This is the PLCX-25.4-103.0-C, a Plano-Convex Laser Grade Spherical Lens with a 25.4 mm diameter, manufactured by CVI Laser Optics. The lens is made of N-BK7 Schott, a popular material in the optical industry due to its excellent optical properties and high damage threshold.
The lens features a convex surface with a radius of curvature of 103.0 mm, and a plano surface on the other side. The center thickness of the lens is 4 mm, while the edge thickness is 3.2 mm. The effective focal length (EFL) of this lens is 200 mm, making it suitable for applications that require a long focal length.
The lens is uncoated, which means it does not have any anti-reflective coatings. While this may result in higher reflective losses, it also means that the lens can be used over a broad spectrum of wavelengths, from ultraviolet to infrared, without the risk of coating damage.
The item data also indicates that this lens is in stock and the vendor's website provides a detailed technical document for further information. This lens is a great choice for applications that require a high-quality, long focal length lens made of durable, optical-grade material.
