KPX099 25.4 mm Dia. x 138 mm FL; Uncoated; Plano-Convex Lens

The KPX099 is a Plano-Convex lens with a diameter of 25.4 mm and a focal length of 138 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 known for its excellent optical properties.

The lens's geometry is characterized by a thickness of 3 mm at the edge and 4.136 mm at the center. The inner radius is 0 mm, indicating a plano surface on one side and a curved surface on the other. The radius of curvature of the curved surface is 71.583 mm, and the back focal length is 135.28 mm.

The KPX099 is an uncoated lens, meaning it does not have any anti-reflective or other coatings. This can be beneficial in certain applications where the natural properties of the glass are desired. However, it's important to note that uncoated lenses can suffer from reflective losses, which can be significant at higher angles of incidence.

The lens is designed to work at a wavelength of 546.1 nm. This wavelength falls within the visible spectrum, making the lens suitable for use in applications involving visible light.
