KPX615 25.4 mm Dia. x 350 mm FL; Uncoated; Plano-Convex Lens

The KPX615 is a Plano-Convex lens with a diameter of 25.4 mm and a focal length of 350 mm. This lens is sourced from MKS/Newport, a renowned vendor in the optical industry. 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 edge, and thickness center. The diameter is 25.4 mm, the thickness edge is 3 mm, and the thickness center is 3.45 mm. The effective focal length (EFL) is 350 mm, and the radius of curvature (R1) is 181.552 mm. The back focal length (BFL) is 347.73 mm, and the inner radius is 0 mm.

The lens is made of N-BK7 Schott, a popular optical glass due to its excellent optical properties and wide transparency range. The lens is designed to operate at a wavelength of 546.1 nm.

This lens is a Spherical lens, which means it has a surface that is a part of a sphere. The spherical shape is the simplest and most common type of lens used in optical systems.

Please note that the lens is uncoated, which means it may be more susceptible to environmental factors and may not perform as well in certain applications as coated lenses. However, uncoated lenses are often preferred for applications where cost is a significant factor.
