Introduction

Nobuyoshi Toyohara is a prominent inventor based in Sagamihara, Japan. He has made significant contributions to the field of fluorescence observation technology, holding a total of 16 patents. His work has advanced the capabilities of scientific observation and analysis.

Latest Patents

Among his latest patents is an innovative apparatus for fluorescence observation. This apparatus includes an excitation filter that transmits only exciting light of a specific wavelength from the illumination light. Additionally, it features an absorption filter that blocks the exciting light while allowing only the fluorescence generated from a specimen to pass through when the exciting light is directed at it. The design ensures that the interval of a half-value wavelength at the long-wavelength side of the excitation filter and the half-value wavelength at the short-wavelength side of the absorption filter falls within a width of 1 nm to 6 nm. Furthermore, the change in the half-value wavelength of both filters when humidity varies from 10% to 95% is maintained at 0.5 nm or less.
