Abrégé

This spectrometer is used in measurement of the thickness of a surface layer in a sample of interest having a multilayer structure in which the surface layer and a lower layer are layered. The spectrometer comprises: a light-receiving unit that receives, from the sample of interest, reflection of light emitted from the surface layer side of the sample of interest; and a spectroscopic unit that generates a reflection spectrum by spectrally diffracting the reflection. The spectroscopic unit generates the reflection spectrum in a spectral wavelength range in which the round-trip internal transmittance of the surface layer becomes equal to or more than a prescribed lower limit value, and the round-trip internal transmittance of a combined layer of the surface layer and the lower layer becomes equal to or less than a prescribed upper limit value.

An electrophoretic mobility measurement cell having: a container having a rectangular parallelepiped inner space (11) for introducing a sample solution; two electrodes (14) for applying an electric field to the inner space (11), the two electrodes being formed inside the container in integral fashion with the container; a tubular sample injection part (17) in communication with the inner space (11); a tubular sample extraction part (18) in communication with the inner space (11); a first cap (21) for covering the sample injection part (17) and sealing the inner space (11); and a second cap (22) for covering the sample extraction part (18) and sealing the inner space (11). The first cap (21) has a first side surface (21b) that makes contact with the inner surface (17a) of the tubular sample injection part (17) when the cap is mounted. The inner surface (17a) is formed so that the cross-sectional area of the tube increases in accordance with the distance from the inner space (11). The first side surface (21b) has a cross-sectional surface area that gradually narrows along the insertion direction of the first cap (21). The cell and electrode part are integrally formed, the electrode part is disposable together with the cell, and foam is unlikely to remain during injection of the sample solution.

Abrégé

A quantum efficiency measurement method includes the steps of: disposing a sample at a predetermined position in an integrator having an integrating space; applying excitation light to the sample and measuring a spectrum in the integrating space as a first spectrum through a second window; configuring an excitation light incident portion so that excitation light after having passed through the sample is not reflected in the integrating space; applying the excitation light to the sample and measuring a spectrum in the integrating space as a second spectrum through the second window; and calculating a quantum efficiency of the sample based on a component constituting a part of the first spectrum and corresponding to a wavelength range of the excitation light, and a component constituting a part of the second spectrum and corresponding to a wavelength range of light generated by the sample from the received excitation light.

Abrégé

An optical measurement apparatus includes a hemispherical portion having a diffuse reflection layer on an inner wall, and a plane portion disposed to involve a substantial center of curvature of the hemispherical portion and close an opening of the hemispherical portion, and having a reflection layer on an inner surface side of the hemispherical portion. The plane portion includes: at least one of a window for introducing light to be homogenized in an integrating space formed between the hemispherical portion and the plane portion, and a window for extracting light homogenized in the integrating space; an outer portion formed of a first material chiefly causing specular reflection, and occupying at least a region of a predetermined width from an outermost circumference; and an inner portion formed of a second material chiefly causing diffuse reflection and having a higher reflectance for at least an ultraviolet region than the first material.

Abrégé

A sample (OBJ1) which is an object the quantum efficiency of which is to be measured and a reference body (REF1) having a known reflectance characteristic are separately attached to a sample window (2) provided to a flat mirror (5). The spectra of the sample (OBJ1) and the reference body (REF1) separately attached to the sample window (2) are obtained through measurement by a spectrometer. The quantum efficiency of the sample (OBJ1) is determined referring to the spectra. The opening surface of the observation window (3) is substantially flush with the exposed surface of the sample (OBJ1) and the reference body (REF1). Therefore, it is prevented that fluorescence emitted from the sample (OBJ1) irradiated by exciting light (L1) and exciting light (L1) reflected from the sample (OBJ1) directly pass through the observation window (3).

Abrégé

The polarization angle θ1 of a polarizer (14) is set, and the reflection intensity S1 in a cross Nicol state and the reference reflection intensity Ref1 of a liquid crystal cell (15) are measured. A different polarization angle θ2 is then set, and the reflection intensity S2 in a cross Nicol state and the reference reflection intensity Ref2 of the liquid crystal cell are measured. The rations S1/Ref1, S2/Ref2 of measured intensities and the ratio S1·Ref2/S2·Ref1 is determined in order to cancel the background components of the reference reflection intensities Ref1, Ref2 thus determining the value of cell gap accurately.
