Fluke 075-CLKT - C-Range Infrared Window Kwik Twist

Why is available area important?

Understanding the difference between “Optic Diameter” and “Available Area” gives the thermographer a measure of how much infrared energy is passing through the window. The more energy, the better the reading. Using a crystal IR Window means that the entire area is available for infrared transmission for optimum repeatability and results. While a mesh grid may have a larger “Optic Diameter” the grid itself blocks the IR signal, meaning that the amount of radiation available to the camera is significantly reduced and the signal may be irregular. It is a generally accepted fact that due to interference by mesh grids, transmission correction and hence measurement is not possible,

With a Kwik Twist cover that magnetically sticks to the panel when removed, Fluke IR Windows are easy to use and deliver unmatched image clarity through a CLIRVU® crystal. Exclusive to Fluke IR Windows, CLIRVU crystal technology is impervious to both moisture and vibration. CLIRVU crystals are designed to withstand the extreme pressures and temperatures of an arc-fault event, and offer protection from molten projectiles associated with arc-flashes.
