Technology
Bonding/Cutting/Cleaning/Assembly
Technology to support the integrated production system
Bonding/Adhesion
Specification, which can not be satisfied in single prism, can be met by bonding prisms. The adhesion of metal/plastic parts to prisms is also being cured according to customer requirements.
NITTO OPTICAL selects adhesives suitable for the material and product specification. NITTO OPTICAL measures the beam deviation accuracy and spectral characteristics are measured with measuring instruments.
For laser diodes and high-power lasers (YAG lasers, excimer lasers etc.), NITTO OPTICAL has optical contact technology without using adhesives to bond prisms with extreme high flatness.
Cutting
NITTO OPTICAL has various dicers, slicers, and inner blade cutting machines, etc., to satisfy requirements, regardless of quantity, size, prototype and mass production.
Cleaning
The point of the cleaning process is to remove residue such as glass particles, grinding fluid and polishing agents, etc. and organic dirt that stick to optical parts generated in the grinding/ polishing process to improve following thin film coating process.
Product dirts (contamination) are removed by multi-layer ultrasonic cleaning machines in each step of grinding/polishing and thin film coating (vacuum deposition and sputtering).
Assembly
Nitto Optical does not only procduces optical parts but also assembles for the convenience of our customers.
When operations cannot be mechanized for assembly mass production, special toolings are developed and skillfull workers assemble each part accurately and quickly.
