The HawkEye IR-5x 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-5x Series can be pulsed at frequencies up to 100+ hertz
with good modulation depth (contrast between the on and off states).
This source is significantly better, watt for watt and
hertz for hertz than any competing non-mechanical modulation that technology
offers!

The key to Faster Electrical Modulation Lies
in the Cooling Time Constant
--- The HawkEye IR-5x Series is Faster than Competing Sources

The normal working range for the IR-50 Series Source is
450°C to 750°C. Peak short-term heating up to 850°C is possible. Calculated life is approximately
25,000 hours when operated at 600°C
and 10 hertz frequency. The input power required for this source is less than 1
watt.

Note that as frequencies are increased, voltage will need to be
increased in order to maintain a given temperature. See the IR-5x
Operational Guidelines for the voltage ratio.

The IR-5x Series is available in
three formats, all using the same MEMS technology pulsable infrared emitter:
-
The
IR-50
-
The
IR-55
-
The
IR-56
Each
is described in detail on the following pages.

The
IR-50, mounted in a TO-5 base with a
windowless cap provides the smallest package and gives the widest output energy
beam. FWHM (full width at half max) for the IR-50 is 100°, as demonstrated in
the Normalized Angular Output Chart below.
|
|
|
IR-50
|
|
|
|
The IR-55 utilizes a collimated HawkEye Optic
to provide more than 12x the on-axis output. The package is 0.5 inches in
diameter and 0.65 inches long. FWHM (full width at half max) for the IR-55 is
15°. See the Normalized Angular Output Chart below. The combination of fast electrical modulation,
low input power requirements and great on-axis output places this unit clearly
in a class of its own!

The IR-56
is built upon the same technology as the IR-55, but has
just 36% of the IR-55 size. The package is 0.4 inches in diameter and 0.36
inches long. And yet it delivers 50% to 75% of the IR-55 on-axis output energy. FWHM (full width at half max) for the
IR-56 is 20°. See the Normalized Angular Output Chart below.
