Abstract: A densitometer apparatus (410) is disclosed and is adapted to provide color density measurements of object samples. The densitometer apparatus (410) comprises a source light (580) for projecting light toward an object sample comprising a control strip (588, 620). A reflection optics assembly (576) is adapted to measure light density reflected from the object sample when the object sample is in the form of a paper control strip. A transmission optics assembly (618) is adapted to measure transmission density of light rays projected through the object sample when the object sample is in the form of a film control strip. A motor assembly (426) operating with a drive wheel assembly (434) and idler wheel assembly (440) automatically moves the object sample (588, 620) through the apparatus (410) adjacent the source light (580). A pair of guides (468, 470) are selectively adjustable by the operator to control movement of the object sample (588, 620) through the apparatus (410). In response to input from a key switch assembly (492) activatable by the operator, the apparatus (410) is adapted to perform various color density measurement and calibration functions, and display appropriate information to the operator through the use of a visual display (490).

Abstract: A portable colorimeter housing has an upper portion which is mounted on a lower portion in a cantilever fashion and is adapted to receive sheets larger than the device for purposes of obtaining tri-stimulus color measurements. An adjustable paper guide determines the distance that a sheet is inserted between upper and lower plates. A sheet to be measured inserted in the opening will operate a micro switch which activates a motor operative to advance the sheet between a motor-driven drive wheel in the lower plate and an idler roller in the upper plate. Transmittance or reflectance measurements are taken by means of photodetector cells including colorimetric filters. A user programmable processor performs pattern recognition and control functions. An optical housing assembly mounted on the upper plate includes a substantially cylindrical body provided with a horizontally extending channel and a mounting bar disposed in the channel is insulated from the cylindrical housing by air space except in peripheral areas of the cylindrical portion, thereby conducting heat generated by the high intensity light source to an area away from heat sensitive filters.

Abstract: A portable colorimeter housing (100) has an upper portion (103) which is mounted on a lower portion (101) in a cantilever fashion and is adapted to receive sheets larger than the device for purposes of obtaining tri-stimulus color measurements. An adjustable paper guide (119) determines the distance that a sheet is inserted between upper (163) and lower (161) plates. A sheet to be measured inserted in the opening (109) will operate a micro switch (139) which activates a motor operative to advance the sheet between a motor driven drive wheel (135) in the lower plate (161) and an idler roller in the upper plate (171). Transmittance or reflectance measurements are taken by means of photodetector cells (242) including colorimetric filters. A user programmable processor performs pattern recognition and control functions.
