SEMIXICON DIASEMI EXTRA LARGE MPCVD DIAMOND WINDOW
Diamond windows—typically made from CVD (chemical vapor deposition) diamond—are used in environments where extreme thermal, mechanical, and optical performance are required. Their unique combination of ultra-high thermal conductivity, wide optical transparency, chemical inertness, and hardness makes them irreplaceable in several advanced fields.
1. High-Power Laser Systems
Diamond windows are widely used in laser optics, especially in CO₂ and high-energy laser systems.
Transparent across IR wavelengths
Exceptional thermal conductivity (~2000 W/m·K) prevents thermal lensing
High damage threshold
Typical use: laser output windows, protective optics in industrial cutting/welding systems.
2. Microwave & RF Systems
Diamond is highly transparent to microwaves and has low dielectric loss.
Used in gyrotrons, klystrons, and plasma heating systems
Critical in fusion research (e.g., tokamaks)
Applications:
Windows for high-power microwave transmission
Vacuum barriers in plasma systems
3. Synchrotron & X-ray Applications
Diamond windows are ideal for X-ray beamlines due to:
Low X-ray absorption
High mechanical strength under pressure
Radiation resistance
Used in:
Synchrotron radiation facilities
X-ray diffraction and imaging systems
4. Harsh Chemical & High-Pressure Environments
Diamond is chemically inert and mechanically robust.
Resistant to acids, alkalis, and corrosive gases
Withstands extreme pressure differentials
Applications:
Viewports in chemical reactors
High-pressure chambers
Deep-sea or oil/gas instrumentation
5. Infrared (IR) Optical Windows
Diamond offers broadband transmission (UV to far-IR).
Ideal for IR sensing and imaging systems
Used in harsh or high-temperature environments
Applications:
Thermal imaging systems
Missile domes and aerospace sensors
6. Semiconductor & Plasma Processing Equipment
In semiconductor fabrication (etching, deposition):
Diamond windows isolate plasma while allowing energy transmission
Long lifetime compared to quartz or sapphire
Applications:
Plasma CVD chambers
RF coupling windows
7. Defense & Aerospace
Diamond windows are used where durability and performance are critical:
Hypersonic vehicle sensors
High-speed IR domes
Radiation-hardened optical systems
8. Scientific & Metrology Instruments
High-pressure optical cells (e.g., diamond anvil cells)
Spectroscopy windows (Raman, IR, THz)
