11-707 25.4mm Diameter x 750mm FL; Uncoated; IR Ultrafast Thin PCX Lens

The 11-707 is a 25.4mm diameter, 750mm focal length, uncoated, infrared (IR) ultrafast thin PCX lens, available from Edmund Optics. This lens, with its plano-convex shape, is designed for use in the infrared spectrum, specifically at a wavelength of 587.6nm.

The lens's geometry includes a 1.37mm thickness at the edge and a 1.6mm thickness at the center. The inner radius is zero, and the outer radius is also zero, indicating a purely convex shape. The lens's effective focal length (EFL) is 750mm, and the back focal length (BFL) is 749.72mm. The radius of curvature (R1) is 344.25mm.

The lens is made from UVFS MAL-1965, a material specifically designed for use in the ultraviolet, visible, and shortwave infrared spectra. The lens is uncoated, which may affect its performance in certain applications, particularly those requiring high transmission or resistance to environmental factors.

This lens is suitable for use in a variety of applications, including but not limited to, IR imaging, spectroscopy, and beam shaping. However, due to its uncoated nature, it may not be ideal for applications requiring high contrast or where stray light could be a significant issue.

Please note that the lens's specifications are subject to change, and it is always a good idea to check the vendor's website for the most up-to-date and accurate information.
