Align Inc states that the tray thickness is 0.3 mm. Having done many Invisalign cases I can confirm that the trays are of a uniform thickness which varies little. You should feel comfortable with Align's quality control in terms of the material they use and the thickness of the trays.

Align Technology manufactures Invisalign aligners that are 0.3mm thick only.

	The retainers are 0.4mm.

	They are virtually unnoticeable and do not interfere with your speech.

all aligners are the same material and the same thickness....I believe the .3 is the correct number

While your dentist said 0.7 mm, they weren't very far off in their guess. All aligners are made in the same place at the same time and will be the same thickness. I believe 0.3 is what they say, but I have never used an instrument to check for sure.
