PURPOSE:To measure dynamical properties and optical those of a low-viscosity fluid simultaneously by providing a device, which irradiates electromagnetic waves to the fluid between a detecting element and a sample saucer, and a detector which detects electromagnetic waves from said fluid. CONSTITUTION:A sample saucer 5 and a quartz glass disc 6 for detection are shut in a closed space by a sample tank 4. A laser light 18 is polarized linearly by a polarizer 16 and passes a quartz glass window 15, an aperture plate 14, and the quartz glass disc 6 and is irradiated to a sample fluid 13. Measurement in a prescribed atmospherical temperature or a vacuum or pressured atmospheric is possible with respect to the sample fluid 13 between the quartz glass disc 3 and the quartz glass disc 2 for detection on the sample saucer 5. By this constitution, dynamical properties and optical those of the low-viscosity fluid are measured simultaneously. |
