11-695 12.7mm Diameter x 125mm FL; Uncoated; IR Ultrafast Thin PCX Lens
The 11-695 is a 12.7mm diameter, 125mm focal length plano-convex lens designed for use in the infrared spectrum. This lens, sourced from Edmund Optics, is uncoated and features a thin PCX design, making it an ideal choice for ultrafast applications.
The lens's geometry includes a 1.15mm edge thickness and a 1.5mm center thickness, with a 57.38mm radius on the curved surface. The back focal length measures 124.12mm, and the lens has no inner or outer radius specified, indicating a planar surface on the opposite side.
The lens is made from UVFS Mal-1965 material, optimized for a wavelength of 587.6nm. It is spherical in shape, and as mentioned, it is uncoated. This lack of coating can be beneficial in certain applications where the introduction of additional reflective layers may interfere with performance. However, it's important to note that uncoated lenses can be more susceptible to surface reflections and may require additional considerations for anti-reflection.
