X-ray Anti-Scatter Grids and Nuclear Collimators

Creatv has developed proprietary methods to fabricate high-aspect-ratio metal and tungsten composite grids and collimators. Creatv’s grids improve the clarity, resolution and contrast of x-ray images.

Millimeter Waveguides

Solid copper waveguides with copper substrates are fabricated with straight walls, precision flatness and height.

X-ray Masks

Precision gold x-ray masks are fabricated in various geometries and thicknesses. This example has slits 29 µm wide and 3000 µm long in 210 µm thick gold, with 98 µm period. Overall mask size is 6 x 6 cm2.
