What is a Light Current Voltage (LIV) Test?
A light-current-voltage (LIV) test is one of the essential tests that a laser diode must go through to ensure its reliability for post production use. This test will help to verify the operating characteristics of your laser device. The test works by driving current to your laser diode and measuring the resulting voltage and light output. The results are then plotted into a graph, which is known as an “LIV curve”.
Measure light and voltage output of laser devices
Tests up to 32 laser devices
Can be used as a benchtop or in rack system
User friendly software
Easily set and edit test parameters
Tests TO-56 and Chip on Carrier, VCSEL's and custom packages
Video Overview
SOFTWARE
User friendly GUI
Easily set and edit the starting current, maximum current, temperature, step delay and step size of the LIV measrements on the user friendly touch screen software.
Easily Edit Test Settings
This screenshot shows the test settings editor. In this example you may choose the Source Drive Parameters for each specific device and specific channels on a device, as required.
Alarms and safety feature
The software comes with many safety features. It will run a low current to the laser device to ensure that all connectors are in place and that your full test is safe to run.
Test Results
Results for all devices will be shown on a graph. Alternatively, you can choose to view the individual results of each laser device. This image represents the voltage and current characteristics of the laser device. Other results such as LIV can also be plotted.
All results can then be saved as a txt file and sent to the Y1000L Burn-in system.
