PLCX-25.4-25.8-C 25.4 mm Dia. N-BK7 Laser Grade Plano-Convex Lens; EFL=50mm Uncoated

This is the PLCX-25.4-25.8-C, a Plano-Convex Laser Grade Spherical Lens, sourced from CVI Laser Optics. The lens boasts a 25.4 mm diameter and is made from N-BK7 Schott, a popular material for its excellent optical properties and versatility. The lens has a center thickness of 5.3 mm and an edge thickness of 2 mm, providing a robust structure while maintaining a low profile.

The lens has a focal length (EFL) of 50 mm, making it suitable for a wide range of applications that require moderate magnification and focusing capabilities. The radius of curvature is 25.8 mm, and both the inner and outer radii are 0 mm, indicating a plano surface on one side and a curved surface on the other.

This lens is uncoated, meaning it does not have any additional layers to enhance its optical properties. However, this does not diminish its quality or performance. In fact, uncoated lenses can be advantageous in certain applications where specific reflective or transmissive properties are desired.

The lens is designed for a wavelength of 546.1 nm, a common wavelength used in various optical systems. It is important to note that the lens's performance can vary depending on the wavelength used, so it is crucial to consider this when selecting a lens for your application.
