GV-F-445
The GV-F-445 laser module delivers narrow linewidth, high spectral purity, and excellent wavelength stability, making it ideal for Raman spectroscopy and other precision optical applications. It integrates a laser driver and thermoelectric cooler (TEC) into a single, compact housing to ensure long-term wavelength and power stability.
With its fiber-coupled output, low noise, and high stability (<1%), the GV-F-445 is designed for industrial, medical, and scientific research environments that require consistent optical performance.
