Abstract: Multi-beam e-beam columns and inspection systems that use such multi-beam e-beam columns are disclosed. A multi-beam e-beam column configured in accordance with the present disclosure may include an electron source and a multi-lens array configured to produce a plurality of beamlets utilizing electrons provided by the electron source. The multi-lens array may be further configured to shift a focus of at least one particular beamlet of the plurality of beamlets such that the focus of the at least one particular beamlet is different from a focus of at least one other beamlet of the plurality of beamlets.

Abstract: Attractiveness of consumer products is enhanced by use of scintillating fluorescent light collecting fibers contained in those products. The fibers collect ambient light of various wavelengths, some not visible, along their length which is collected within the fiber and emitted as visible light at the ends of the fibers. The emitted light can be used to enhance the consumer appeal of the product or promote its use. Specific consumer products disclosed include toothbrushes and liquid soap dispensers.

Abstract: A compact magnetic energy filter having at least four magnetic fields to deflect the trajectory of an electron beam from the entrance window to the exit slit. A rotational symmetry axis is located midway between the second and third magnetic fields. The magnetic fields on the opposite sides of the rotational symmetry axis are opposite in polarity.

Abstract: A kit, primarily for use in marketing customer supplies, e.g. checks, check books, and check book covers, which is the form of a three panel per side portfolio, including a pocket for order forms, clear plastic coating on one face of the portfolio blank which folds and is second to provide six panel faces of protected graphics, and a single layer in the integral hinge regions for compact folding.
