Color measurement instrument with asymmetric tapered sample area optical enclosure

摘要

A color measurement instrument such as a reflection densitometer or a spectral reflectometer is fitted with an asymmetric tapered sample area optical enclosure to allow an improved operator sight line to the sample target area and allow ease of placement on the sample target, while allowing for the standard 45° illumination/90° measurement geometry. The disclosed structure is particularly suitable for use as a hand-held instrument.
