KPX122 25.4 mm Dia. x 850 mm FL; Uncoated; Plano-Convex Lens
The KPX122 is a Plano-Convex lens with a diameter of 25.4 mm and a focal length of 850 mm. This lens is sourced from MKS/Newport, a renowned vendor in the optical industry. The lens is made of N-BK7 Schott, a popular material in the field due to its excellent optical properties.
The lens's geometry is characterized by a thickness of 3 mm at the edge and 3.183 mm at the center. The inner radius is 0, indicating a plano surface on one side and a curved surface on the other. The radius of curvature of the curved surface is 440.912 mm, and the back focal length is 847.9 mm. The effective focal length (EFL) is the same as the focal length, at 850 mm.
This lens is uncoated, meaning it does not have any anti-reflective or other coatings. While coatings can enhance the performance of a lens in certain applications, an uncoated lens can be suitable for applications where such enhancements are not necessary.
The lens is designed to work with a wavelength of 546.1 nm, a common reference wavelength in optical systems. It is important to note that the performance of the lens can vary depending on the wavelength of the light it is intended to focus.
