Hi-Q Laser RIN Analyzer

The OEwaves’ HI-Q® OE4001 Optical Test Measurement System (TMS) offers a fully automated measurement of ultra-low RIN (Relative Intensity Noise) CW laser sources.

HI-Q® RIN Analyzer is capable of automatically and rapidly measuring relative intensity noise spectrum without complex setup.

This system is unique in wideband measurement. The complete system operates with ease, speed and precision via a simple graphic user interface on a dedicated PC. No additional test equipment required. The unmatched ultra-low relative intensity noise analyzer is scalable to various input wavelength bands and is available with multiple frequency range options. This system is ideal for manufacturing and research environments.
