CAPX11 25.4 mm Dia. x 50.0 mm FL; Uncoated; Plano-Convex Lens

The CAPX11 25.4 mm Dia. x 50.0 mm FL is a Plano-Convex lens, a type of spherical lens, sourced from the reputable vendor MKS/Newport. This lens, with its base shape being circular, is designed for use in various optical applications.

The lens has a diameter of 25.4 mm and a thickness at the edge of 1.5 mm. The center thickness is 5.11 mm, providing a robust structure for optical systems. The effective focal length (EFL) of this lens is 50 mm, making it suitable for applications that require a longer focal length.

The lens's inner radius is 0, indicating a plano surface on one side and a curved surface on the other. The curvature of the lens is defined by a radius of 20.912 mm. This curvature, combined with the lens's material, influences the way light passes through it, affecting the optical system's performance.

The lens is made of CAF2 (Calcium Fluoride) material with the Mal-1963 specification. This material is chosen for its excellent optical properties, including high transmission in the infrared region, making it ideal for applications in this spectrum.

The wavelength of this lens is 2940 nm, further emphasizing its suitability for infrared applications. The lens is uncoated, meaning it does not have any additional layers to enhance its optical properties. However, uncoated lenses can be advantageous in certain applications due to their lower cost and simpler manufacturing process.
