Classification: CPC G | IPC G

Claim 15:
16. An X-ray, gamma ray, charged particle and/or thermal neutron collimator device comprising:
At least two substrates or host wafers positioned on the top of each other,
Wherein at least one said substrate is made by additive manufacturing,
Wherein said substrate made by additive manufacturing is having an array of substantially uniform parallel hollow pores there through, the pores having characteristic lateral dimensions in the plane of the host wafers
Wherein the pores in said substrate made by additive manufacturing are within the range of from about 0.1 mm to about 20 mm,
Wherein at least one said substrate is a semiconductor substrate,
Wherein said semiconductor substrate is having an array of substantially uniform parallel hollow pores there through, the pores having characteristic lateral dimensions in the plane of the host wafer;
Wherein the pores in said semiconductor substrate are within the range of from about 0.1 μm to about 20 μm,
Wherein said substrates having first and second surfaces substantially perpendicular to the axis of the pores,
Wherein said pores are of regular shapes and are spatially ordered across said surfaces of the wafer thus forming ordered pore arrays.
