SPG-V500 Laser Spectrum Analyzer
High-Wavelength Resolution and Instantaneous Spectrometric Measurement at Wavelengths from 185 to 1095 nm
The SPG-V500 is an Optical Spectrum Analyzer (OSA) optimized for laser spectrum measurement.
In addition to shortening the time taken for laser wavelength measurements, the instrument can help to visualize mode hopping and other longitudinal mode behavior, resulting in faster development speeds and reduced manufacturing costs for laser light sources and laser modules.
