GB/T2985-1999
This standard It is a revision of GB/2985-1991 on the basis of GB/83-1991 Biological Microscopes. In order to meet the needs of international investment and domestic production development, the National Photonics Standardization Technical Committee of the Ministry of Science and Technology issued a meeting to formulate a series of technical standards for the microscope industry. It stipulates the requirements for the installation of the microscope chain and related interfaces: in one aspect, it is necessary to make it fully sold! Some problems arose during the joint work. Therefore, it is very necessary to revise GB/2985-19. The revised biological microscope standard takes into account the connection between the product technical requirements and the basic standard of the microscope. In all or part of the relevant items in the core, the content of the basic standard is directly used, and some contents are adjusted and revised. In addition, the provisions on description and selection are added. Sampling and inspection are listed as a separate chapter as the first general chapter in the standard. The remaining chapters are not numbered. This standard will take effect on This standard was first issued in March 1982 and was officially issued in May 1991.

Focus the scale ruler so that the image of a certain scale line coincides with the vertical line of the cross-hair mirror. Then rotate the mirror to the left and right for several times (at least once) to observe the shift of the scale ruler image. Check all the objective lens positions on the conversion machine in the same way and take the shift value as a fixed value. 5.6 After the objective lens is converted, the center position of the recording surface is rotated (based on 4.6). 5.6.1 Test tools

Then apply force to the object from the side to the right successively: the scale image and the vertical line of the half-scale plate relative to the objective lens are adjusted in sequence. After the force is eliminated, the scale image returns to its original position. At this time, the defocus value of the object should be measured (see 4.8). 5.8.1 Test scale

Then move the mark 5mm along the X direction or Y direction. If the image clarity changes, re-adjust the hand wheel and read the value of the instrument. Calculate the difference between the two readings: During the test, the X direction and Y direction should be calibrated separately. The same direction should be measured at 2~3 positions.
