Foreword

GB/T 22057 "from the microscope imaging mechanical reference plane" is divided into two parts. --- Part 1. Tube length 160mm; --- Part 2. Infinity corrected optical system. This section GB/T 22057 "from the microscope imaging mechanical reference plane" in Part 1 of this section to modify the use of ISO 9345-1.1996 "microscopic mechanical reference planes - Part 1 Imaging distance. Tube length 160mm" (in English). This part of ISO 9345-1.1996 main technical differences are as follows. --- Increasing the scope of the standard; --- In Table 1, increasing the nominal value of the objective parfocal distance of 35mm; --- Increasing the nominal value of the objective lens of 35mm parfocal distance marked in Figure 2. For ease of use, this section also made the following editorial changes. --- "This part of ISO 9345" with the words "GB/T 22057 in this section"; --- Delete international standards foreword. This part is proposed by China Machinery Industry Federation. This part of the National Standardization Technical Committee on Photonic and Optical Science (SAC/TC103) centralized.

1 Scope

This section GB/T 22057 specifies the imaging distance of 160mm mechanical tube length of the microscope objective lens and the eyepiece. This section GB/T 22057 suitable for mechanical tube length of 160mm biological, metallurgical and polarized light microscopy. Note. eyepiece and the objective is usually to a specific combination of aberration correction. Therefore, from a certain manufacturer of the objective lens and eyepiece from another manufacturer, although Subject to this section, but it will affect the image quality.

2 Terms and definitions

The following terms and definitions apply to this section. 2.1 The distance between the positioning surface of the objective lens and the object was uncovered plane (see Table 1, Note 2 and Figure 1, Figure 2). 2.2 First image from the positioning surface and the objective lens between the surface (see Figure 1). 2.3 From the initial positioning surface of the eyepiece and the image plane (see Figure 1). 2.4 Distance positioning surfaces converter lens and eyepiece observation positioning surface between (see Figure 1 and Note).
