Hi *! I'm looking for a small vacuum chamber, which can be placed under a microscope. Inside the chamber I want to place a MEMS resonator structure which will be evaluated under low pressure conditions. The dimensions of the chambers should be something like 4"x8" with a height of about 1". I also need electrical contacts inside to let the resonator running. Does anybody have an idea, where I can buy such a vacuum chamber?
