Summary
The Very Large Telescope Survey Telescope (VST) features an active optics system to correct aberrations. Its primary mirror support system, designed for stability and earthquake protection, has passed qualification testing.
Area of Science:
- Astronomy and Astrophysics
- Optical Engineering
Background:
- The Very Large Telescope Survey Telescope (VST) requires precise optical performance for astronomical surveys.
- Active optics systems are crucial for correcting optical aberrations in large telescopes.
Purpose of the Study:
- To describe the primary mirror support system of the VST.
- To present the results of the qualification test campaign for the mirror support system.
Main Methods:
- Detailed description of the axial and lateral support mechanisms for the 2.6 m primary mirror.
- Inclusion of safety devices for earthquake protection.
- Presentation of qualification test results.
Main Results:
- The active optics system effectively corrects low-order aberrations.
- The primary mirror support system provides stable axial and lateral support.
- Qualification tests confirm the system's performance and safety features.
Conclusions:
- The VST's mirror support system is well-designed and meets performance requirements.
- The system's active optics and safety features are validated through testing.
- The VST is ready for advanced astronomical surveys.
