Hello Lai,

The inside of the DLP9500 is not a vacuum nor is it filled with inert gas. It is filled with proprietary material that ensures reliable operation of the micro-mirrors.

Is there a reason you are asking?

Hello again Lai,

Since the seal is truly hermetic, this device has been used for vacuum applications. For space applications, temperature is the important factor.

Hi Fizix Expert：

Can it be used in a vacuum environment of 10⁻³Pa?

Hello again Lai,

That should not present an issue, but keep the DMD above 10 degrees C.
