Introduction
With the development of digital information technology, digital imaging display microscopes are playing an increasingly important role in the field of microscopy and are widely used.
It is used in fields such as scientific research, teaching, medical care and manufacturing, and is often equipped with digital imaging displays in various optical, mechanical and electrical integration equipment.
microscopy system. In the modern optical microscope industry, there are a large number of companies that produce digital imaging display microscopes, and the products have different performance and types.
Many categories. Therefore, the various parameters of digital imaging display microscopes produced by different companies should be standardized and unified so that their related components can be consistent.
Mutual replacement is very beneficial to improving the efficiency of optical microscopes, accelerating scientific research and integrating product development.
In view of the above reasons, in order to improve enterprise production efficiency, promote collaborative production among enterprises, and improve scientific research projects and new product development
To increase the speed of research and development, it is necessary to standardize and normalize the various imaging performance information provided to users by digital imaging display microscopes.

3 Terms and definitions
The terms and definitions defined in GB/T 22059 and GB/T 27668 and the following apply to this document.
3.1
An instrument consisting of an objective lens, an image sensor, and a digital display used to display minute details that are invisible to the naked eye.
Note. The system can include image enhancement, image analysis and archiving, etc.
3.2
image sensorimagesensor
A device that converts optical imaging into digital images.
3.3
digital display digitaldisplay
An output device for the visual display of digital images and other information.
3.4
resolvingpowerlimit
The maximum spatial frequency that can be distinguished in object space, expressed in lp/mm.
Note. Due to factors such as reduced contrast and moiré pattern, the actual obtained resolution power will always be lower than the ultimate resolution power. Also, it depends on the sensor
