This is a high-quality 39-472 25.4mm Dia. ZnSe Aspheric Lens, featuring an effective focal length (EFL) of 15mm and a numerical aperture (NA) of 0.85. The lens is sourced from the reputable vendor, Edmund Optics, and is uncoated.
The lens is designed with a circular base shape and a diameter of 25.4mm, making it suitable for a wide range of optical applications. It has a thickness of 1.89mm at the edge and 5.5mm at the center. The inner and outer radii are 0mm each, and the back focal length (BFL) is the same as the EFL, at 15mm.
The lens's aspheric shape is defined by its first and second radii (r1 and r2), which are 21.045mm and 0mm respectively. The lens's shape is further detailed by its conic constant (k1), which is -1.101191. The lens does not have any coating, as indicated by the empty 'coating' parameter in the item data.
The lens is designed to operate at a wavelength of 10600nm. It is important to note that the 'weblink status' is 'Valid - in stock', indicating that this lens is readily available for purchase and use.
