KPX106 25.4 mm Dia. x 200 mm FL; Uncoated; Plano-Convex Lens
The KPX106 is a Plano-Convex lens with a diameter of 25.4 mm and a focal length of 200 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 3.783 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 103.36 mm, and the back focal length is 197.5 mm. The effective focal length (EFL) is the same as the focal length, at 200 mm.
This lens is uncoated, meaning it does not have any anti-reflective or other coatings applied to its surfaces. While this may result in higher reflective losses, it also means the lens is more versatile in terms of the wavelengths it can handle, as it is not optimized for any specific range.
The lens is designed to work with a wavelength of 589 nm, making it suitable for applications that use this wavelength, such as certain types of lasers or spectroscopy. The lens's shape is spherical, which is a common choice due to its ease of manufacturing and good optical performance.
