Coastal Optical Systems Inc. said its new CoastalOpt 60-mm UV-VIS-IR 1:4 apochromatic (apo) macro lens achieves a first in optical design as the first fully corrected lens for the UV-VIS-NIR (ultraviolet-visible-near infrared) spectrum.

The 60-mm UV-VIS-IR 1:4 apo macro provides full apochromatic correction over a broad waveband ranging from the onset of atmospheric ultraviolet transparency at 315 nm to the limit of CCD/CMOS sensitivity at 1100 nm in the infrared (IR), the company said.

Ordinary quartz-fluorite lenses cannot be color corrected into the infrared due to limitations inherent in these optical materials. According to Coastal Optical Systems, the 60-mm UV-VIS-IR 1:4 apo macro lens achieves unprecedented correction from UV through IR by combining fluorite and quartz with elements made from carefully selected high transmission glasses. An advanced floating element optical formula, including five elements made from calcium fluoride crystal, ensures stunning performance under all conditions. Ghosts and hotspots are eliminated by a combination of optical design and advanced ultrabroadband antireflective coatings.

The lens, the result of a technological partnership between Coastal Optical Systems and Caldwell Photographic Inc., is ideal for forensics, crime scene documentation, medicine, science, and fine art photography, said Coastal Optical Systems, a subsidiary of Jenoptik Laser, Optik, Systeme GmbH in Jena, Germany.
