Features
- Instantaneous Spectrometric Measurements, Simultaneous Multi-Wavelength Measurements, and Real-Time Measurements
The SPG-V500 is a polychromator-type optical spectrum analyzer using an array sensor.
Using an array sensor, this laser spectrometer instantly obtains an optical spectrum. It visualizes laser mode hopping and laser characteristics due to thermal and current variations, and speeds up measurement times. It helps with the assembly and adjustment of laser light sources by suppressing mode hopping and reducing noise.
- Achieves High Wavelength Resolution Despite Using Multimode Fibers (MMF)
This Optical Spectrum Analyzer achieves a high wavelength resolution of approximately 0.02 nm (Typ.) despite using multimode fibers*1. It allows for easy optical input simply by orienting the optical fibers toward the measurement target*2, enabling easy evaluation of fine longitudinal mode movements.
- Wide Measurement Range Covering Ultraviolet (UV), Visible (VIS), and Near-Infrared (NIR) Light
Wavelengths from 185 to 1095 nm can be accommodated with a single spectrometer unit, enabling laser wavelength measurements of everything from the 266 nm fundamental wave of deep ultraviolet lasers to wavelengths after wavelength conversion*3.
- *1: The recommended core diameter is 200 to 600 µm. Spatial incidence is also possible.
- *2: Even higher wavelength resolution measurements can be obtained by utilizing higher order light.
- *3: When measuring the fundamental wave, use an order separation filter to remove higher harmonics.
