This is the PLCX-25.4-5151.0-C 25.4 mm Dia. N-BK7 Laser Grade Plano-Convex Lens, a high-quality optical component sourced from CVI Laser Optics. This lens is designed for use in laser applications and features a plano-convex geometry, making it ideal for focusing or collimating light.
The lens has a diameter of 25.4 mm and a thickness of 4 mm at the edge and center. It boasts an effective focal length (EFL) of 10000mm, which is the distance from the lens at which an object will be in focus. The lens is made from N-BK7 Schott glass, a popular material for laser applications due to its excellent optical properties and high damage threshold.
The lens is uncoated, meaning it does not have any additional layers applied to its surface to alter its optical properties. This can be beneficial in certain applications where a specific coating is not required or desired. However, it's important to note that uncoated lenses can be more susceptible to environmental factors such as dust and moisture, which can affect their performance.
