Abstract: Aspects of the disclosure relate to a multi-pass gas cell that includes a set of two or more reflectors, an input collimating optical component, and an output focusing optical component. The input and output optical components are integrated with at least one of the two or more reflectors. For example, the input and output optical components may be integrated on opposite ends of a single one of the reflectors or may be integrated on the same end of a single reflector. The input and output optical components may further be integrated with different reflectors. In some examples, the set of reflectors and optical components may be fabricated within the same substrate.

Abstract: The present disclosure includes a spectrometric measuring device for a measurement point of the process automation system, including a broadband light source for radiating light through an entrance aperture onto a sample to be measured, wherein the beam bundles of the light form an irradiation plane, a light limiter that limits the light at an angle to the irradiation plane, whereby a different amount of light results at this angle. The device further includes a dispersive element for separating the light according to its wavelength and a detector for receiving light separated according to its wavelength, wherein the light source beams the light through the sample to the entrance aperture, the light limiter and the dispersive element, and the light strikes the detector.

Abstract: A concentration correction system includes an infrared detector and components that produce an aggregate emission of infrared radiation. A mirror assembly includes a mirror and is changeable between a correcting configuration and a measuring configuration. In the correcting configuration, the mirror produces a mirror signal incident on the detector. The mirror assembly also obstructs external body infrared radiation from reaching the detector. In the measuring configuration, the mirror assembly allows the external body infrared radiation onto the detector. A concentration correction method includes receiving external body infrared radiation and simultaneously receiving a first portion of the aggregate emission. A measurement value indicative of concentration is recorded from the detector. A second portion of the aggregate emission reflected with the mirror and produces a mirror signal incident on the detector. A correction value corresponding to the mirror signal is recorded from the detector and used to correct the measurement value.

Abstract: A spectral imaging device (12) includes an image sensor (28), an illumination source (14), a refractive, optical element (24A), a mover assembly (24C) (29), and a control system (30). The image sensor (28) acquires data to construct a two-dimensional spectral image (13A) during a data acquisition time (346). The illumination source (14) generates an illumination beam (16) that illuminates the sample (10) to create a modified beam (16I) that follow a beam path (16B) from the sample (10) to the image sensor (28). The refractive, optical element (24A) is spaced apart a separation distance (42) from the sample (10) along the beam path (16B). During the data acquisition time (346), the control system (30) controls the illumination source (14) to generate the illumination beam (16), controls the mover assembly (29) (24C) to modulate the separation distance (42), and controls the image sensor (28) to capture the data.

Abstract: A multi-angle colorimeter employs a multi-angle mode and a symmetrical arrangement mode in an optical arrangement. Light detection on both sides of the symmetrical arrangement is performed by a single photodetector unit. The photodetector unit is used on both sides, and thus, the device becomes simpler, without any impact on individual difference in characteristics of multiple photodetector units. Conversely, elements for illumination can be used on both sides. Also in a case where multiple photodetector units are used, the size and cost of the device can be reduced with the use of a photodetector unit having a relatively low wavelength resolution as a photodetector unit to be used on one side. This enables to reduce an attitude error due to relative tilting of a measurement surface while reducing the size and cost of the device.

Abstract: A spectrophotometer 10 includes built-in detector 24 and external detector 32. When a mountable/removable optical path switcher 23a is installed in a specimen chamber 23, measurement based on detection signals from built-in detector 24 is replaced by measurement based on detection signals from external detector 32. The spectrophotometer further includes a measurement data threshold-value storage unit 51 that stores threshold value T for measurement data from built-in detector 24 or external detector 32, and a light-receiving detector recognition unit 52 that recognizes which detector is able to receive the measuring light beam based on the results of a comparison between threshold value T and measurement data from built-in detector 24 or external detector 32 while the measuring light beam is being introduced into specimen chamber 23.

Abstract: The present invention has been accomplished to provide an atomic absorption spectrophotometer capable of obtaining measurement data always in the state where the lowest detection limit performance is optimized, without depending on the frequency of the power supply. In a control program which runs on the microcomputer chip 42 mounted on the atomic absorption spectrophotometer 110, a plurality of lighting periods of the light sources 11 and 12 and extraction periods of the sampling data are memorized, whose lowest detection limit performance are optimized for the frequencies (50 Hz and 60 Hz) of the AC power source for driving the AC motor 22. In using the apparatus, by the control program, the frequency of the power source used in this apparatus is identified, the lighting period and sampling data extraction period corresponding to the identified frequency and the measurement mode that a user of the apparatus has previously set are selected from among a plurality of memorized values, and the appropriate lighting period is set to the hardware (PLD 43). Accordingly, without depending on the frequency, it is possible to obtain measurement data always in the state where the lowest detection limit performance is optimized.

Abstract: A radiation pulse, such as from a solar simulator, is spectrally analyzed over a selected sampling pulse that is shorter in duration than the radiation pulse and is timed to begin after the start of the radiation pulse. A deformable membrane mirror is controlled to function as a high speed shutter in the path of the radiation pulse. When not deformed, the mirror reflects the radiation pulse into an optical instrument, such as a spectroradiometer. A sampling pulse is generated for a selected time after the start of the radiation pulse and is applied to the mirror to ensure total reflection of the radiation pulse only for the duration of the sampling pulse. Controls are provided to adjust the start time and duration of the sampling pulse, and to adjust the sensitivity of sensing the start of the radiation pulse.
