infrared microscope

[¦in·frə¦red ′mī·krə‚skōp]
(optics)
A type of reflecting microscope which uses radiation of wavelengths greater than 700 nanometers and is used to reveal detail in materials that are opaque to light, such as molybdenum, wood, corals, and many red-dyed materials.

Colleti of the Chemistry Department at University of Western Australia for instructions and help with DRIFT measurements, Mr Peter Chapman of the School of Applied Chemistry Department, Curtin University of Technology, for instructions on use of the infrared microscope, and Dr Richard Harper for valuable discussions of the results.
Infrared chemical images from the film were collected in transmittance also at 4 [cm.sup.-1] spectral resolution using a 64 by 64 pixel focal-plane array (FPA) detector on the same infrared microscope. The resulting chemical images are shown in Figure 3, where each image represents the integration of absorption bands across the full image.
The corresponding infrared spectra were collected using a Hyperion infrared microscope (Bruker Optics, Inc.) and are shown in Figure 2.
The Thermo Scientific Nicolet iN10 MX infrared microscope from Thermo Fisher Scientific, Madison, Wisc., does not require any special training in microscopy or spectroscopy or special attachments.
The present system is attached to an infrared microscope, Bruker Hyperion 1000, which allows for inspection of spatially isolated points of a sample and is useful when characterizing homogeneous thin films or optical materials.
Sample viewing is a significant source of frustration in the operation of an infrared microscope. On the new FTIR microscopes, sample viewing is obtained through color CCD digital video imaging, providing a more comfortable experience with an export option to send the image to a second monitor connected to the personal computer.
Theoretically it can be shown that the spatial resolution of an infrared microscope using a single aperture is given by 2.0 [lambda] where [lambda] is the wavelength and NA is the numerical aperture of the lens.
Other automated systems include the AIM-8800 infrared microscope and AIM View software, the AccuSpot system for fractioning separated samples, and automatic pipetting, according to Kevin McLaughlin, Shimadzu's senior marketing communications coordinator, Columbia, Md.
