Porous Ceramic Vacuum Chuck

PhotoMachining is pleased to offer a porous vacuum chuck designed for use with thin films and other flat samples. The chuck has a pore size of less than 25 microns (60 microns optional) assuring uniform suction and strong holding power for even the smallest parts.

The chucks can be manufactured flat and parallel to better than 0.001" over the entire surface. Customer needs to supply only a vacuum pump or in house vacuum with a 1/8" or 1/4" NPT fitting.
