The leader in In-situ and In-line monitoring of semiconductor processes for more than 20 years


Accurate in-situ blackbody calibration source

The SR-72 is an accurate, high uniformity tool for in-chamber pyrometer calibration. 
Its design benefits from CI Systems’ 25 years of experience in blackbody design. 
The result is a highly accurate, stable, and reliable calibration source . 

The SR-72 can be pre-set to any given temperature set point through its front panel or through a RS232 serial port. Warm-up and cool-down time is exceptionally short, which minimizes tool downtime. The compact dimensions of the SR-72 allow it to fit into any available chamber, and it is lightweight enough to be easily carried along the production line.
