Latest Patents

One of Saijo's latest inventions is a sample measuring device. The objective of this invention is to simplify the adjustment of the energy beam's position for irradiation and the focal point of a light-collecting mirror part. This device also aims to prevent displacement of the light-collecting part due to vibrations through a straightforward arrangement. The sample measuring device measures light generated from a sample by irradiating it with electron beams. It comprises an electron optical column part that converges the electron beams and a light-collecting mirror part that is strategically positioned to collect the light generated from the sample.

Another notable patent is a spectral ellipsometer designed to eliminate chromatic aberrations. This device features a light incident optical system that focuses polarized light of multiple wavelengths onto a sample surface. The detecting optical system captures the reflected light influenced by the sample surface, allowing for the measurement of changes in elliptical polarization that are characteristic of the sample. A spherical prism polarizer is utilized in the light incident optical system, which has complementary curved surfaces to ensure that all wavelengths are focused at the same position on the sample surface.
