Compound X-ray lens having multiple aligned zone plates

A method for fabricating a compound zone plate comprising:

• placing a first zone plate frame comprising a first zone plate over a second zone plate frame comprising a second zone plate;
• placing microbeads and an adhesive mechanically between the first zone plate frame and the second zone plate frame;
• and
• aligning the first zone plate to the second zone plate prior to hardening of the adhesive by transmitting x-rays through the first zone plate and the second zone plate and detecting the x-rays and positioning the first zone plate relative to the second zone plate in response to the detected x-rays.

A method for fabricating a compound zone plate comprising:

• placing microbeads and an adhesive mechanically between the first zone plate frame and the second zone plate frame;
• aligning the first zone plate to the second zone plate prior to hardening of the adhesive;
• and
• aligning a third zone plate to the first zone plate and the second zone plate.

A method for fabricating a compound zone plate comprising:

• placing a first zone plate frame comprising a first zone plate over a second zone plate frame comprising a second zone plate;
• placing microbeads and an adhesive mechanically between the first zone plate frame and the second zone plate frame;
• aligning the first zone plate to the second zone plate prior to hardening of the adhesive;
• and
• wherein different sized microbeads are used in the adhesive between a base frame and the first zone plate frame relative to the adhesive between the base frame and the second zone plate frame to control a relative spacing of the zone plate frames with respect to each other.

A method for fabricating a compound zone plate comprising:

• bonding a first zone plate frame including a first zone plate over a base frame;
• placing a second zone plate frame including a second zone plate over the base frame;
• inserting a spacer between the base frame and the second zone plate frame, wherein the spacer includes microbeads;
• and
• aligning the first zone plate to the second zone plate by using the microbeads to facilitate inplane relative movement between the first zone plate and the second zone plate.

A method for fabricating a compound zone plate comprising:

• bonding a first zone plate frame comprising a first zone plate over a base frame;
• bonding a second zone plate frame comprising a second zone plate over the base frame;
• positioning and holding the base frame with respect to the first and second zone plate frames with an x, y axis positioner;
• and
• aligning the first zone plate to the second zone plate by using the microbeads to facilitate inplane relative movement between the first zone plate and the second zone plate.
