GB/T 2 2057.1 - 2008 specifies the imagery distance relative to the mechanical reference plane when the microscope barrel is 160mm long. The imagery distance affects the clarity and accuracy of the Microscope imagery. The standard specifies the specific value and tolerance range of the imagery distance when the barrel is 160mm long, and also explains the definition and determination of the mechanical reference plane in detail. Provide precise guidance for Microscope production, assembly and maintenance personnel to ensure that under this barrel length specification, Microscope can achieve stable and high-mass imagery to meet the requirements of scientific research, education and other fields for Microscope imagery performance.
