Abstract

PURPOSE:To exclude the scanning spot and shortage of concentration, by carrying out the raster scanning and reducing by optical lens to project on the sample and operating varying quantity of light transmitted the sample by the microcomputer. CONSTITUTION:The sample 9 is placed by positioning on the aperture grill 7 and the photosensor 10 is closely stuck to the sample 9. The CRT cathode-ray tube 3 is operated by switching on the power source switch 15 and raster scanning starts on the cathode-ray tube and the same time, it is reduced to desired value by transmitting the optical lens 5 and then, is projected on the sample 9 through the grill 7. Varying quantity of light by the dimension or depth of the network point 22 passed through the sample 9 is read by the sensor and is substituted for the variation of voltage. Then, said variation having the concentration of preliminary set optional network point only is inputted in the microcomputer and is operaed in that place to operate the concentration of corresponding face.
