KPX076 25.4 mm Dia. x 25.4 mm FL; Uncoated; Plano-Convex Lens

The KPX076 is a Plano-Convex lens with a diameter of 25.4 mm and a focal length of 25.4 mm, making it a versatile choice for various optical applications. This lens is sourced from the reputable vendor MKS/Newport, ensuring high quality and reliability.

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 Plano-Convex geometry, where one side is flat and the other is curved, allows for efficient light convergence.

The geometry of the lens includes a thickness of 3 mm at the edge and 12.807 mm at the center. The inner radius is 0, and the lens has a back focal length of 16.95 mm. The effective focal length (EFL) is 25.4 mm, which is the same as the focal length, indicating that the lens is a thin lens.

This lens is uncoated, which means it does not have any anti-reflective or other coatings. While this may result in higher reflective losses, it also means that the lens is more cost-effective and suitable for applications where such coatings are not necessary.

The lens is designed to work with a wavelength of 589 nm, making it suitable for applications that use this wavelength, such as sodium vapor lamps. However, it can also be used with other wavelengths, although the performance may vary.
