    • A method for measuring an absorption characteristic of a sample comprises: providing a microstrip waveguide comprising a ground plane, an elongate conductive strip having a first end and a second end, and a dielectric substrate separating the ground plane from the elongate strip such that the strip extends from its first end to its second end in a plane substantially parallel to the ground plane; emitting electromagnetic radiation from a first intermediate position along the microstrip waveguide, said first intermediate position being a position between the first and second ends of the strip, such that said radiation propagates along the waveguide in a direction towards the second end; positioning a sample at a position external to the microstrip waveguide and between the first intermediate position and a second intermediate position along the microstrip waveguide, the second intermediate position being a position between the first intermediate position and the second end, such that at least a portion of the sample is exposed to the evanescent electric field of the propagating radiation; and detecting at least one characteristic of the propagating radiation at said second intermediate position. Corresponding apparatus is also disclosed.

    • There is herein described a method and apparatus for photoimaging. More particularly, there is described a method and apparatus for photoimaging a substrate (e.g. a web) covered with a wet curable photopolymer wherein a rotatable phototool is pressed and rotated against the substrate to create an imaged substrate which is used to form images suitable for forming electrical circuits such as for printed circuit boards (PCBs), flat panel displays and flexible circuits. There is also described a method and apparatus for directly photoimaging a substrate covered with a wet curable photopolymer, wherein the photoimaged substrate is used to form images such as electrical circuits and a method and apparatus for exposing at least part of a solder mask on a printed circuit board (PCB) using a wet curable photopolymer wherein an imaging process may thereafter occur on the area above the solder mask.
