    Abstract: Provided is an optical analyzer which can promote enhancement of measurement sensitivity, cost reduction, size reduction, structural flexibility, disturbance resistance, and the like, at the same time. A laser device to be used in such optical analyzer is also provided. An optical analyzer comprises a laser light source (2); a wavelength selection element (3) for selecting and leading out light having a wavelength substantially equal to the absorption wavelength of an analysis object from among light outputted from the laser light source (2); an optical detection means (5) for detecting the intensity of light red out from the wavelength selection element (3); and a drive current control means (6) for increasing or decreasing the drive current of the laser light source (2) near a specified current value thereof for outputting light of the absorption wavelength, and setting the drive current at such a current value as the intensity of light detected by the optical detection means (5) has a peak value. The laser light source (2), the wavelength selection element (3), and the optical detection means (5) are mounted on a single substrate (11) which can regulate the temperature to a constant level.

    Abstract: Systems and methods for detection of an amphiphile at a liquid crystal interface include the production of circular polarized light. A system 100 for detecting an amphiphile at a liquid crystal interface comprises a source of white collimated light. A circular polarizer is included for circularly polarizing incoming white light. Polarized white light passes through to an LC grid including a suspended LC film and a solution in contact with the LC grid at a surface. A spectrophotometer optically detects the presence of an amphiphile at the surface by determining a change in birefringence exhibited by the suspended LC film. A method for detecting amphiphiles at a liquid crystal water interface comprises shining collimated white light on an LC cell including an LC film, polarizing the white light with a circular polarizer, adding an amphiphile to a solution in contact with the LC film, and optically detecting the presence of the amphiphile by measuring a change in birefringence exhibited by the LC film.
