The invention provides an optical measurement device for measuring light to be inspected. The optical measurement device comprises a light receiving module, a light splitting module, and a plurality of color filters. The light receiving module is used for converting the light to be inspected into a first parallel light. The light splitting module is used for splitting the first parallel light into a plurality of parallel lights to be inspected.

The plurality of parallel lights to be inspected filtered by the plurality of color filters are used to calculate tristimulus values in the CIE color space.

Endoscopic camera head devices and methods are provided using light captured by an endoscope system. Substantially afocal light from the endoscope is manipulated and split. After passing through focusing optics, another beamsplitter is used to split the light again, this time in image space, producing four portions of light that may be further manipulated. The four portions of light are focused onto separate areas of two image sensors. The manipulation of the beams can take several forms, each offering distinct advantages over existing systems when individually displayed, analyzed and/or combined by an image processor.
