11-710 25.4mm Diameter x 2000mm FL; Uncoated; IR Ultrafast Thin PCX Lens

The 11-710 is a 25.4mm diameter, 2000mm focal length plano-convex lens designed for use in the infrared spectrum. This lens, sourced from Edmund Optics, is uncoated and features a thin profile, making it an ideal choice for applications where space constraints are a concern.

The lens's geometry includes a 1.512mm thickness at the edge and a 1.6mm thickness at the center, with an effective focal length of 2000mm. The inner radius is 0, while the outer radius is also 0, indicating a planar surface on one side. The lens's radius of curvature is 918mm, and the back focal length is 2001.08mm.

The lens is made from UVFS Mal-1965, a material specifically designed for use in the ultraviolet, visible, and shortwave infrared spectra. The wavelength of operation for this lens is 587.6nm, placing it firmly in the infrared range.

Please note that this lens is uncoated, which may affect its performance in certain applications. Coatings can be used to reduce surface reflections, increase transmission, and protect the lens from environmental hazards. However, the lack of a coating on this lens may be beneficial in applications where the introduction of additional layers could cause unwanted distortions or reflections.
