The KPX196 is a Plano-Convex lens with a diameter of 50.8 mm and a focal length of 175 mm. This lens is sourced from MKS/Newport, a renowned vendor in the optical industry. The lens is uncoated, which means it does not have any additional layers to protect or enhance its optical properties.
The lens is made of N-BK7 Schott, a popular material in the optical industry due to its excellent optical properties and high damage threshold. The lens's geometry is characterized by a thickness of 3 mm at the edge and 6.64 mm at the center. The inner radius is 0, indicating a plano surface on one side and a curved surface on the other.
The lens's radius of curvature is 90.44 mm, and the back focal length is 170.62 mm. The effective focal length (EFL) is 175 mm. The wavelength for this lens is 589 nm.
This lens is ideal for applications that require a simple, high-quality lens with a long focal length. Its uncoated surface makes it suitable for use in environments where coated lenses may not be necessary or desirable. The lens's large diameter and long focal length make it suitable for use in a variety of optical systems, including beam expanders, telescopes, and other systems that require a long focal length.
