Latest Patents

One of Tokuhisa Ito's latest patents is a comparison type dimension measuring method and apparatus using a laser. This system utilizes a laser that provides linearly polarized light, which is directed by a polarization beam splitter into a microscope system where a specimen is mounted. The reflected polarized light is rotated by a quarter wave plate and passes through the beam splitter to a multi-element line sensor. The laser light is scanned over the specimen, and threshold intensities are determined on indicia of known separation on a reference specimen to calibrate the distance measured by the line sensor. Another notable patent is an automatic focusing device in a microscope system. This device allows for vertical focusing of a specimen by placing an enlarging condenser lens between a light source and a half mirror in an automatic focus detecting system. This setup presents an enlarged image of the light source to the objective of the focusing microscope.
