A passage (3) for a sample solution is formed in a sapphire base body (2) used as a substrate for semiconductor devices. An LED (4) and a photodiode (5) are formed on the base body (2) by a semiconductor manufacturing process so that they face each other across the passage (3). The LED (4) emits light into the base body (2). This light is transmitted through the sample solution in the passage (3), undergoing absorption according to the concentration and other properties of the solution. The transmitted light passes through the base body (2) and reaches the photodiode (5), producing a detection signal corresponding to the incident light amount. Since the light source and photodetector are integrated with the base body (2) serving as a flow cell, the present device is small and lightweight. Furthermore, no cumbersome task of aligning optical axes in the device-assembling process is needed.

A spectroscopic measurement apparatus includes a light source, an integrator, a first spectroscopic detector, a second spectroscopic detector, and an analysis unit. The integrator includes an internal space in which a measurement object is disposed, a light input portion for inputting light to the internal space, a light output portion for outputting light from the internal space, and a sample attachment portion for attaching the measurement object. The first spectroscopic detector receives the light output from the integrator, disperses the light of a first wavelength region, and acquires first spectrum data. The second spectroscopic detector receives the light output from the integrator, disperses the light of a second wavelength region, and acquires second spectrum data. The first wavelength region and the second wavelength region include a wavelength region partially overlapping each other.

Disclosed is a high reflectivity integrating cavity and device to amplify and detect luminescent emissions produced by small concentrations of materials to be analyzed. Femto or nano molar concentrations of a material can be placed within the high reflectivity integrating cavity. At least the interior surface of the high reflectivity integrating cavity can comprise a coating that, at a designated wavelength of electromagnetic radiation, is transparent and non-absorbing to such designated wavelengths of electromagnetic radiation.
