New optoelectronic devices for the Near and Mid-Infrared spectral range open completely new possibilities for portable sensors creation. Using infrared LED-PD optopairs allows developing an instrument that is smaller, less expensive and energy-saving.

mD-1c Minidriver



mD-1c minidriver is designed for power supply of all Lms MIR LED models.


• Minidriver provides qCW mode of operation with fixed signal data parameters (amplitude, repetition rate and pulse duration).
• Possibility of synchronization with an external device (such as LMSNT SDM synchronous detector) with the help of synchronization output contacts.
• Ease of use and durability.
