Abstract: A spectral-characteristic acquisition apparatus and a method of obtaining spectral characteristics. The spectral-characteristic acquisition apparatus includes a conveyor including a first conveyance roller pair disposed in a conveyance direction in which an object is conveyed and a second conveyance roller pair disposed downstream from the first conveyance roller pair in the conveyance direction, a sensor to detect that the object has reached the second conveyance roller pair, circuitry to control the second conveyance roller pair to drive by a predetermined amount with a driving force greater than a driving force of the first conveyance roller pair upon detecting that the object has reached the second conveyance roller pair by the sensor and to stop driving, and a color data obtainer to obtain color data from the object at a position where the object stops moving. In the spectral-characteristic acquisition apparatus, the circuitry estimates a spectral characteristic of the object.

Abstract: A transmission spectroscopy device can direct light into a sample, and determine properties of the sample based on how much light emerges from the sample. The device can use a cell to contain the sample, so that the size of the cell defines the optical path length traversed by light in the sample. To ensure accuracy in the measurements, it is beneficial to calibrate the device by measuring the size of the cell periodically or as needed. To measure the size of the cell, the device can perform a transmission spectroscopy measurement of a known substance, such as pure water, to produce a measured absorbance spectrum of the known substance. The device can subtract a known absorbance spectrum of the known substance from the measured absorbance spectrum to form an oscillatory fringe pattern. The device can determine the size of the cell from a period of the fringe pattern.

Abstract: There are procedures typically used in auto body shops to assist in matching a proposed paint mix with that on undamaged portions of the vehicle. A test panel is taped to a stick and arranged next to the panel to be matched at a couple of angles. The present procedures are unrepeatable and often utilize two individuals. According to embodiments of the present disclosure, a wand has a test panel portion with embedded magnets. The test panel is attracted to the test panel portion via the magnets and the wand holds onto the vehicle panel also via the magnets. The lower side of the test panel portion that sits against the vehicle has at least two flat surfaces at different angles so that the wand can be placed on the surface of the vehicle, or other surface, to assess the paint match from the different angles.

Abstract: Improved colorimetric analysis of liquid samples is provided. A sample holder is used that delivers predetermined volumes of sample individually to each of several colorimetric test patches at the same time with a sliding action. An opaque housing is employed to prevent ambient light from reaching the test patches when color images of the test patches are acquired. Preferably, a mobile electronic device including a camera is attached to the opaque housing to acquire the images. Optical microscopy can be performed in addition to the colorimetric analysis.

Abstract: A measuring cell for a gas analysis spectrometer has an inner chamber for a sample gas to be analyzed and an inlet and an outlet which are connected thereto. A traversing optical path for a measuring beam is formed in the inner chamber. The measuring cell is tubular, the inlet and the outlet are arranged at opposite ends, and the inner chamber of the measuring cell has a cross-sectional shape that is monotonic over the length of the tube and which has an oval-shape at the start, which disappears toward the end. That special shape results in fast gas exchange and thus high dynamics, even with larger measuring cells, which have high sensitivity due to the long optical paths thereof. Two characteristics which until now appeared to be conflicting are thereby combined.
