Published in the “Bulletin of Invention L1 1 for 19o4.

The invention relates to polarization colorimeters based on a comparison of colors; and the luminance of the photometric Iol of the object under study with an Iol of comparison with any other color and luminance, with the livery of TWO and transparent cuvees.

The proposed solar cell. The cryolite has the more complex KOHCTDVJ; 1111, gives precise редlereleii and differs from the ones in that it has a bottom, an polarizer g, the radiating rays with mutually per1) pH cells, 1 planes and 14 MIMI and HPHIMMIMIMIMI, and HPHIMMIMIMIMI, and HPHMIMIMIMIMI and HPHMIMIMI; quartz; lomsensor of the right and left quartz with a laneseioia on, the IWM I1kaloy OITIChGG density or Iok, and;., IOfloi (: eee.

From the output reflective prism (4), the light beam enters the cuvette (5) along the left hand wheel and into the cuvette (5), which is of different sizes in length: 200 mm, 100 mm, 50 mm, 10 mm. Depending on the intensity of the coloration, this or

After the tetuaprism (7), the light enters the quartz compensator, consisting of three three 1; linier1: wedge (8) from left quartz, wedge (9) from optical glass and clip (10) n.i right quartz. The quartz compensator intercepts the plane of polarization of the linearly polarized light beams of the right and left knees of the instrument (the optical axis of the quartz cells of the optical input p output plane).

After the quartz compensator, the light enters the analyzer (11) (after the frazka Rieter prism prismatic prism; oddiarna;).

Then the light enters the glass optical filter (12), consisting of five glasses of different color (with a spectrophotometric characteristic), which are inserted into the sockets of the revolver head and introduced into the OnrnHecKyio scheme depending on; From here, the light enters the Galilean optical tube, which consists of a pz lens with two linens; 1 (13) and (14) and a negative eye (15).

The device can be introduced with colored glass for comparison. For this purpose, gdredmusmotrepa revolving. head, in which the necessary quantity of glasses (Ifi) is placed in comparison.

It is also possible to use in the right knee a colorimeter, a cuvette with a standard liquid, such as this. comparisons (instead of sranpen glass).

The elimination of chromatism in the field of view (color non-color) of one half of the field of vision when working without reference standards is obtained and the irime of a quartz compensator, from the right) of the right quartz, the rotational dispersion of which is equal and reverse for the package. and also, falsiches of light filters (12).

Liiiia igkala is associated with the movable quartz wedge (8). which moves with the clip (scale is not shown in the drawing). With the help of the ocular of the: scale of the scale to count in a. Absolute values of the claim-omyr dapnge (of the original,

PLASTICS, etc.).

11-dimensional 1 polarized gauge parameter is produced as follows. First of all, the position of the movable quartz wedge (8) is determined, with к-fluoro in the absence of measurable; the capacity of the brightly stf-both of their semi-fields is equalized (the device’s instrument-point). In this situation, the zero of the nonius of the scale is brought under the bullets of the scale (in the drawing, the reference diagrams and the scale are not normal).

After the zero point is placed in the left knee of the device, the zioveta is installed with the measured liquid. as a result, one-half of the intensity of one half of the eyesight skill.

The equalization of the guest with the first one in the MOUTH case is carried out by moving the nodVIl quartz wedge (8) and associated with it. On a scale, the readout of the desired quantity (optical {с и лот), etc.

The subject is invented and
