Foreword

GB/T 19864 "stereo microscope" is divided into two parts. --- Part 1. universal stereo microscope; --- Part 2. High performance stereo microscope. This section GB/T Part of 219,864. This section drafted in accordance with GB/T 1.1-2009 given rules. This Part replaces GB/T 19864.2-2005 "stereomicroscopes - Part 2. High performance stereo microscope," and this section GB/T 19864.2-2005 main changes are as follows. --- Chapter 1 increases the scope of application; --- Remove φ23.2 F8 h8 Eyepiece and eyepiece Connecting dimensions; --- Original standard 4.1.4 The title read. like object plane deviation in the center of the left and right center of the field; --- Original standard 4.1.5 The title should read. about the optical system of the light beam direction deviations and its requirements increase to about convergence of 10 ', is divergent about 45'; --- Resolution lens center of the field increased to not less than 2500NA line pairs/mm; --- Electrical safety performance of the pressure test requirements and methods for increasing the DC test. This part of ISO 11884-2.2007 "minimum requirements for optics and photonics stereomicroscopes - Part 2. High performance reflects Microscopy Mirror "the degree of consistency is not equivalent. This part of ISO 11884-2.2007 The main differences are as follows. --- Increasing the basic parameters of the instrument; --- Press accustomed to "optical and mechanical properties" table format to the requirements of the provisions of narration; --- In the "optical and mechanical properties" section adds about clear imaging, the basic requirements of the transmission mechanism, lighting, cleaning, etc.; --- Increase the requirements for the appearance of the instrument; --- Environmental testing provides only under conditions of transport packaging for environmental adaptability requirements.
