Precise Characterization of Infrared Sources

The demand for IR measurement solutions has increased significantly in the recent years. IR LEDs and IR lasers such as VCSELs have enabled many new applications in the field of “IR sensing”, using the NIR range (800-1000 nm) but also higher wavelengths as 1380 nm. Measurement tasks range from 3D sensing (facial recognition, LiDAR and automotive in-cabin driver monitoring) to optical fingerprint sensors and healthcare monitoring.

Instrument Systems has developed a range of new products and offers now an extensive IR measurement portfolio for IR LEDs and laser sources as VCSEL. It allows analyzing the optical output (such as optical power, spectrum and pulse shape) of IR emitters under various electrical driving conditions (down to nanosecond pulses) and temperature control. In addition, camera-based measurement equipment for VCSEL measurement are obtainable.

The test systems for IR emitters from Instrument Systems are of modular design and individually tailored to the customer’s measurement tasks. This applies equally to the laboratory and automated production tests. Our application experts configure the system for all possible IR emitters, for measuring both narrowband sources such as laser diodes/VCSELs, LEDs and other broader-band emitters.

Our system solution consists of the following components: calibrated radiometric measuring equipment, optional power sources and temperature control for the DUT, and required software modules.

Their key features are:

• High modularity and measurement accuracy

• Broad spectral range (200–2150 nm)

• High spectral resolution (up to 0.09 nm)

• Calibration traceable to a national lab (PTB or NIST)

• Integration of temperature control and power sources for DUT

• Pulse generator and pulse measurement (down to µs pulses)
