Optical and laser systems require extremely stable structural platforms.
Even minor vibration or thermal expansion can affect optical alignment and positioning accuracy.
Precision granite structures are widely used in optical and laser industries because of their dimensional stability and vibration damping performance.
Why Optical Systems Require Precision Structures
Optical systems are highly sensitive to:
- Thermal deformation
- Vibration
- Structural instability
- Positioning errors
Precision granite helps maintain stable optical alignment during operation.
Vibration Damping in Laser Equipment
Granite absorbs vibration better than many traditional metal materials.
Improved vibration damping benefits:
- Optical alignment stability
- Laser positioning accuracy
- Surface quality
- Measurement precision
This is especially important in interferometer and optical inspection systems.
Thermal Stability for Optical Alignment
Precision granite provides stable performance under changing temperatures.
Typical granite thermal expansion:
4.6×10⁻⁶/°C
Low thermal deformation helps maintain optical positioning accuracy.
