» Butterfly Laser Diode Module
Butterfly laser Diode Module “INFINITY” is a complete system designed to drive butterfly laser diodes. The system has inbuilt TEC controller and butterfly laser diode targeting the applications where it is not needed to change the laser diode unless it is damaged or aged such as RAMAN or other general spectroscopy applications. It easily drives the inbuilt laser diode sinking up to 1.5A with forward voltage up to 3V. The OEM model can be easily integrated to another system.
The system come up in three variants:The OEM
The standalone module
The advanced standalone module
The standalone module comes in attractive cabinet. A potentiometer is provided on the front panel to change the laser power. The key difference between the standalone and its advanced version is the availability of USB interface in the latter. All the necessary control and monitor functions such as laser diode current, TEC current and voltage etc are availed on PC. The OEM module with very small form factor is available without display and cabinet to suit the purpose where space is a constraints. In OEM type the user need to connect external function generator or DAC/potentiometer to change the laser power
