The KPX636 is a Plano-Convex lens with a diameter of 25.4 mm and a focal length of 1000 mm. This lens is sourced from MKS/Newport, a reputable vendor in the optical industry. The lens is made of N-BK7 Schott, a popular material for optical elements due to its excellent optical properties.
The lens geometry is characterized by a thickness of 3 mm at the edge and 3.16 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 518.72 mm, and the back focal length is 997.92 mm. The effective focal length (EFL) is the same as the focal length, at 1000 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 by reducing reflections, increasing transmission, or providing other benefits, an uncoated lens can be a suitable choice for certain applications, such as when cost or simplicity is a primary concern.
The lens is designed for use 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.
