L-PCX374 90 mm Dia. Plano-Convex Lens; EFL=500mm Uncoated
The L-PCX374 is a 90 mm diameter Plano-Convex lens, designed and manufactured by Ross Optical. This lens boasts an effective focal length (EFL) of 500mm, making it suitable for a wide range of applications that require long focal lengths. The Plano-Convex design, where one side is flat and the other is curved, is a common type of spherical lens.
The lens's geometry is defined by its diameter, thickness at the edge, and thickness at the center. The diameter measures 90 mm, while the thickness at the edge is 2.3 mm and at the center is 6.2 mm. The radius of curvature of the curved surface is 258.4 mm, and the back focal length (BFL) is 495.87 mm. The lens does not have an inner or outer radius, indicating a symmetrical design.
The 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 587.6 nm. Notably, this lens does not have any coating, which may affect its performance in certain applications, particularly those requiring high transmission or resistance to environmental factors.
