Optics assembly for color measurement system
View Patent ↗An optics assembly for a color measurement system. The optics assembly includes at least one light tube array and a polarization effect minimization element. The optics assembly includes a diffuser, a photocell separator, a precision filter and a second light tube array is provided substantially contained in a housing. The color measurement system includes a multi-purpose filter and the optics assembly. Segmented light is mixed and the polarization qualities of the light are modified so to minimize the effects caused by angular adjustments. A diffuser mixes the segmented light. Additionally, the color measurement system includes an ambient light attachment for collecting light from the viewing area surrounding the computer display. The ambient light collected is then analyzed, and a viewing area profile is created. The viewing area profile then can be used by software to adjust the colors displayed on the computer displays.
1. An optics assembly associated with a color measurement instrument, the optics assembly comprising:
a first light tube array that provides angular constraint to light received by the color measurement instrument, said annular constraint defining a limited range of measurement angles for the color measurement instrument; and
a polarization effect minimization element that modifies polarization qualities of the light received by the color measurement instrument, said modifications reducing the polarization sensitivity of the color measurement instrument.
2. The optics assembly of claim 1 further comprising a diffuser that is adapted to mix the light received by the color measurement instrument before said light received by the color measurement instrument enters the polarization effect minimization element.
3. The optics assembly of claim 1 further comprising a photocell separator.
4. The optics assembly of claim 1 further comprising a precision filter.
5. The optics assembly of claim 1 further comprising a second light tube array.
6. The optics assembly of claim 1 further comprising:
a diffuser,
a photocell separator,
a precision filter,
a second light tube array, and
a housing,
wherein the housing is configured and dimensioned to substantially contain the first and second light tube arrays, the polarization effect minimization element, the diffuser, the photocell separator, and the precision filter.
7. An optics assembly positioned within a color measurement instrument, the optics assembly comprising:
a light tube array including a plurality of light tubes, each light tube configured to receive light from a discrete region of a target area, said light tube array providing angular constraint to light received by the color measurement instrument, said angular constraint defining a limited range of measurement angles for the color measurement instrument; and
a polarization effect minimization element that modifies polarization qualities of the light received by the color measurement instrument, said modifications reducing the polarization sensitivity of the color measurement instrument.
