Latest Patents

One of Sakai's latest inventions is the two-dimensional colorimeter. This device utilizes a beam splitter to focus light onto a rotary filter, allowing a light receiving element to capture light from multiple points on a sample. The rotating filter enables various measurements based on different wavelengths of light. Additionally, a spectral sensor separates the light from specific points into primary wavelength elements, which are then converted into electrical signals. This innovative design allows for accurate chromaticity measurements across multiple points on a sample using a device with a simple construction.

Another significant invention is the optical density detector. This device features a first light source that emits light in a wavelength region that is minimally absorbed by a specific material in a sample. It also includes a second light source that emits light in a wavelength region that is significantly absorbed by the same material. The detector measures the difference in absorbance between the two light sources, which varies depending on the density of the specific material. The device incorporates a temperature measuring unit to ensure accurate readings, compensating for any changes in absorbance due to temperature fluctuations.
