Close up and personal - Coastal Optical Systems have announced the launch of the CoastalOpt 60mm UV-VIS-IR 1:4 Apo Macro lens.
Coastal Optical Systems Inc. are pleased to introduce the new CoastalOpt 60mm UV-VIS-IR 1:4 Apo Macro lens.
A first in optical design, the 60mm UV-VIS-IR 1:4 Apo Macro provides full apochromatic correction over an extraordinarily broad waveband ranging from the onset of atmospheric ultraviolet transparency at 315nm to the limit of CCD/CMOS sensitivity at 1100nm in the infrared.
Ordinary quartz-fluorite lenses cannot be colour corrected into the infrared due to limitations inherent in these optical materials. The 60mm 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 ultra-broadband AR coatings.
The product of a technological partnership between Coastal Optical Systems and Caldwell Photographic Inc., this lens is ideal for forensics, crime scene documentation, medicine, science, and fine art photography.
