Littman Sacher lasertechnik Singapore

Sacher Lasertechnik uses their own unique patented technology, Littman/Metcalf lasers are capable of measuring & performing analyses (with output of 630nm .. 2450nm, up to 100mW). 

It is has high flexibility with systems of wavelength regime of 635nm to 2450nm. It is totally independent and fully self-sufficient with the plug-and-play applications (automated piezo tuning with power read-out)  It is able to maintain a constant current and constant power operation & excellent long term locking stability.  The powerful littman laser has excellent frequency locking performance with high resonance free piezo modulation, high frequency laser current modulation.

The laser is available in motorised & manual tuning system; with the motorised version controlled remotely via GPIB, RS232 and USB
