LA5714-E 25.4 mm Dia. CaF2 Plano-Convex Lens; EFL=200mm 2-5µm

The LA5714-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 200 mm, which is the distance from the lens's center to the focal point when the lens is imaging an object at infinity.

The LA5714-E has a front coating of tho ecaf2arc20005000, which is a broadband anti-reflection coating designed to reduce surface reflections and increase transmission. This coating is applied to both the front and back surfaces of the lens.

The lens has a thickness of 2 mm at the edge and 2.9 mm at the center. The front surface of the lens has a radius of curvature of 86.8 mm, while the back surface is planar. The lens does not have any inner or outer radii.

This lens is a Spherical lens, meaning it has a spherical surface. The curvature of the spherical surface helps to focus light, making this lens suitable for a wide range of optical applications.
