Description: The LDC-3916 16-Channel Laser Diode Controller Laser Diode Controller is designed for simultaneous control of both laser current and temperature in a single mainframe for R&D or production test of optical amplifiers. Its high stability, low-noise current, and temperature controllers also makes it ideal for low-channel count burn-in systems. Laser current source, temperature, and combination controller modules are interchangeable between the 8 and 16 channel mainframes.
The LDC-3916 provides up to 16 channels of laser diode current source and temperature control. It is a space-saving, 3U-high, rack-mountable instrument.
This unit has the following features:
16 independent, isolated channels for multiple laser and TE control
Wide variety of laser controller modules with up to 3A per channel
Dual channel laser current or TE control modules for control of up to 32 laser diodes
Current sources operate in constant current or constant power operating modes with direct modulation up to 1.2MHz
Temperature controllers operate in constant temperature or constant resistance mode with expanded gain setting from 1 to 127
GPIB/IEEE-488 or RS-232 remote control interface
This system has the following modules installed:
Sixteen (16) ILX LDC-3916338
The LDC-3916338 Laser Diode Current Source Module contains one fully independent current source. The current sources provide high stability output up to a maximum drive current of 3.0 Amps, with fully redundant current limits and multiple laser protection features such as contact bounce detection, compliance voltage limit adjust, and 4-wire voltage measurement for precise laser diode forward voltage measurement.
Each module has the following specifications:
Drive Current Output
Output Current Range: 0 to 3000 mA
Setpoint Resolution: 80 microA
Setpoint Accuracy:2 ± 0.1% of full scale
Compliance Voltage: 4.5 V (adjustable voltage limit)
Temperature Coefficient:
