Macor Ultra-High Vacuum Lens Mount
Alias: Machinable Ceramic Ultra-High Vacuum (UHV) Lens Holder Components
Description：
Ultra-high vacuum lens mount components made of machinable ceramic materials (such as Macor glass-ceramic ceramic) are widely used in applications where vacuum environment, temperature stability, and precision are extremely demanding due to their unique physical and chemical properties (e.g., extremely low air output, high heat resistance, excellent mechanical stability, and good electrical insulation).
Features:
The material of the Macor Ultra-High Vacuum (UHV) Lens Mount (alias: machinable ceramic UHV lens holder component) is a unique engineering material, specifically designed to meet the needs of high-precision and complex industrial extreme applications. Here are the design features and main application areas of these ceramic structural parts:
1. Vacuum compatibility
Outgassing rate is extremely low (cold-state vacuum level: 6.67×10⁻⁴ Pa), and it does not degas after baking, can sustain an ultra-high vacuum environment.
2. Thermal Stability
It can withstand 1000°C in air (aerobic environment) and stabilize to 600°C in vacuum, and its coefficient of thermal expansion matches that of optical glass, which has the ability to maintain mechanical stability and dimensional accuracy, and is not easy to rupture due to reduced thermal stress.
3. Superior electrical insulation
The extremely high electrical insulation strength (30 KV/mm) and volumetric resistance (1016 Ω.cm) make it an ideal material for electronic and high-voltage applications.
4. Chemical stability
It is non-absorbent and has zero air permeability, has good corrosion resistance, and can maintain its performance in a variety of chemical environments.
5. Machinability
Although it is ceramic, it can be precision machined by CNC (accuracy up to 0.001mm) to meet the needs of complex structures. Machinable Macor glass-ceramics can be drilled, milled, ground and polished using conventional metalworking tools without the need for dedicated ceramic processing equipment.
Applications:
Machinable ceramic parts are irreplaceable in the field of cutting-edge technology, and the demand will continue to grow with the advancement of space exploration, chip manufacturing and fusion energy research and development. The following are its core application industries and equipment:
1. Scientific Instrumentation and Analytical Equipment
• Mass Spectrometers and Ion Trap Systems: Used within the vacuum chambers of ion trap mass spectrometers as support structures for ion optics components. The zero porosity and ultra-low outgassing rate (virtually gas-free after baking) of Macor® ceramic maintain an ultra-high vacuum environment (ultimate vacuum level down to 10⁻⁴ Pa), ensuring precision ion transmission.
• Electron Microscopes (SEM/TEM): Support electron lenses or detector assemblies inside the microscope column. Its low thermal expansion coefficient (matching optical materials) and radiation resistance minimize thermal drift impacts on imaging.
2. Semiconductor and Electronics Manufacturing
• Lithography and Wafer Processing Equipment: Fix optical lenses or mirrors in the vacuum chambers of extreme ultraviolet (EUV) lithography machines. Macor’s dimensional stability and high-temperature resistance (≤900°C) safeguard optical path accuracy and prevent particulate contamination.
• Thin-Film Deposition Systems (e.g., PVD/CVD): Serve as heater insulation supports or substrate fixtures, resisting plasma corrosion while maintaining electrical insulation.
3. Aerospace and Defense Technology
• Satellite Optical Systems: Support lens assemblies for space telescopes and remote-sensing cameras. Macor’s lightweight properties, radiation resistance, and thermomechanical stability (adapting to extreme orbital temperature swings) ensure long-term operational stability of optical structures in space.
• Spacecraft Thermal Management Components: Used for thermal insulation window frames or electronic packaging mounts, blocking external heat transfer to onboard equipment.
4. Laser and High-Energy Physics Facilities
• High-Power Lasers: Secure mirrors or lenses in vacuum resonant cavities. Its low thermal deformation prevents laser beam misalignment, enhancing output stability.
• Particle Accelerators and Synchrotron Radiation Sources: Function as beam collimators or vacuum pipeline supports, providing both electrical insulation and radiation resistance.
5. New Energy and Advanced Materials R&D
• Nuclear Fusion Experimental Devices (e.g., Tokamak): Used in the optical diagnostic modules within vacuum vessels, withstanding high-temperature plasma environments and strong magnetic fields.
• Vacuum Heat Treatment Equipment: Used to support temperature-measuring cameras or observation windows in high-temperature sintering furnaces (e.g., vacuum molybdenum strip furnaces), resisting heat without releasing contaminants.
