11-701 25.4mm Diameter x 250mm FL; Uncoated; IR Ultrafast Thin PCX Lens
The 11-701 is a 25.4mm diameter, 250mm focal length plano-convex lens designed for use in the infrared spectrum. This lens is sourced from Edmund Optics and is currently in stock, as indicated by its weblink status.
The lens's geometry is characterized by a 0.9mm thickness at the edge and a 1.6mm thickness at the center. It boasts an effective focal length (EFL) of 250mm and a radius of curvature (R1) of 114.75mm. The back focal length (BFL) measures 249.18mm, and both the inner and outer radii are 0.mm, indicating a planar surface on the opposite side of the convex face.
The lens is made from UVFS MAL-1965, a material specifically designed for use in the ultraviolet, visible, and shortwave infrared spectra. The wavelength for this lens is 587.6nm. The lens is uncoated, which may affect its performance in certain applications, particularly those requiring high transmission or resistance to environmental factors.
Please note that this lens is spherical in shape, which may introduce some optical aberrations, particularly at wider apertures. However, its thin design and high-quality construction make it a suitable choice for many applications in the infrared spectrum.
