Title: Apparatus for non-contact measurement of refractive index
Inventor: ICHIKAWA MASAMITSU
IPC: G01N21/41
Filed: 1986-01-27
Abstract: PURPOSE:To enhance manufacturing efficiency by enabling the measurement of a refractive index in a real time during preparation work, by applying the scale corresponding to the refractive index of a liquid to be measured to the laser beam arrival side surface of a beaker having the liquid to be measured injected therein. CONSTITUTION:When the laser beam 2 emitted from an emitter is allowed to irradiate the constant position A on the side surface of a cubic beaker 1 made of a transparent member having uniform refractive index over the entire surface thereof at a constant angle, the emitted beam 2 arrives a point B when a liquid 3 to be measured is not injected in the beaker 1. When the liquid 3 is injected in the beaker 1, beam 2 arrives the point C of the side surface 1b of the beaker 1 in the case of pure water and the beam arrival point changes to points D-I with the change in a refractive index and, therefore, a scale 4 corresponding to a refractive index is preliminarily provided to the side surface 1b. When a battery liquid is prepared, water is injected in the beaker 1 and the emitted beam 2 is set to the point C and sulfuric acid is dripped under stirring to successively move the emitted beam 2 from the point C to D E F and, when the refractive index reached a required value, the dripping of sulfuric acid is stopped. As mentioned above, the refractive index can be measured in a real time and manufacturing efficiency can be enhanced.
