This is a Plano-Convex lens, model PLCX-25.4-38.6-C, sourced from CVI Laser Optics. It is a spherical lens with a base shape of a circle, designed for use in laser applications. The lens has a diameter of 25.4 mm and a thickness at the edge of 3 mm, while the center thickness is 5.2 mm. The effective focal length (EFL) of this lens is 75 mm.
The lens is made of N-BK7 Schott glass, a popular material for laser applications due to its excellent optical properties. The lens is uncoated, meaning it does not have any additional layers to enhance its optical performance. However, it is still suitable for many applications, especially where cost-effectiveness is a priority.
The lens's radius of curvature is 38.6 mm, and it does not have any inner or outer radius specified, indicating a simple plano-convex design. The lens is designed to operate at a wavelength of 546.1 nm.
The lens is in stock and available for immediate purchase. More detailed information about this lens, including its full specifications, can be found in the provided datasheet.
