A new field-variable-focus infrared thermometry system, the VARIO-THERM, provides the first infrared thermometry (IRT) system capable of both varying the focus of the infrared temperature sensor and identifying the exact target area where a surface temperature measurement is being taken. This new optical system by Everest Interscience provides the first field-variable-focus 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 precision measurement.
As explained in Everest's 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."
With Everest's 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 field-variable-focus infrared sensor. Therefore, precision measurements can be obtained on the same target with variable spatial resolution.
The optical system of the field-variable-focus IRT system 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.
The invention of the field-variable-focus IRT system arose from a long-time need in the field of infrared thermometry. Other conventional infrared thermometers (IRT's) have been unable to precisely align the infrared sensor on the target and identify the exact target area being measured.
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. This problem is solved with the field-variable-focus IRT system.
With this new optical system, possibilities for new applications for infrared thermometers are endless. If you have a new application for infrared thermometry or want to solve an age-old problem with surface temperature measurement, please contact Everest Interscience.
And, if you plan to attend Sensors Expo & Conference in Rosemont, Chicago in June, 2008, you will be able to visit with Charles E. "Gene" Everest, Co-Owner and Design Engineer of Everest Interscience in person. Mr. Everest says, "I look forward to meeting you and discussing your applications for infrared thermometry with you.
