Title: Yoshiaki Hanyu: Innovator in Laser Raman Technology
Introduction
Yoshiaki Hanyu is a prominent inventor based in Yokohama, Japan. He has made significant contributions to the field of laser Raman technology, holding a total of 4 patents. His work has advanced the capabilities of spectroanalysis, making it more precise and efficient.
Latest Patents
One of Hanyu's latest patents is the Laser Raman microprobe. This innovative device separates a laser beam reflected by a sample from the Raman scattered light generated by the sample. It utilizes a filter that transmits or reflects light in a predetermined wavelength region, allowing only the Raman scattered light to be applied to a single-monochromator for spectroanalysis. This design achieves high sensitivity analysis through the single-monochromator.
Another notable patent is the Laser Raman spectrophotometry system and adjustment thereof. This system analyzes a sample material by measuring the spectrum of Raman scattering produced under laser light irradiation. It includes a laser light source for luminescence excitation in addition to the laser light source for Raman scattering. The optical system aligns the optical paths of both laser beams just before they irradiate the specimen. By adjusting the laser power, the luminescence spectrum is calibrated to simulate the luminescence spectrum produced by the Raman scattering excitation. This allows for the cancellation of the luminescence component, enhancing the accuracy of the Raman-scattered light measurement.
