The PELCO^® Silicon Aperture Frames are 3mm disc-type frames with a thickness of 200µm and square or rectangular apertures. They are useful for a variety of applications:

• Support frame to attach TEM lamellae made with FIB
• Support frame for thin films, foils, wires and fibers
• Mask for thin film research (deposition mask)
