    Abstract: A gas measurement apparatus includes an optical resonator that resonates light, a light source that generates light for irradiation of the optical resonator, and a photodetector that detects light taken out of the optical resonator. The optical resonator includes a plurality of mirrors, a holding member, a hollow tubular member, a hollow tubular member, and a temperature adjustment instrument. The holding member is lower in thermal expansion coefficient than the hollow tubular member. The hollow tubular member includes a portion higher in thermal conductivity than the holding member and a bellows higher in elasticity than a first portion. The hollow tubular member is equal to or higher than the hollow tubular member in thermal conductivity, and is provided as far as positions of the plurality of mirrors on an inner side of the bellows.

    Abstract: A seamless fumed silica monolithic integrating cavity device tailored to analyzing a flowed sample. The device is configured to facilitate optical measurements taken from a sample flowed through a cavity of the device. The cavity is defined by a fumed silica monolith with the added feature of a fused quartz lining on the surface of the monolith. This provides an intermediate surface that allows for cleaning and reuse of the highly effective diffuse light scattering fumed silica monolith. The lining may be placed under pressure or vacuum to structurally enhance mechanical integrity of the underlying monolith. Thus, continued or reliably repeated use of the device may be appreciated as well as use in more industrial environments that are prone to vibration. Additionally, while well suited for flow-based sample analysis, a valve of the cavity may be utilized for holding a sample in a temporarily static state for measurement.

    Abstract: An apparatus and method of use are provided; the apparatus having at least a degasser, a hollow core fiber HCF, an optical mechanism, a detector, and circuitry. The degasser enables gasses to permeate out of a liquid into the degasser interior. The propagator establishes a low-pressure area that helps to pull the gas from the degasser interior into the HCF interior, where the optical mechanism delivers electromagnetic radiation EMR that interacts with the gas. The detector determines EMR absorption, producing output signals which are sent to the circuitry. Circuitry controls the optical mechanism and analyzes the output signals to quantify the concentration of gas in the HCF and in the liquid.

    Abstract: A microplate reader simultaneously obtains Raman measurements from samples contained in non-adjacent wells. At least two Raman probes are positioned perpendicularly above or below the microplate to simultaneously acquire Raman spectra data of the non-adjacent liquid samples. Each probe is coupled to a laser and a spectrometer and includes a lens focusing laser light within the sample and collecting light from the sample for the spectrometer. The spectrometer may include a 2D imaging sensor (sCMOS or CCD) to image light from multiple probes simultaneously, spaced from one another to reduce crosstalk. A positioner moves the microplate plate or probes to acquire data from a different subset of non-adjacent samples, and may also vary laser focus within wells during data acquisition. Multiple fluorescence probes may simultaneously acquire fluorescence data from the same samples, or non-adjacent samples. Probes may be fiber-coupled and positioned within a reaction chamber of a liquid handling system.

    Abstract: A substrate 1 includes a color center excited by excitation light, and at least a pair of reflection members 21a, 21b are arranged with gaps from the substrate 1. The substrate 1 causes the excitation light entering the substrate 1 to exit through its surfaces without reflection, and the reflection members 21a, 21b cause the exited excitation light to reflect at the reflection surface 21-1 or 21-2 and enter the substrate 1, and cause the excitation light to repeatedly enter and exit the substrate 1 and thereby pass through the substrate 1 only a predetermined number of times. Here, the irradiating device 4 emits the excitation light such that the excitation light is incident to the reflection surface 21-1 or 21-2 with an angle perpendicular to one axis among two axes of the reflection surface 21-1 or 21-2 and with a predetermined slant angle from the other axis.
