Foreword

This standard is the result on the basis of GB/T 9247-1996 "microscope condenser" on amending the Supplementary made. This standard and GB/T 9247-1996 The main differences are as follows. --- This release adds the numerical aperture of the condenser manufacturing variations of provisions and a corresponding increase in the numerical aperture of the condenser measurement procedures; --- This version of the 1996 version of the test used "special microscope frame" are replaced by "and the subject of a microscope equipped with a condenser frame"; Condenser stress --- for a polarizing microscope examination instead stress tester checks; --- Cleaning requirements on quality and appearance of the condenser optics are clearly specific quality requirements. Appendix A of this standard is an informative annex. The standard proposed by China Machinery Industry Federation. This standard by the National Standardization Technical Committee photon science and optics (SAC/TC103) centralized. This standard was drafted.

Table 1 Type the numerical aperture Apply objective Magnification range Variable aperture stop Dry Low magnification with condenser ≥0.16 1 ~ 4 - Low magnification with condenser ≥0.4 2 ~ 40 - Abbe two condenser lens ≥0.85 4 ~ 100 have Dark field condenser The inside of the 0.75 to 0.85 The inside of the outer ≥ +0.10 10 ~ 40 - Immersion Abbe three condenser lens ≥1.2 4 ~ 100 have Achromatic/aplanatic condenser ≥1.3 10 ~ 100 have Dark field condenser Medial 1.25 The inside of the outer ≥ +0.15 10 ~ 100-- 3.2 Non-plug-in connection dovetail size of the condenser is removable 37f8.

4 Requirements

When the swing frame front group before 4.1 times put into the condenser lens group, the lens axis of the front group in the focal plane of the condenser lens shift should not exceed 0.02mm. 4.2 condenser aperture stop should be the central axis substantially coincident. 4.3 Variable aperture stop should be basically round, adjusting lightweight and comfortable, the smallest diameter should be less than 2mm. NA 4.4 condenser deviation shall be in accordance with Table 2. ......
