-Part 2: Material quality, finished product standards and packaging methods.

This document is equivalent to ISO 8255-1:2017 "Microscope cover slips Part 1: Dimensional deviation, thickness and optical properties".

Introduction

With the rapid development of various scientific and technological fields at home and abroad, cover glass is widely used in scientific research, teaching, medical care and biotechnology.

Before using optical microscopy to study thin slices of biological specimens cut from organisms, in order to prevent the biological specimens from being to prevent the specimen from dehydrating and deteriorating in the air, it is necessary to bury the specimen with a cover glass, and then place the cover glass in the optical path of the microscope imaging beam.

When designing the aberration correction of the microscope objective, the relevant parameters of the cover glass must be considered so that the optical microscope can play its normal role in various applications.

It can ensure the design, quality and application of optical microscope products, promote coordination among enterprises and improve production efficiency.

In view of the above reasons, the main indicators of cover glass are standardized and normalized according to the parameters and usage functions of the cover glass.

It is very necessary.

GB/T 44276 "Microscope Cover Slips" contains the terms, requirements, markings and logos of cover slips, and Therefore, GB/T 44276 "Microscope Cover Slips" is divided into two parts.

Part 1: Dimensional deviation, thickness and optical properties. The purpose is to specify the dimensional deviation, thickness and optical properties of cover glasses.

Require.

Part 2: Material quality, finished product standards and packaging methods. The purpose is to specify the material quality, finished product standards and packaging methods of cover glasses.

Installation requirements and test methods.
