KPX555 12.7 mm Dia. x 75.6 mm FL; Uncoated; Plano-Convex Lens

The KPX555 is a Plano-Convex lens with a diameter of 12.7 mm and a focal length of 75.6 mm. This lens is sourced from MKS/Newport, a reputable vendor in the optical industry. The lens is made of N-BK7 Schott, a popular material known for its excellent optical properties.

The lens geometry is characterized by its spherical shape, with a thickness of 3 mm at the edge and 3.51 mm at the center. The inner radius is 0, indicating a plano surface on one side and a curved surface on the other. The back focal length (BFL) is 73.28 mm, and the effective focal length (EFL) is 75.6 mm.

The KPX555 is uncoated, meaning it does not have any anti-reflective or other coatings. This can be advantageous in certain applications where the natural properties of the glass are desired, or where cost considerations are a factor. However, it's important to note that uncoated lenses can suffer from increased reflection, which may affect the performance in high-light applications.

The lens is designed to work with a wavelength of 546.1 nm, making it suitable for a wide range of applications in the visible light spectrum. It's ideal for use in optical systems that require a simple, high-quality lens with a long focal length.
