Optical applications and visual inspection technology
We use optical technology for R&D of new products. We do research and development of advanced sensing technology and laser processing technology to add value to products, and automatic visual inspection technology to guarantee product quality.

Laser processing
We are developing various laser processing technologies, including those for welding, surface modification, and 3D printing, utilizing optical simulation, phenomenon analysis, and thermal fluid analysis.
We are also working on AI-based technology to control the laser process.

Sensing technology
We are developing inspection technology using a light-section method capable of non-contact detection of minute weld defects that uses a microphone array sensor to visualize the sound source. We are also working on quantum cascade laser technology suitable for trace gas analysis, as well as optical measurement technology using quantum cascade lasers.

Inspection and Image processing technology
Applying AI and image processing, we are developing automatic inspection technology enabling visual inspection of products and abnormality detection of equipment with stability comparable to that achieved by human operators. We are also developing technologies to facilitate installation and operation of this inspection technology at manufacturing sites.
