Abstract:
A color measurement device comprising a means (12) for electronically recording a digital color image, a target holder (14) extending from the recording means having a distal end (24), and a target (16) at the distal end of the holder, the target having one or more reference color regions thereon.
Abstract:
Color measurement instrument (10) including an integrating sphere (12), a beam splitter (16), a video camera (18), and a spectrograph (20). The beam splitter (16) is aligned with the viewing port (32) of the spectrophotometer to deliver the light reflected from the sample (S) to both the video camera (18) and the spectrograph (20). The video camera (18) provides an image of the position of the sample (S) with respect to the viewing port (32) of the sphere (12), enabling the visual observation and evaluation of the sample position prior to use of the spectrophotometer.
Abstract:
A spectrophotometer, used for measuring a two-dimensional area or a spot area in a rather broad surface of a sample, is provided with a camera (31) for taking a picture of the sample surface. The picture is shown on a display screen (33), and an operator can move a window superimposed on the sample picture on the display screen by using a mouse (34) or the like to a desired place on the sample surface. A sample stage (1) on which the sample (2) is mounted moves according to the movement of the mouse (34), whereby a spectrophotometric measurement of the desired place (two-dimensional area or spot area) on the sample is facilitated.
Abstract:
A scanning densitometer is disclosed for obtaining color density measurements from colored samples, such as color bars and the like. The scanning densitometer includes a densitometer head (100) and a densitometer head transport system (101) having transport bars (102, 103). A sample sheet is positioned under the transport bars (102, 103) and the self-propelled head (100) moves over the sheet along the bars (102, 103) toward an end limit stop (105). During a return movement from the end limit stop (105) to a docking end housing (110), color measurement data is obtained. Upon docking at the docking end housing (110), an optical communications interface is provided so that data from the densitometer head (100) can be transmitted to a host computer.
Abstract:
Abmusterungskammer bestehend aus einem quaderförmigen Gehäuse (1) mit einer Lichtquelle (2), die das Prüfobjekt bestrahlt. Das Prüfobjekt kann durch eine Öffnung betrachtet werden. Bei solchen bekannten Abmusterungskammern können keine reproduzierbaren Vergleiche durchgeführt werden, da Beobachtungsabstand zum Prüfobjekt so wie der Beobachtungswinkel nicht genau festgelegt sind. Die erfindungsgemäße Abmusterungskammer weist einen Vorsatz (3) mit Beobachtungsfenstern (4) sowie einen dreidimensional verstellbaren Prüfobjektträger auf (5), so daß der Beobachtungsabstand (X) festgelegt und der Beobachtungswinkel reproduzierbar einstellbar ist. Farbbeurteilung bei lackierten Teilen.
