High-Speed Infrared Emitter with Integrated Drive Electronics

Key Features:

The high-performance PIRE

to be used as fast pulsed sources of blackbody

radiation. The solution can be ordered in a 3 item kit

including driver PCB assembly, emitter, and heat

sink or in an easily to use evaluation module. The

high-speed

pulsable

foil

emitter

with

its

corresponding drive electronics on a compact 14 pin

circuit board are designed to maximize output power

from 1 Hz to 200 Hz pulse speeds with a single

analog

control

input.

The

complementary

assemblies enhance signal to noise performance

while minimizing the overall system footprint.

The construction and implementation of the emitter

and control circuitry optimize performance by

matching the drive waveform for the desired

operating frequency.

This ensures peak output

temperatures at all pulse frequencies and promotes

the highest output for any application. Combined

with Opto Diode’s IR detectors, the PIRE

PLUS

solution operating with typical pulse speeds of 180

Hz and 50% modulation depth can accurately detect

trace elements in concentrations in low parts per

million.

The radiating element in the pulsable emitter is an

ultra-thin Opto Diode specific comb metallic foil

configured so that radiation from both sides of the

heated foil is efficiently directed out of the package

along the optic axis. The foil material has a typical

emissivity of 0.88 and closely emulates a blackbody

source in spectral distribution. The emitter is

designed to operate at a rated maximum foil

temperature of 1000 Kelvin. The emitter is offered in

a hermetically sealed TO-5 package with integral

standard parabolic reflector to provide near

collimated and uniform radiation output.

The PIRE

variety of applications.

The control circuitry will

exploit the capabilities of the high-speed source in

many applications. With the emitter, heat sink, and

controller set, designers can focus on maximizing

the

overall

system

performance

rather

than

interfacing with the source.
