1. Capture Spectral Behavior with High-resolution in a blink of an eye

Spectrum measurement can be as short as 6 μs, and instantaneous wavelength behavior such as mode hopping can be captured. Spectrum measurement of short-pulse lasers is also possible. The wavelength resolution is approximately 0.02 nm (Typ.) , which enables accurate and finer spectrum measurement.


2. One-stop Solution for Wide Wavelength Range

SPG-V500 can measure a wide wavelength range from DUV at 185 nm to NIR at 1095 nm. Especially, DUV laser(e.g. Excimer laser, Wavelength conversion laser) can be measured.

*SPG-V500 for InGaAs Type (950nm - 1700nm) will also be released soon.

3. Reduces Time and Effort for Optical Axis Adjustment

SPG-V500 realizes easy light input with multimode fiber, reduces the time for optical axis adjustment and simplifies laser measurements. Also, measurement can be performed by simply orientating the optical fiber to the scattered light from the power meter, allowing simultaneous measurement of wavelength and output intensity.

4. User-Friendly Software Specialized for Laser Measurement

SPG-V500 has a simple design with only a power button. The user simply selects the measurement conditions on the software for SPG-V500. The user's operation is summarized in 3 steps: "Input laser" → "Select measurement conditions" → "Start measurement“, therefore the equipment is easy for anyone to use. The spectrum graph changing in real time can be tracked on the Software. The software also includes intensity map and trend graph, the fluctuation of the laser intensity, the change of the peak number, and the transition of the center wavelength of the fitting curve, which promotes understanding characteristics of lasers visually.

User’s Voice

LP用_下線.png



Users of SPG-V500 have praised its real-time and high-resolution measurement and its high workability for laser light input into the equipment.


  • Thanks to the easy light input with multimode fiber, the sensitivity is overwhelmingly higher than that of conventional spectrum analyzer. It is also amazing that a high wavelength resolution of 0.02 nm(Typ.) could be obtained so easily.
  • I feel SPG-V500 has great value because it eliminates the effort for fine optical adjustments that used to be required for wavelength measurement. The equipment makes development and inspection more efficient.
  • I was surprised that the optical adjustment process of "moving, stopping, and checking," which I had taken for granted in laser measurement, could be performed smoothly without stopping.
  • Conventionally, optical adjustment using a single-mode fiber was time-consuming in order to obtain wavelength resolution that could separate longitudinal modes. With the SPG-V500, the optical adjustment is eliminated, which greatly reduces the evaluation time.
  • In addition to real-time measurement of the wavelength which I expected, intensity and peak number data required for optical adjustment of the laser are visualized on the PC screen, so I think it is very easy to use the equipment. I think it can be used effectively for speeding up development and inspection processes of our lasers.
  • Conventional optical spectrum analyzers tend to require a lot of button operations when setting conditions. But with the SPG-V500, we were surprised to be able to obtain spectrum information without detailed settings.

Comment by Tera-Photonics Research Team at the RIKEN, Japan

~Visualization of Terahertz-Wave Signals~
“Previously, signals had to be checked while delicately adjusting the position at each frequency, which required massive amounts of time for measurements, but the SPG-V500 completely eliminated the need for such steps, making detection easy. Furthermore, using a multi-mode fiber normally reduces resolution, but the SPG-V500 was able to couple many signals while maintaining high resolution. “

LP用_分光分野の特長.png

Diffraction gratings are widely used as dispersive elements in instruments that use optical principles. They are used in optical analysis instruments such as spectrophotometers, in biochemical analyzers in the medical field, and in food-quality control. Shimadzu diffraction gratings are manufactured by precisely replicating master gratings produced using a holographic exposure process that creates extremely low stray light gratings. In addition, blaze processing using ion-beam etching provides diffraction efficiency comparable to that of mechanically ruled gratings. By combining low stray light and high efficiency while minimizing variation in optical performance, these gratings enhance the performance of instruments that require highly accurate measurements.

Process monitoring in semiconductor manufacturing is essential for ensuring process quality and improving efficiency. In etching and deposition processes, where real-time monitoring is required, diffraction gratings are used in systems that analyze changes in light to track progress of the processes. Shimadzu diffraction gratings offer a broad lineup featuring low stray light, high efficiency, and stable quality, enabling selection of the optimal grating for each application. Customization of specifications is also available.

Fabrication Process

Shimadzu gratings are made by replicating a “Master”. We were the first to develop the technology for manufacturing blazed holographic gratings (BHG), which, compared to conventional mechanically ruled gratings, ensure less stray light without any reduction in diffraction efficiency. This unique grating manufacturing technology was previously patented in Japan as Japanese Patent No. 1046763 and was awarded the Okochi Memorial Prize.

Achievements

The Planetary Spectroscopic Observation Satellite "Hisaki" (SPRINT‒A), equipped with a diffraction grating manufactured by Shimadzu, is a space telescope dedicated to planetary observation that remotely observes Venus, Mars, Jupiter, etc. from the orbit of the satellite orbiting the Earth. By observing extreme ultraviolet light in outer space, which cannot be detected on Earth, we analyze the atmosphere of planets and contribute to the elucidation of their mysteries.
