Appl. No.:

09/725771

International Classification:

G01J 510

US Classification:

250372

Abstract:

A probe style radiometer includes a generally rectangular cross-sectional body and a probe having a square cross-section. The probe is preferably a hollow rod having a tip equipped with a UV-collecting aperture and a mirror. The mirror reflects UV light entering the aperture down the length of the rod to a detector in the body. A processor in the body then computes the amount of UV radiation based on signals from the detector. The amount may then be provided on a display integrated into the body. A ground quartz or glass window may be provided at the tip to seal the rod from exterior contamination and to diffuse the incoming UV radiation in a manner that will give the probe a near-cosine angular response. Filters within the radiometer body then filter this diffused radiation to the spectral region of interest. Preferably, the radiometer is battery powered and includes switches on the body to allow a user to control the mode of operation.

International Classification:

G01J 100

US Classification:

250372

Abstract:

An ultraviolet (UV) radiometer includes as one component a data collection unit which is sufficiently small that it can be placed in UV curing applications which have normally been inaccessible as another component a data reader into which the data collection unit is inserted for displaying and/or processing the actual data collected by the data collection unit during a process run. Because of its small size, the data collection unit makes it possible to obtain true process control in applications that could not previously be monitored. After making a dosage measurement, the data collection unit is inserted into the data reader to display the actual data collected during a UV curing run. After reading the data in the data collection unit, the data reader clears the previously stored data and resets the unit to take a new dosage reading.
