Lab Kit Description

Description: The Emerging Measurements Company LabKitenables principles of fluorescence decay to be measured anddemonstrated. The emission of a key thermographic phosphor (TP)-La2O2S: Eu-can be observed from 0 to 100 °C. The standardLabKitis intended for university physics, chemistry, and engineeringlaboratories. In the standard LabKit, a copper target is coated witha thin layer of phosphor and a thermocouple embedded in the coppertarget for temperature monitoring. The copper target is in contactwith a Peltier Heater/Cooler which may heat or cool the sample asdesired.The LabKit can also act as an instrument for evaluating other TPseither onboard the LabKit or by using an external light source suchas a laser, laser diode or a light emitting diode (LED) if anotherexcitation wavelength is required. Another alternative is to use fiberoptics to transport the excitation light to an external target and thentransmitting the emission light back to the LabKit’s photomultipliertube for analyzing the signal. By operating in this mode, the LabKitmay be used to either calibrate an external phosphor sample ormeasure the temperature of an external target.
