    Abstract: A dual beam spectrometer for conducting both turbidimetric and colormetric measurements includes a housing with a light source. The housing further includes source exit apertures that form light from the light source into a sample light beam and reference light beam. A sample cartridge for containing sample material to be measured is mounted in the housing in the path of the sample light beam. The spectrometer also includes a detector assembly for detecting the sample light beam and the reference light beam. The detector assembly includes a first detector that senses or detects sample light beam and a second detector that senses or detects the reference light beam. A sample light beam detection aperture tube is positioned in the housing between the sample cartridge and the first detector. Similarly, a reference light beam detection aperture tube is positioned between the sample cartridge and the second detector.

    Abstract: A technology is provided which enables imaging to be more conveniently performed under parallel light illumination without requiring an imaging apparatus to have a function of generating parallel light. Imaging is performed with a regulation plate 2 having a multitude of fine through holes penetrating in a vertical direction placed between an illuminator 12 for emitting diffused light L1 and a well plate WP for carrying biological specimens serving as an imaging object in wells W. Inner wall surfaces of the through holes are blackened to suppress light reflectance to be low and an image with good contrast is obtained by irradiating only light incident at a small incident angle on the regulation plate 2 to the wells W.

    Abstract: A system for wide-range spectral measurement includes one or more broadband sources, an adjustable Fabry-Perot etalon, and a detector. The one or more broadband sources is to illuminate a sample, wherein the one or more broadband sources have a short broadband source coherence length. The adjustable Fabry-Perot etalon is to optically process the reflected light to extract spectral information with fine spectral resolution. The detector is to detect reflected light from the sample, wherein the reflected light is comprised of multiple narrow-band subsets of the illumination light having long coherence lengths and is optically processed using a plurality of settings for the adjustable Fabry-Perot etalon, and wherein the plurality of settings includes a separation of the Fabry-Perot etalon plates that is greater than the broadband source coherence length but that is less than the long coherence lengths.

    Abstract: A fluorescence viewing device 1A is configured to take a difference between one of an image of a first frame and an image of a second frame output from an imaging device 12 and the other of the first frame image and the second frame image stored in an image storage means, whereby clear observed images can be obtained without influence of background light. In the fluorescence viewing device 1A, an exposure time of a fluorescence image acquisition period and an exposure time of a background image acquisition period are different from each other. When the exposure time of the fluorescence image acquisition period and the exposure time of the background image acquisition period are made asymmetric in this manner, the observed images are acquired with good smoothness. Since ON/OFF durations of excitation light also become asymmetric according to the asymmetry of the exposure times, the device can reduce user's feeling of strangeness due to blinking of the excitation light.
