KPX546 12.7 mm Diameter x 38.1 mm FL Uncoated Plano-Convex Lens
The KPX546 is a Plano-Convex lens with a 12.7 mm diameter and a focal length of 38.1 mm. This lens is sourced from MKS/Newport, a renowned vendor in the optical industry. The lens is made of N-BK7 Schott, a popular material for optical elements due to its excellent optical properties and wide transparency range.
The lens's geometry is characterized by its diameter, thickness, and radii. The diameter is 12.7 mm, and the edge thickness is 3 mm, while the center thickness is 4.05 mm. The lens's radius of curvature (R1) is 19.69 mm, and the back focal length (BFL) is 35.42 mm. The lens's effective focal length (EFL) is 38.1 mm, which is the distance from the lens's principal plane to the focal point.
The lens is uncoated, which means it does not have any anti-reflective or other coatings. This can be advantageous in certain applications where the uncoated surface properties are desirable. However, it's important to note that uncoated lenses can have higher reflectivity, which can lead to losses in certain applications.
The lens is designed to work at a wavelength of 546.1 nm. This wavelength falls within the visible spectrum, making this lens suitable for applications in the visible range.
