Many of the devices that one considers to be ultraviolet or visible optical components are also used in some temperature measurement and imaging devices.
|
| Suppliers of Temperature indicating devices that are based on the Thermochromic properties of certain materials, specifically, liquid crystals. Similar materials are very familiar as the displays on modern flat panels Television and computer displays as well as numerous electronic devices. The thermometers have been around much longer and are, for the most part, unpowered, passive devices that indicate temperature in a reflecting mode. They have been used for many years as advertising novelties or give-away thermometers for monitoring local ambient temperature, but there are other industrial and scientific devices availabe, also.
