Color Analysis
Visible microspectrophotometry (MSP) is used to
measure the visible spectrum of a material in either transmitted or
reflected light, or the emission of light from a sample in the case
of fluorescence or cathodoluminescence.
In forensic science, MSP is most commonly used to
measure and compare the color of fibers. Using a microscope
attachment, color can be measured and compared on regions of fibers
that approach the wavelengths of visible light.
The CRAIC system shown here is one of two such
systems owned by Microtrace. This system is built with quartz
optics to permit UV microspectroscopy, is equipped with halogen,
xenon and mercury illumination to allow for fluorescence
Microspectroscopy (microfluorimetry), and is equipped with an
ultraviolet camera for imaging specimens in the ultraviolet region
of the spectrum.
Micro-Colorimetry
Using micrometer scale path lengths, solution
concentrations can be calibrated and measured on micro-liter scale
samples.
