Phase Change Disc Initializer
System to crystalize the recording layer of phase change discs (CD-RW, DVD-RW, etc.) initialization achieved using a high power laser. It is used in the final stage of the production process. (Number of patents registered: 2)
Next-Generation Optical Disk Test System
System to test the next-generation of optical discs such as Blu-ray and HD DVD very precisely. It is used in the process of disc production. (Number of patents registered: 1)
Noncontact 3D Scanner
This technology was developed through "Knowledge Amalgamation Project" sponsored by Shizuoka Pref. by applying the triangulation method of laser light and a CCD device. These dimensional measurements are made without physical contact, and it is widely used for measurements of vehicle bodies and other car parts. (Industrial-academic joint research program) (Number of patents registered: 21) (Number of patents applied: 2)
Collinear Holographic Media Evaluation System
Evaluation system for 1-terabyte discs of more advanced generation than current next generation discs. It is used for the development of holographic recording. (Number of patents registered: 14)
Nano-fabrication System
An application of optical disc technology, this 'Direct write' system fabricates a wide area in 50-nm steps with laser diode at high speed. It is used in various industries. (Number of patents registered: 12)
Portable X-ray Residual Stress Analyzer
The system measures residual stress of the metallic material surface. Measurement speed is 90 sec/point that is very fast. The system is small, lightweight, portable, and can also be operated with a battery. It is useful for on-site measurements.
(Number of patents registered: 36) (Number of patents applied: 6)
Reference Laser Beam
(Light Source)
Reference light source using laser diode. It is used for coherent or reference light source for other optical equipment.
Optical Equipment – Wavefront Sensor
Real-time measurements of the wavefronts transmitted through objective lens used inside the optical pickup head. It also adjusts the optimum point in the production process.
