Everest Interscience now offers their
field-variable-focus (Vario-Zooom™)
infrared thermometers,
that provides the first infrared thermometry (IRT) system capable of identifying
the exact target area where a surface temperature measurement is being taken.
As explained in
U. S. Patent No. 7,355,178, it has “… a field-variable-focus optical system
for producing a detector image on a target surface at various working
distances.’ The exact location and dimensions of the target area under test are
precisely identified. The patent goes on to explain that “…the system can
perform errorless measurements of targets located at variable distances from the
thermometer.”
The invention
of the Vario-Zooom™ arose from a long-time need in the field of infrared
thermometry. Other conventional infrared thermometers (IRTs) have been unable to precisely
align the infrared sensor on the target and identify the exact target area being
measured. The new optical system by Everest provides the first IRT system
capable of visible identification of the target area. This is required for an
accurate optical alignment between the IRT and the target for precise
measurement.
It is well
known in the industry that infrared surface temperature measurement reading errors can result from improper alignment of
the IRT with the target. When the optical system of the infrared thermometer is
not pointing directly at the target, the detector collects energy coming from
the target and the background, thereby providing an erroneous reading. What’s
more, since the infrared beam is not visible to the human eye, the alignment of
the IRT with the target cannot be visually controlled with conventional infrared sensors.
The optical
system of the field-variable-focus IRT also includes a baffle for reducing
background radiation received from sources other than the target. Since the
infrared sensor reads the surface temperature of the first object it “sees,”
this is vitally important if an operator is to receive a true reading of the
target.
With
Everest’s TTL/SLR Intra-Optical Through-The-Lens
targeting system, the exact location and dimensions of the target area under
test are precisely identified. This is true not only under static conditions
but also under variable imaging conditions, which may result when re-focusing
the infrared sensor. Therefore, according to U. S. Patent No. 7,355,178, the
new optical system by Everest,”… can perform errorless measurements of targets
located at variable distances from the IRT.” And these same precision
measurements can be obtained on the same target with variable spatial
resolution.
With this new optical system,
possibilities for new applications for infrared thermometers are endless. If
you have a new application for infrared
thermometry and want to get an infrared sensor to market to fulfill this
need, please contact Everest Interscience. We can discuss the possibility of licensing this new
technology or designing an instrument for you that will get your product to
market in weeks instead of months.
