The UV-visible-NIR
microspectrophotometer is
an instrument used to
measure spectra of
microscopic samples or
microscopic areas on samples.
They have many functions and are known by many names:
While some
have a specific function,
such as the
microfluorometer or the
Raman microspectrometer,
most are designed to measure
spectra of microscopic
areas or microscopic samples. The
UV-visible-NIR
microspectrophotometer
can be configured to
measure the transmittance,
absorbance, reflectance,
polarization,
fluorescence and
luminescence
microspectra of sample areas
smaller than a micron.
They are also
capable of non-destructive
and non-contact colorimetry
and thin film thickness
measurement.
Because UV-visible-NIR
microspectrometers are so
flexible, they are
used in many
fields of research and
industry.
Some of these instrument are
designed to be added to
standard microscopes or
probe stations, such as the
QDI
302™ microscope
spectrophotometer, while
others are fully integrated,
purpose built instruments
such as the
QDI
2010™ microspectrophotometer.
As such,
microspectrophotometers have
greater spectral ranges,
better results and a number
of features that are not
possible with add-on units.

The microspectrophotometer
allows the scientist or
engineer
to acquire spectra of
extremely small sample areas
non-destructively and
without touching the sample.
Measurements can be made
while light is transmitted
through the sample,
reflected from it or even
when the sample is made to
emit light, such as from an
OLED pixel. The
UV-visible-NIR range is
especially important as more
substances...even colorless
ones...absorb in the UV than
in the visible and infrared
regions. Therefore, a
UV microscope spectrometer
is very useful for
qualitative and quantitative analysis
of most samples for any
application.
Microspectrophotometers are
widely used in many
different fields and
can be found in both scientific
laboratories and production
facilities.
In the production
environment, for example,
they are used for quality
control of everything from
color masks in flat panel displays to the thickness of films on semiconductor
integrated circuits to
contamination monitoring on
hard disks.
Microspectrometers are used by analytical laboratories to identify and quantify microscopic
samples ranging from the
kinetics of cells by a biologist, diagnosis of cancer by a doctor, matching fibers
or paints by a forensic chemist, the qualification of gems or coal by a geologist, the determination of the color of ink or paint by a process chemist or even the analysis of great works of art by conservators.
As such, the
microspectrometer is a
highly flexible instrument
with many different
applications.
