250 mA Laser Diode LIV System

Product Overview:

The LIV110 is a powerful test instrument for use in the lab and in production environments. This instrument is ideal for laser diode characterization, quality control of incoming goods and for OEM applications. This compact unit comprises the current source as well as the data acquisition and communication hardware. The LIV110 supplies a laser diode with well defined currents in the form of a staircase. During the current sweep, the instrument measures the optical power of the laser diode (L), the drive current (I) and the voltage drop across the laser diode (V). In addition, the LIV110 also measures the current from the laser diode’s internal monitor photodiode. The standard LIV110 may be configured with any maximum current up to 250mA. Higher currents are available as custom solutions upon request. The LIV110 is controlled via a set of commands and parameters which are uploaded from the controlling computer. This is followed by the command to begin measurement. The LIV110 then autonomously completes the full measurement sweep and sends the complete data set to the control computer. A graphical software package is provided to ease use of the instrument in a lab environment.
