摘要： An apparatus and a method are disclosed for performing a light-absorption measurement of a specified amount of sample. A method for performing a light-absorption measurement of a specified amount of sample includes placing the sample on the surface of an apparatus including the surface and a light reflector, the light reflector being mechanically coupled with the surface and separated from the surface by a separation distance, changing the separation distance, while the light reflector remains mechanically coupled with the surface, to a first separation distance, and performing a first light-absorption measurement of the sample via the apparatus, while the separation distance is equal to the first separation distance, and while the sample is subject to pressure force.

摘要： An optical device is provided that includes a converging lens device, a transmitting optical fiber, a sample holder, and a receiving optical fiber. The converging lens device focuses light onto the transmitting optical fiber, which receives the focused light through an entrance face and transmits the light from an exit face, through a sample, and onto the receiving optical fiber. The sample holder holds the sample for analysis. The receiving optical fiber receives the light through an entrance face of the receiving optical fiber after transmission through the sample. The converging lens device is positioned to focus the light onto the entrance face of the transmitting optical fiber such that a half-angle of the angular distribution of the focused light that reaches the entrance face of the transmitting optical fiber is selected to underfill an entrance aperture of the entrance face of the receiving optical fiber in both a spatial dimension and an angular dimension.

摘要： An apparatus is described in which an optical fiber is mounted within a fiber optic holder which includes the non-rotating shaft of a linear actuator. The fiber holder may be held captive in order to restrain the fiber holder and, consequently, the fiber mounted therein, from rotating during operation of the linear actuator, thereby resulting in linear travel with minimal rotational effects and minimal change in optical alignment of the fiber during travel. In addition, an optical path length sensor in conjunction with an optimize dabsorbance method of operation is utilized herein to provide micron precision of the displacement between respective receiving and transmission fibers so as to enable precise absorbance measurements from about 0.005 up to about 2.0 Absorbance Units for any given path length.

摘要： After a liquid sample is dropped onto a sample-holding platform (11), a window plate (22) is moved closer to the sample-holding platform (11) to hold the liquid sample between them. Measurement light is delivered onto the liquid sample, and the light transmitted through the sample is measured. After the measurement is completed, a window plate holder (23) is raised, and a head (14) is moved from a standby position into the gap between the window plate (22) and the sample-holding platform (11). Then, the window plate holder (23) is lowered so as to press the window plate (22) onto the head (14) until the head (14) touches the sample-holding platform (11) below. From this state, the head (14) is swung back to the original position, whereby a wipe material (40) fitted on the head (14) simultaneously wipes off the liquid sample from both the lower surface of the window plate (22) and the upper surface of the sample-holding platform (11). The sleeve-shaped wipe material (40) is held by a rubber block (33) having wiping surfaces and arch springs (35) on both sides of the rubber block (33). Pressing the arch springs (35) enables the wipe material (40) to be easily attached to or detached from the head (14).
