摘要： The method of analyzing absorbance of one or more liquid samples (3) arranged in the wells (2) of a microplate (1) comprises the steps of setting a desired wavelength falling within the wavelength range of 380 nm-750 nm for absorbance measurement (101), illuminating the samples (3) using electromagnetic radiation having a bandwidth of at most 20 nm around the set wavelength (102), measuring radiant flux transmitted through each sample (3) (103), on the basis of measured radiant flux values, determining an absorbance value for each sample (3) (104), and visualizing the absorbance values on a display (12) as a matrix comprising a plurality of cells (23), each cell (23) corresponding to a well (2) of the microplate (1) (105). The set wavelength is used as an input for determining the visual properties of the cells (23).

摘要： Modulation-encoded light, using different spectral bin coded light components, can illuminate a stationary or moving (relative) target object or scene. Response signal processing can use information about the respective different time-varying modulation functions, to decode to recover information about a respective response parameter affected by the target object or scene. Electrical or optical modulation encoding can be used. LED-based spectroscopic analysis of a composition of a target (e.g., SpO2, glucose, etc.) can be performed; such can optionally include decoding of encoded optical modulation functions. Baffles or apertures or optics can be used, such as to constrain light provided by particular LEDs. Coded light illumination can be used with a focal plane array light imager receiving response light for inspecting a moving semiconductor or other target. Encoding can use orthogonal functions, such as an RGB illumination sequence, or a sequence of combinations of spectrally contiguous or non-contiguous colors.

摘要： An image forming apparatus includes an optical sensor configured to detect an image formed on an intermediate transfer belt. The optical sensor includes a first light emitting diode (LED), a second LED, a first photodiode (PD), and a second PD on a substrate. The first PD is arranged at a position at which specularly reflected light of light emitted from the first LED can be received, and scattered reflected light of light emitted from the second LED can be received. The second PD is arranged at a position at which scattered reflected light of light emitted from the second LED can be received. A light receiving surface of the first PD and a light receiving surface of the second PD are formed at different angles. The light receiving surface of the first PD has an area that is smaller than an area of the light receiving surface of the second PD.

摘要： A device and a method of using the device for improving sensitivity, speed, and easy-to-use of a colorimetric assay of a liquid sample are provided. The device includes a first plate and a second plate, spacers, and a textured surface. The two plates each have a sample contact surface and are movable relative to each other into an open configuration or a closed configuration. The sample is deposited on one or both plates in the open configuration. Thereafter, the closed configuration is formed where the plates compress at least part of the deposited sample into a continuous layer. The textured surface is disposed on the sample contact surface of the second plate and has a textured structure that scatters light, from which an optical signal such as a colorimetric or fluorescent signal can be obtained for analyzing the sample.

摘要： Disclosed is an instrument analyzing elemental composition of a sample, including a measurement assembly including: an exciter generating an excitation directed at a target position to cause emission from the sample; a detector assembly receiving the emission from the sample at the target position, arranged to generate one or more measurement signals that are descriptive of the emission; an imaging apparatus for capturing images of an area around the target position; and a controller for carrying out a measurement, arranged to operate the exciter to generate the excitation and to carry out analysis of the elemental composition of the sample based on the measurement signals. The controller performs reliability analysis associated with the measurement by operating the imaging apparatus to capture images of the sample, determining estimated reliability of the measurement based on the captured images, and selectively issuing an indication of measurement reliability based on the estimated reliability.
