KPC070 50.8 mm Dia. x -200 mm FL; Uncoated; Plano-Concave Lens
The KPC070 is a Plano-Concave Lens, part of the Spherical Lens category, sourced from MKS/Newport. This lens boasts a diameter of 50.8 mm and a focal length of -200 mm, making it suitable for a wide range of optical applications.
The lens is made from N-BK7 Schott, a popular material in the optical industry due to its excellent optical properties and versatility. The lens is uncoated, which means it does not have any additional layers to enhance its optical performance or protect it from environmental factors. However, uncoated lenses can be a cost-effective solution for applications where such enhancements are not necessary.
The lens has a thickness of 5.06 mm at the edge and 2.5 mm at the center. The inner and outer radii are both 0, indicating a flat surface on one side and a concave surface on the other. The back focal length is -201.64 mm, slightly longer than the focal length due to the thickness of the lens.
This 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. The lens is in stock and available for immediate purchase, as indicated by its valid weblink status.
