Model 320 Data Sheet

Model 320

The Model 320
The Model 320 is a simplification of the Model 400. As in the 400, a built-in computer allows storing of sensor readings and calculations of average value and percent deviations. The two line display format allows for several readings at one time. The Model 320 measures MW/CM2, peak MW/CM2, MJ/CM2 (single pulse), accumulated MJ/CM2, time (single pulse), and accumulated seconds.

The Model 320 has four modes of operation. Mode 3 (MW/CM2) and Mode 4 (MJ/CM2) allow taking five readings in a fixed pattern and then displaying the average value and the +/-% uniformity as well as the +/-% deviation from the center value.

The rechargeable battery lasts for about 18 hours and the charger operates from 100-240 VAC, 50-60 Hz with UL, CE, and TUV approvals.

A variety of sensor packages can be used with the Model 320 at wavelengths from 220nm to 540nm and beyond. Traceability to NIST is +/-3.0% with probe matching to +/-1.0%. The Model 320 can be set up to work with a dual channel probe.

Sensor Spectral Ranges
This graph accurately represents the spectral response of probes used today in the Microelectronic Industry. This graph includes the spectral response of the detector as well as the spectral response of the filter glass used in probes.
