KPC079 50.8 mm Dia. x -75 mm FL; Uncoated; Plano-Concave Lens

The KPC079 is a plano-concave lens with a diameter of 50.8 mm and a focal length of -75 mm, sourced from MKS/Newport. This uncoated lens is made of N-BK7 Schott, a popular material in the optical industry due to its excellent optical properties and wide transparency range.

The lens's geometry includes a thickness edge of 9.96 mm and a thickness center of 2.5 mm, providing a slim profile suitable for various applications. 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 (BFL) is -76.64 mm, and the effective focal length (EFL) is -75 mm.

The KPC079 is designed for use with a wavelength of 589 nm, making it suitable for applications that use this wavelength, such as sodium vapor lamps. Its spherical shape allows for efficient light bending, making it ideal for use in imaging systems, beam shaping, and other applications where light manipulation is required.

Please note that this lens is uncoated, which may affect its performance in certain applications, particularly those involving high-intensity light sources or specific wavelength ranges. However, uncoated lenses can be more cost-effective and are often sufficient for many applications.
