Abstract: An imaging assembly for the viewing, imaging, and analysis of chemiluminescent or bioluminescent samples in gels or other substrates, in which an adjustable camera and lens module having a prime or fixed lens or a focusing lens is moved to change the field of view by shifting the focal plane of the camera and lens module. The imaging assembly can also include a mirror to bend or fold the optical path between the camera and lens module and the target area having a sample, in which the mirror can move in the same vertical direction as the camera and lens module. Further, the camera and lens module can be configured to more move in a diagonal direction relative to the location of the imaging target area. The imaging assembly can further have a duct system adaptable to adjust with the movement of the camera and lens module.

Abstract: Systems and methods of interaction with invisible printing. In one embodiment, a printed page includes a printable surface, an invisible machine readable code disposed on the printable surface; and a human viewable image disposed on the printable surface. The invisible machine readable code may not absorb or reflect visible light substantially differently from the printable surface, in one embodiment. The invisible machine readable code may be detectable when exposed to infrared and/or ultraviolet light.
