Natural Science Forum / Physics / Research / November 2007Ir sensor
Hi everyone I am heating a surface with a 10.6nm laser and i want to measure the temperature of this surface. Is there a sensor that can give me a real time measurement? If you can help me, please give me link or help me to understand what i am doing rung. I know that the ir and the laser are in the same bend but still i need to know the temp. with gratitude gon diet > Hi everyone > [quoted text clipped - 5 lines] > I know that the ir and the laser are in the same bend but still i need > to know the temp. How hot compared to ambient? "Infrared camera" 931,000 hits IR ear thermometers. A standard videocam sees into the near-IR. All it requires is a visible cut-off filter.

J. Wallace > Hi everyone > [quoted text clipped - 8 lines] > with gratitude > gon diet I would have thought that what you wanted was an interference filter and a thermal imager. The 12.6 micron would be cut out. Also what about a 3-5 micron imager? A Pyro is cheaper is cheaper than a 3-5 but you will need a filter. - Ian Parker |
