D-31M
OPERATION MANUAL
Driver for MID-IR LEDs, QCW and Pulse Mode
1. Application
The driver D-31M is designed as power supply of Mid-IR LEDs.
2. Features
• The driver D-31M provides two modes of operation: Quasi Continuous Wave mode (the mode
of maximum average optical power from the LED) and pulse mode (the mode of maximum
peak optical power from the LED).
• The possibility to tune the LED current amplitude, repetition rate and pulse duration, to select
the optimal mode of the LED.
• The synchronization capability with a lock-in amplifier or with some other device.
• Easy and durable in use.
WARNING!
Do not use multimeter to control the adjust current!
Please, contact your provider regarding these questions.
