KPX618 25.4 mm Dia. x 400 mm FL; Uncoated; Plano-Convex Lens

The KPX618 is a Plano-Convex lens with a diameter of 25.4 mm and a focal length of 400 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 is made of N-BK7 Schott, a popular material in the optical industry due to its excellent optical properties and wide transmission range. The geometry of the lens includes a thickness of 3 mm at the edge and 3.39 mm at the center. The lens's effective focal length (EFL) is 400 mm, and its radius of curvature (R1) is 207.488 mm. The back focal length (BFL) is 397.77 mm, and the inner radius is 0 mm.

This lens is designed for use with a wavelength of 546.1 nm. Its spherical shape ensures excellent light gathering and focusing capabilities. The lens is suitable for various applications, including imaging, beam shaping, and laser 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 high-intensity light applications as coated lenses. However, the uncoated feature can be beneficial in applications where a natural lens surface is required.
