LA5464-E 25.4 mm Dia. CaF2 Plano-Convex Lens; EFL=500mm 2-5µm

The LA5464-E is a Plano-Convex lens with a diameter of 25.4 mm, designed for use in the 2-5 µm wavelength range. This lens is sourced from Thorlabs, a reputable vendor known for its high-quality optical components.

The lens is made of Calcium Fluoride (CaF2), a material with a high transmission range in the infrared spectrum, making it ideal for applications in this range. The lens has an effective focal length (EFL) of 500mm, providing a focused beam for various optical systems.

The LA5464-E features a plano-convex geometry, where one side of the lens is flat, and the other side is curved. This design allows for efficient light collection and transmission, making it suitable for use in imaging systems, spectroscopy, and other applications where high-quality optical performance is required.

The lens has a thickness of 2 mm at the edge and 2.4 mm at the center, providing structural rigidity while maintaining a low profile. The front and back surfaces of the lens are coated with Thorlabs' ECaF2ARC20005000 coating, which enhances the lens's transmission in the 2-5 µm range and provides protection against environmental contaminants.
