KPC028 25.4 mm Dia. x -200 mm FL; Uncoated; Plano-Concave Lens
The KPC028 is a Plano-Concave Spherical Lens, sourced from the reputable vendor MKS/Newport. This lens boasts a diameter of 25.4 mm and a focal length of -200 mm, making it ideal for applications that require a negative focal length. 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's geometry is meticulously designed, with a thickness edge of 3.13 mm and a thickness center of 2.5 mm. The inner and outer radii are 0 mm, indicating a flat surface on both sides of the lens. The back focal length (BFL) is -201.64 mm, a value that is crucial in determining the lens's performance in a specific optical system.
The KPC028 is uncoated, meaning it does not have any additional layers to enhance its optical properties. This makes it suitable for applications where coating is not required or preferred. The lens is designed to work with a wavelength of 589 nm, a common wavelength used in various optical applications.
