ARC possesses the machining techniques, skill and equipment to fabricate a wide variety of apertures in a similarly wide variety of materials. The aspect ratio of aperture opening to material thickness is generally limited to a 1:20 ratio. Shown on the right in Figure 1 is an aperture with a wide series of holes ranging from 15um to 960um.
Aperture construction varies from a free-standing sheet aperture where the aperture holes range from tens of nanometers to millimeters and material thicknesses range from sub-micron foil to tens of millimeters.Figure 2 (right) illustrates a 30nm thin foil with a 5nm diameter hole. ARC used its ultra machining techniques and then verified the dimensions using our in-house Scanning Electron Microscope (SEM)
