Superior Uniformity and Speed
The unique cavity construction of the 4100 preserves the high emissivity of traditional cavity blackbody designs, but greatly

improves the uniformity and slew rate of the system. Cooling rates are markedly faster, significantly reducing test times.

High Accuracy and Repeatability
The microprocessor-based temperature controller is designed for optimum accuracy and stability. A high resolution enhanced

PID temperature servo provides zero drift and low jitter control of the emitting surface’s temperature.

Ease of Calibration
Calibration is fast and easy. All adjustments can be made directly from the front panel or through the remote interface.

Calibration points are independent of each other, allowing the user to touch up a single calibration point.
