Abstract: A microscope is modified to allow for precise imaging of samples using different filters at different focal planes under computer control. A filter accessory includes a filter disc having bandpass filters. The filter disc may be rotated to move a selected filter into the optical path between a light source and the microscope sample. Adjustment of the image plane of the microscope is controlled by the computer using feedback from a lens position sensor.

Abstract: The present invention relates to an improved dual beam multichannel spectrophotomer employing a simple and novel optical system in combination with photodiode arrays and a unique logrithmic data converter to convert light signals to absorbance. In particular, the optical system utilizes optical elements in a novel arrangement to direct a pair of equivalent sample and reference beams in an essentially parallel formation respectively through a sample and reference cell and to focus and direct the emergent sample and reference beams to a single flat horizontally ruled grating which disperses each of the sample and reference beams respectively onto a pair of vertically disposed photodiode arrays whereby the light signals are converted into absorbance units (AU) by an unique logarithmic data converter. The spectrophotometer is highly accurate, has very low drift, less than 2.times.10.sup.-4 AU/.degree.C., and very low noise, less than .+-.2.times.10.sup.-5 AU. The dual beam multichannel spectrophotomer is particularly suitable for use in high pressure liquid chromatography to record the absorbance spectrum of the samples as they are being eluted from the chromatographic column.

Abstract: An accessory is provided to convert a conventional microscope to a microspectrofluorimeter. The accessory includes a filter disc having bandpass filters separated by opaque segments. The filter disc is rapidly and continuously rotated to move the filter sequentially into the optical path between a wideband light source and a microscope sample. Photon counting of radiation from the sample is synchronized to the position of the filters during rotation by means of synchronization marks on the filter disc. The same accessory may be positioned between the sample and a detector to detect emitted light of different frequencies.

Abstract: Automatic zeroing apparatus zeroes an infrared gas analyzer automatically upon the occurrence of preselected conditions to indicate zero in the absence of absorption of infrared radiation by a gas mixture being analyzed. The gas analyzer has a sample cell for containing a gas mixture to be analyzed. Infrared radiation directed through the sample cell is detected at a preselected wavelength to produce a detection signal. A signal processor outputs a signal systematically related to the difference between the detection signal and a reference signal. For zeroing the sample cell is filled with gas substantially nonabsorbent of infrared radiation at the respective characteristic wavelength. A comparator produces an error signal when the output signal differs from zero. A gain control automatically controls the signal level of the detection signal to reduce the output signal substantially to zero with the nonabsorbent gas filling the sample cell. The preselected conditions may include the passage of a predetermined time and a temperature drift beyond a predetermined limit.
