Near-Infrared and Visible Spectrum Imaging
To date, most automated imaging has been done in the visible spectrum,
e.g. white light comprised of red, green, blue light (656nm to 486nm).
However imaging can be effectively executed outside the visible
spectrum, such as in the ultraviolet and the infrared spectra.
Non-visible light can realize several key advantages over white-light
applications. For example, infra-red viewing can be used to see thermal
variations or through-substrate imaging.
Near-infrared viewing (~700 to 2000n m) can be used to look into
otherwise opaque material such as Silicon. Silicon is used as a
substrate in wafer manufacturing, when such wafers have integrated
circuits written onto them it is desirable to view the IC through the
silicon. Near infrared viewing enables such examination.
Qioptiq Imaging Solutions has introduced a Near-infrared zoom version of our popular
Zoom 70XL platform, combining the exceptional optomechanical durability
with imaging capabilities in the 600-2000nm wavelength. By correcting to
the 600nm wavelength regime, red-orange light can be used to guide a
viewer in imaging visible and near-IR wavelengths simultaneously.
