■ Area of Expertise

Based on practical experience in optical design, I deal with optical theory, primarily focusing on geometrical optics and wave optics.

 

■ Site Objectives

This site aims to provide a thorough explanation of the fundamental theories of geometrical optics and wave optics, which form the basis of optical design. While supplementing assumptions and derivation processes often omitted in specialized textbooks, we have created a space where you can steadily learn theories useful in the practical application of optical design and measurement. We hope this will be helpful in deepening the understanding of students studying optics and those involved in research and development.

 

■Educational Background

I majored in electronic engineering at university and graduate school, and worked on research into semiconductor materials. In the process, I was also exposed to a variety of experiments involving light, such as weak light detection, polarization measurement, and time-resolved measurement.

 

■ Work Experience

After completing my master's program, I joined a major optical equipment manufacturer, where I first encountered optical design. For more than twenty years since then, I have been responsible for the optical systems used in the development of microscopes, spectroscopic instruments, and other optical devices employed across research, industrial, and medical fields. The design software I have used includes CODE‑V and OpTaliX, and I currently work primarily with ZEMAX.

 

■ Expertise Reflected in This Site  

The expertise presented on this site is grounded in a careful, mathematically oriented approach to optical theory. I place particular emphasis on clear and thorough derivations, avoiding omitted assumptions so that readers can follow the full logical flow of each explanation. Drawing on both geometrical and wave optics, I aim to systematically organize fundamental theories that are useful in practical optical design and measurement.

 

■ Qualifications and Interests

• Silver Level Certification, International Optical Technology Certification Association (2015)

• Pre‑1st Grade, Practical Mathematics Proficiency Test (2008)

I enjoy mathematical approaches, so my explanations often use mathematical formulas. I hope to convey even a little of the fascinating aspects of optics and mathematics.

 

■ Operating Policy

This site deals with the fundamental theories of optics themselves, rather than practical design know-how. We operate this site with great care to ensure that the knowledge and know-how gained within the company are not leaked to external parties.

 

■ Finally
This website is run by an individual and therefore has a limited scope, but we plan to gradually expand its content and continue to organize and systematize fundamental theories useful for practical applications in optics. I also hope that, in the future, I may have the opportunity to shape these foundational theories into a coherent book. Your visits back whenever you feel like it would be greatly appreciated.
