KPC010 6.35 mm Dia. x -25 mm FL; Uncoated; Plano-Concave Lens

The KPC010 is a plano-concave lens with a diameter of 6.35 mm and a focal length of -25 mm, making it ideal for applications that require light to be focused or dispersed over a short distance. This lens is sourced from MKS/Newport, a reputable vendor known for their high-quality optical components.

The lens is made from N-BK7 Schott, a type of borosilicate glass that offers excellent optical performance and is widely used in various applications. The lens is uncoated, which means it does not have any additional layers to enhance its optical properties or protect it from environmental factors. This makes it suitable for applications where such coatings are not necessary or desirable.

The geometry of the lens includes a thickness of 2.82 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 -26.64 mm, which is the distance between the lens and the focal point when the lens is used in a converging setup.

The lens is designed to work with light of wavelength 589 nm. It is spherical in shape, which is the most common and versatile lens shape, offering good performance across a wide range of applications.
