Seven Hills International Limited

Seven Hills Raman Analyser


Low Power Laser

Our frequency-stabilized, high power laser (patented) for laboratory, research, and OEM Raman Instrumentation

Our low powered lasers deliver up to 55 mW of single mode laser power. Similar to our high power lasers, the low powered lasers have excellent frequency and intensity stability, and a long lifetime. No ASE filtering or optical isolation required for most applications. The laser is powered with a DC power supply
