11-729 25.4mm Diameter x 2000mm FL; Uncoated; Ultrafast Thin PCX Lens

The 11-729 is a high-quality Spherical Lens (Plano-Convex) with a circular base shape, designed and manufactured by Edmund Optics. This lens boasts a 25.4mm diameter and a long focal length of 2000mm, making it suitable for applications requiring precise focusing and imaging over extended distances.

The lens is made from UVFS MAL-1965, a material specifically chosen for its optical properties. The material's refractive index and dispersion characteristics are well-suited for applications in the visible light spectrum, particularly at the specified wavelength of 587.6nm.

The lens has a thickness of 1.512mm at the edge, gradually increasing to 1.6mm at the center. This design ensures a thin, lightweight profile, enhancing its usability in various setups. The lens's inner and outer radii are 0, indicating a planar surface on one side and a convex surface on the other. The radius of curvature (R1) is 918mm, and the back focal length (BFL) is 2001.08mm.

Notably, this lens is uncoated, which means it does not have any anti-reflective or other surface coatings. While this may result in higher reflectance, it also means the lens is more versatile in terms of the wavelengths it can handle.

The lens's web link is valid and indicates it is in stock, making it readily available for immediate use. This lens is an excellent choice for users seeking a high-quality, ultrafast, thin PCX lens for their optical systems.
