 Comprehensive laser diode protection features 
 
The Model 5600 Laser Diode Driver is a result of Newport’s continuing 
commitment to provide advanced laser diode instrumentation at affordable 
prices.  
 
Full Featured LDD Offer Complete Test and Characterization 
Capabilities 
 
Advanced circuit designs and careful layout of laser diode drivers provide 
you with an extremely low noise, highly stable output current. External 
analog modulation input allows precision control of the laser output for a 
variety of applications including power level control and wavelength tuning. 
An internal sine or square wave modulator is also available. A monitor 
photodiode is reversed biased at 5 Volts. All laser diode parameters are 
accessible with 16-bit resolution including the laser diode’s forward voltage 
for full characterization. 
 
Comprehensive Safety Features Protect Your Laser Diode  
 
Time tested laser diode protection safety features are incorporated into the 
Laser Diode Driver. Input power module filters provide first stage protection
