lens's geometry includes a thickness of 1.9mm at the edge and 6mm at the center. The radius of curvature (R1) is 77.52mm, and the back focal length (BFL) is 146.05mm. The lens is made from N-BK7 Schott, a popular optical glass due to its excellent optical properties and wide transparency range.
Notably, this lens is uncoated. While coatings can enhance the performance of lenses by reducing reflections, increasing transmission, and protecting the surface, an uncoated lens can be a cost-effective choice when such enhancements are not required or when the user prefers to apply their own coating.
This lens is currently in stock and more information can be found on the Ross Optical website.
