Description:  The Emerging Measurements Company LabKit enables principles of fluorescence decay to be measured and demonstrated.  The emission of a key thermographic phosphor (TP) - La2O2S: Eu - can be observed from 0 to 100 °C.   The standard LabKit is intended for university physics, chemistry, and engineering laboratories.  In the standard LabKit, a copper target is coated with a thin layer of phosphor and a thermocouple embedded in the copper target for temperature monitoring.  The copper target is in contact with a Peltier Heater/Cooler which may heat or cool the sample as desired. 

The LabKit can also act as an instrument for evaluating other TPs either onboard the LabKit  or by using an external light source such as a laser, laser diode or a light emitting diode (LED) if another excitation wavelength is required.   Another alternative is to use fiber optics to transport the excitation light to an external target and then transmitting the emission light back to the LabKit’s photomultiplier tube for analyzing the signal. By operating in this mode, the LabKit may be used to either calibrate an external phosphor sample or measure the temperature of an external target.
