Dear Philip,

It is very important to have the heater on all the time. You wont get nice images without heating up the Volta phase plate.

Best,
Maryam

How important is the heater? Would it work without it?

Hi Garry,

Unfortunately I don't know of any alternative source for phase plate hardware. The phase plates themselves can be homemade - it's just a grid with ~10 nm amorphous carbon. But the aperture/phase plate holder is special with a built-in heater.

Cheers,

Rado

Hello,
i?m trying to get a quote for a Volta phase plate for a G2 Tecnai F30.  FEI has told me they don?t supply these.  can anyone tell me if there are other companies that do?
thanks,
Garry

Hi Philip,

The heater is very important. Without it there will be beam-induced contamination and charging which will make the phase plate unusable.

Cheers,

Rado
