tinyTracker 172 nm: Band radiometer for precise measurements of 172 nm xenon excimer radiation
The tinyTracker 172 is a calibrated belt radiometer for irradiance and dose measurement on xenon excimer lamps at 172 nm. Its SiC photodetector is calibrated by PTB and sensitive from 155 nm to 520 nm, and the measuring range is 0–200 mW/cm². At a height of 10 mm the instrument travels through irradiation channels and records for up to three hours at 1 to 100 Hz – including under an inert gas atmosphere.
Xenon excimer lamps enable new, resource-saving and more efficient production possibilities. They are used in the field of surface treatment for matting, cleaning, surface activation or to reduce photoinitiator consumption.
For this purpose, the narrow-band spectrum around 172 nm is usually used to irradiate under inert gas conditions. Then the high photon energy is sufficient to split almost all organic compounds.
The measurement of 172 nm (VUV) is an important component for process control and optimization.
With the tinyTracker 172 we offer a calibrated band radiometer which is suitable for use in an inert atmosphere. The tinyTracker 172 is absolutely calibrated and measures the irradiance and irradiation dose of xenon excimer lamps directly at 172 nm.
Due to its particularly flat design, the tinyTracker 172 can be guided through the irradiation channels of UV belt dryers and other industrial equipment.
The recording of the values starts automatically when an adjustable minimum irradiance is exceeded. The built-in photodetector is calibrated by PTB.
Data is recorded on an exchangeable SD card and transferred via USB to PC.
Evaluation and data export are conveniently performed by the PC software for tinytracker 172.
The Li-Ion battery ensures a recording duration of up to 3 hours. The Li-ion battery can be charged directly via the USB interface. An additional power supply unit is included.
