IR Measurement Fast and precise measurement of IR emitters as LEDs/ lasers
Modular test system with high measurement accuracy
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
- Required software modules
Key Features:
- High modularity and measurement accuracy
- Broad spectral range (200–1700 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)
Requirements
Accurate measurement of narrow-band emitters such as laser diodes/ VCSELs calls for spectrometers with a high spectral resolution. For this purpose, we offer the CAS-HR series that covers the NIR range and enables a spectral resolution of up to 0.09 nm. With pulsed IR emitters the speed of the measurement through the use of a fast photodiode is also critical. In contrast, a spectrometer with a wide spectral range is needed for the measurement of broader-band IR emitters.
For the characterization of IR emitters, the optical output must be measured with different electric currents and temperatures. Our IR measuring system thus offers the possibility of controlling various different power sources and temperature.
System configuration
A complete system for the characterization of IR emitters typically consists of the following components:
Individual configuration
Due to the diversity of products and optional accessories, this highly flexible system solution from Instrument Systems is ideal for the comprehensive measurement of IR emitters during the development process or in quality control.
