The HawkEye IR-6x Series is a MEMS technology pulsable infrared emitter. This source is based on patented technology, utilizing a thin film resistor of diamond-like nanostructured amorphous carbon. Due to its low thermal mass, the IR-6x Series can be pulsed at frequencies up to 70+ hertz with good modulation depth (contrast between the on and off states).

Operational Characteristics for the IR-6x Series

Active Area	2.2 mm x 2.2 mm
Resistance	45 ohms (nominal) in the hot state
Typical Operating Temperature	450°C to 750°C
Drive Voltage at 750°C	6.7 volts +/- 0.4 volts
Frequency at 50% Modulation Depth (25% Duty Cycle)	70 hertz
Spectral Range	1 to 20 microns
Emissivity	0.8 in the 2 to 14 micron range
Output	25-30% greater than the IR-50 (see the Spectral Emission Chart)

Typical Operating Parameters

	Typical Levels
Temperature	450	600	750	degrees centigrade
Voltage	4.0	5.5	6.7	Volts (AC or DC)
Current	89	122	149	mAmps
Power Input	0.36	0.67	1.00	Watts
Estimated Life	100,000	40,000	5,000	hours of operation (10 hertz at 50% duty cycle)

NOTE: The operating parameters assume an infrared source operating without a radiator and at ambient temperature and pressure. A rectangular voltage pulsed at a frequency of 10 hertz and with a duty cycle of 50% is used for heating. If a longer duty cycle (or steady-state operation) is used, lower power levels are recommended in order to achieve the desired temperature. Also, proportionately shorter lifetime would be expected.
