Abstract: An optical assembly for use with a spectrophotometer. The optical assembly may comprise an illumination source, a detection sensor, a monitor sensor, and an optical piece having a first side adapted to face a sample. The optical piece may define an illumination channel extending from the illumination source toward the first side. The optical piece may also define a detection channel extending from the first side toward the detection sensor. In addition, the optical piece may define a monitor channel extending from the illumination channel toward the monitor sensor. Also, a light emitting diode (LED) assembly for use with an optical measurement device. The LED assembly may comprise a substrate having a top surface and a bottom surface and a plurality of LED dies positioned on the substrate to emit light in a first direction normal to the bottom surface of the substrate. The LED assembly may also comprise a plurality of leads in electrical contact with the plurality of LED dies.

Abstract: An apparatus, system and method for targeting an image formed on an imaging member. The imaging member includes an imaging sensitive layer formed thereon. The imaging member includes imaged and non-imaged areas. Light of a predetermined wavelength reflected from a target area of the imaging member is received. The light reflected from the target area is representative of an image formed on the imaging sensitive layer using energy at approximately the predetermined wavelength. The predetermined wavelength is suitable to initiate crosslinking of the imaging sensitive layer.

Abstract: An auto-tracking spectrophotometer has a moveable look-ahead sensor for scanning at least a portion of a color matrix. The look-ahead sensor finds a portion of the color matrix for measurement by an optical system. The optical system for measuring the color matrix is then guided using the information provided by the look-ahead sensor.

Abstract: A color measurement system includes a hand held color measurement instrument, which may be provided with a wireless interface to a computer. The color measurement system includes a scanning guide for holding the hand held color measurement instrument in proper alignment with a color target. The scanning guide includes a calibration reference to allow convenient calibration of the hand-held color measurement instrument. The hand-held color instrument includes an illumination ring to provide visual feedback to the user. The color of the illumination ring changes in order to display a color similar to that being read by the hand-held color measurement instrument. Color management profiling of the hand held color measurement instrument illumination ring improves the color rendition capability of the illumination ring.
