    Abstract: An in-situ technique is provided for automatically verifying proper operation of a photometric device, such as a cell density probe (CDP). The CDP has a first detector and a second detector. The first detector senses light that is transmitted from a light source of the CDP. The second detector senses light that has passed through an optical gap at a tip of the CDP, wherein the sensed light has been reduced in intensity due to light absorption. Electrical current provided to the light source is reduced, and the resultant values of a light characteristic (such as intensity) at the first and second detectors are sensed. These values from the detectors are compared against one or more predicted values. If the CDP is operating properly, the values from the detectors will be consistent with the predicted values. If there is a malfunction in the CDP, then the values from the detectors will be inconsistent with the predicted values.

    Abstract: The disclosure is directed to a test media reader module including a housing, a membrane, and an optical imager. The housing is configured to receive a test media adapter and has a barrier wall configured to separate the test media adapter from an interior of the housing. The barrier wall includes a window having an interior side and an exterior side. The membrane is transparent to a wavelength useful for imaging test media in the test media adapter. The membrane has a reactive region and overlies at least a portion of the exterior side of the window. The optical imager is located interior to the housing and is configured to image the test media located on the exterior side of the window along an optical path extending through the window and the membrane.

    Abstract: The present invention relates generally to the field of biochemical laboratory. More particularly the invention relates to the improved and more accurate instrumental features of equipment used as e.g. fluorometers, photometers and luminometers. The object of the invention is achieved by providing an optical measurement instrument for photoluminescence and chemiluminescence measurements wherein there is chemiluminescence detector in such a proximity to the sample that the emission radiation from the sample may reach the detector via a direct path. This way it is possible to achieve an essentially improved accuracy of the chemiluminescence measurement as well as an improved overall efficiency of the optical measurements.

    Abstract: The invention relates to an imaging system for optical automatic analysers, especially fluorescence readers. On the sample side, the imaging system contains a cylindrical lens array and a prism array, which is arranged upstream of the cylindrical lens array. The prismatic effect of the prisms of the prism array lies in the direction of the cylinder axes of the cylindrical lenses. Together with a telescopic imaging system, the inventive imaging system creates a number of parallel cylindrical focussing volumes between the cylindrical lens array and a detector array, these focussing volumes being slanted towards the optical axis of the telescopic system in relation to the vertical. The arrangement enables the detection of fluorescence with a large aperture in one direction, and at the same time enables depth selective analysis of the fluorescence signal, especially the discrimination of the fluorescent radiation originating from the solution above.

    Abstract: A microscopic unit for a multi-station modular FTIR spectrometer system is disclosed. The microscope unit, which has a Cassegrain objective, not only provides the usual optical path for radiation during visual observation, and for infrared radiation in the transmission mode, but also provides a separate optical path for infrared radiation in the reflectance mode and in a macroscopic transmission mode. An optical switching wheel is in the path of entering radiation, which may enter through any of three ports; and the wheel is movable into a plurality of alternative positions, including a position in which radiation entering through one port passes through the wheel toward the objective, a position in which radiation entering through the same port is reflected by a wheel-carried mirror along the separate optical path, a position in which a wheel-carried mirror causes radiation to bypass the microscope, and positions in which other wheel-carried mirrors reflect into the microscope radiation entering through other ports.
