Fluke 075-CL 3 Inches (75 Millimeter) C-Range IR Window

If you are concerned about Arc-Flash but wish to continue with your infrared thermography program infrared windows are the answer. These Arc-Resistant, outdoor certified, infrared windows allow thermal, ultraviolet, visual and fusion technologies to be used without exposing personnel to live equipment.

All infrared windows from Hawk IR International use the unique Quadraband™ multispectral optic, allowing inspection with any camera for total flexibility both now and in the future.

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,
