November 9, 2026 | News & Notices SPG-V500 Laser Spectrum Analyzer (Si Type) Upgraded Streamlining 100% Inspection of VCSELs for Faster, Higher-Density AI Data Centers
On November 9, 2026, Shimadzu Corporation upgraded the standard software for the SPG-V500 Laser Spectrum Analyzer (Si type) to “SPG for Laser”, enhancing its functionality.
The SPG-V500 is a polychromator-based (image sensor-based) optical spectrum analyzer. Its high-speed, simultaneous multi-wavelength measurement captures transient spectral behavior, such as mode hopping and mode competition. The product lineup includes two models with different wavelength ranges: the Si type, which covers 185–1095 nm, and the InGaAs type, which covers 950–1700 nm.
With this update, the “High Dynamic Range Measurement Mode”*1, previously available on the InGaAs type, is now also available on the Si type. The Si type can measure a dynamic range of up to 70 dB at high speed using polychromator technology.*2
Fast measurement of SMSR (side-mode suppression ratio), an important evaluation indicator for single-frequency lasers used in optical communications and analytical measurement, helps shorten inspection times and improve throughput.
The growing adoption of generative AI has led to a rapid increase in data traffic. To address challenges such as power consumption and heat generation, the industry is exploring optical interconnect technologies, including CPO (co-packaged optics). VCSELs (vertical-cavity surface-emitting lasers) operating at 850 nm and 1060 nm are attracting attention as light sources for these applications. In addition to its key advantage of high-speed spectral measurement, the SPG-V500 offers high wavelength resolution even when using a multimode fiber input. These capabilities make it well suited to VCSEL inspection and help reduce inspection time, a key challenge in mass production.

“SPG for Laser” is the standard software supplied with the SPG-V500 and is designed specifically for laser measurement. In addition to a spectrum monitor, it features an “Intensity Map” and a “Trend Graph” to visualize changes in spectra over time. The software can be operated intuitively from a PC.
The software also supports automatic creation of measurement conditions and PDF report generation, helping improve the efficiency of laser measurement. Customers currently using the previous “SPG-V500 Measurement Software” can also upgrade to “SPG for Laser” for a fee.
