Alexandrite Effect
Spectropyrometer
Alexandrite effect spectropyrometer (US Patents 7,004,624 and 7,052,177)
The alexandrite effect spectropyrometer measures the relative
spectral power distribution of a radiating body in the wavelength range of 380 -
760 nm, integrates the relative spectral power distribution in the wavelength
range, and determines its thermal temperature by the patented methods. It can
directly measure high to ultrahigh temperature from 800 K to 100,000 K of any
radiating bodies, such as blackbody, gray bodes, combustion chambers, gas
turbines, plasma jets, flames, electric arcs and
discharges, furnaces, metals and ceramics etc. At present, the spectropyrometer is
the only instrument that can directly measure temperature over 4000 K. The
spectropyrometer can directly measure high to ultrahigh thermal temperature
of plasma jets, electric arcs and discharges, and high temperature flames up to
100,000 K. The spectropyrometer is robust to very demanding working
environments.
The alexandrite effect spectropyrometer has a spectral
correction function, a sequential temperature measurement function, and a
temperature output port. The spectral correction function can be used to
correct spectra for accurate temperature measurement of the targets with
spectral lines and/or background noise. The sequential temperature
measurement function can be used to measure a target continuously with a
time interval as short as 10 ms, and the measured temperatures and spectra
are saved for industrial applications and spectroscopy study. By using the
sequential temperature measurement function, the spectropyrometer can
measure a temperature distribution by one measurement, and can measure
temperature of a target emitting radiation in a very short time, such as an
electric discharge. The temperature output port is compatible with other
industrial and scientific equipment for temperature control and other
purposes. The spectropyrometer can also continuously outputs spectra to
monitor a target for determining whether a processing is normal or a
criterion is over limit.
The alexandrite effect spectropyrometer is awarded two
U.S. patents 7,004,624 and 7,052,177.
