Abstract:
Arrays of integrated analytical devices and their methods for production are provided. The arrays are useful in the analysis of highly multiplexed optical reactions in large numbers at high densities, including biochemical reactions, such as nucleic acid sequencing reactions. The devices allow the highly sensitive discrimination of optical signals using features such as spectra, amplitude, and time resolution, or combinations thereof. The devices include an integrated diffractive beam shaping element that provides for the spatial separation of light emitted from the optical reactions.
Abstract:
A gas concentration measurement device (100) includes a light source (20) that emits infrared light, a detector (60) that detects the infrared light through a band pass filter (41), and a waveguide member (90) including a wave-guiding portion (93) having a tubular inner peripheral surface, an entrance portion (91) that is formed at one side of the wave-guiding portion (93) and through which the infrared light from the light source (20) is introduced, and an exit portion (92) that is formed at the other side of the wave-guiding portion (93) and guides the infrared light that has passed through the wave-guiding portion (93) toward the detector (60). A portion or entirety of the inner peripheral surface of the wave-guiding portion (93) includes a tapered region having a cross section that decreases along a direction from the entrance portion (91) to the exit portion (92). The waveguide member (90) reflects the infrared light that has entered the wave-guiding portion (93) through the entrance portion (91) in the tapered region, so that energy of the infrared light that is obliquely incident on the band pass filter (41) is reduced.
Abstract:
The present invention discloses a mail detection device and method. The device comprises a broad-band terahertz generator, a collimator, a beam splitter, a fixed reflector, a movable reflector, a wave buncher, a matrix detector, an acquisition card and an information processing module; wherein the information processing module is used for generating a terahertz image of a mail to be detected according to the electric signals sent by the acquisition card when the movable reflector is motionless; and when finding suspicious articles according to the terahertz image of a mail to be detected, the information processing module controls the movable reflector to move, and generates spectral information of the suspicious articles according to an electric signal sequence sent by the acquisition card during the movement of the movable reflector.
Abstract:
A breath analysis system that includes a handle assembly with an analysis cartridge on an upper end thereof. The handle includes a main body portion with a pressure opening and a pressure transducer therein. The analysis cartridge includes a main body portion with an upper portion that defines a breath chamber, a lower portion that defines a fluid chamber and a filter assembly that is movable between a breath capture position and an analysis position. The filter assembly has an opening defined therethrough. In the breath capture position, the opening partially defines the breath chamber and in the analysis position the opening partially defines the fluid chamber. The system also includes an analysis device with a case, a door, a controller that controls the motor and a fluorescence detection assembly and a rotation assembly positioned in the case interior. The rotation assembly includes a shroud with a funnel portion for receiving the analysis cartridge.
Abstract:
A surface plasmon fluorescence analysis device that has a chip holder, a light source, an angle adjustment unit, a light sensor, a filter holder, an excitation light cut filter, a scattered light transmission unit, a transmission adjustment unit, and a control unit. As seen in plan view, the area occupied by the scattered light transmission unit is arranged on the excitation light cut filter or on the filter holder and is smaller than the area of a fluorescence transmission region as seen in plan view.
