Fuji Ideck's vacuum windows are made by their one and only technology which never be subject to heat effect. The windewos were developed by collaboration with Japan Atomic Energy Agency (JAEA) for the purpose of the ITER (International Thermonuclear Experimental Reactor) use.
Ultrahigh Vacuum Window - TF series
Features
No Head Effect
You can get clear transmission without any deflections and any scatterings. This is achieved by the special sealing technology which never uses heat in the assembly process.
Perfect Uniform Coating
We mount windows on flanges at room temperature after coating windows. This method realizes a perfect uniform coating.
Pressure Resisting Structure
Windows never come off even at counter pressure.
No Magnetic and No Radiative
You can use our windows in magnetic and radiation environment because we don't use any kovar materials which are high magnetic and high radiative.
No Zn Soldering
We promise that your vacuum chamber will be kept clean because we never use Zn which can vaporize in high pressure environment.
Wide Slection of Window Material
CaF2, MgF2, ZnSe, Ge, Si, LiF, quart, crystalline quartz, sapphire, BK7, lead glass, KRS-5, etc.
★Wedge, concave-convex lens options are available.

- He leakage < 1 x 10-10Pa m3/sec (We already achieved 0.1 x 10-10Pa m3/sec)
- Bakable < 200 degC (depends on window materials and flange dimentions)
Extreme High Vacuum Window - VX series
Features
Big Effective Diameter φ440 mm
We can offer greater than φ440 mm. Besides, you can use our windows at counter pressure.
Super-high Surface Acuuracy
About 90% of effective area, surface accuracy is pretty high. λ/20 (λ= 633 nm) is feasible. Please contact us for further details.
Re-polishable / Replaceable Window Materials
you can save money by re-polishing and replacing windows only.
No Head Effect
You can get clear trans
mission without any deflections and any scatterings. This is achieved by the special sealing technology which never uses heat for assembly process.

We promise that your vacuum chamber will be kept clean because we never use Zn which can vaporize in high pressure environment.
Good Impact Resistance
Passed XYZ/15G/3000 cycles (tested by JAEA)
Bakable Despite Big Diameter
VX series can correct the difference of thermal expantion. This feature allows you to bake big diameter of VX. But sometimes you need some forced cooling structure.
