High-precision ceramic mirror substrates – the industrial choice for precision and quality.

2026-05-26

Why choose precision ceramic mirror substrates?

1. Extremely low surface roughness

Achieving a Ra of 0.02μm for a super-mirror finish

Ensuring the processing quality of semiconductors, optical components, and precision electronic devices

Reducing the risks of subsequent processing and assembly

2. Ultra-high flatness

Maximum flatness up to 0.001mm

Accuracy is dimension-dependent and can be customized to customer requirements.

Ensuring high consistency between wafers, optical substrates, and electronic components.

3. Stable physical properties

Alumina ceramics: high cost-performance ratio, wear-resistant and corrosion-resistant, suitable for a variety of industrial applications.
