《GB/T 22057.2-2008显微镜 相对机械参考平面的成像距离 第2部分:无限远校正光学系统》由TC103(全国光学和光子学标准化技术委员会)归口,主管部门为中国机械工业联合会。
GB/T22057《显微镜 相对机械参考平面的成像距离》分为两个部分,本部分为GB/T22057《显微镜 相对机械参考平面的成像距离》的第2部分。本部分为首次发布。 GB/T22057的本部分规定了物镜、目镜的像距和具有无限远校正光学系统显微镜“标准”镜筒透镜的焦距。GB/T22057的本部分适用于机械筒长为无限远的生物、金相和偏光显微镜。
本部分与ISO 9345-2:2003的主要技术差异为:
――增加了标准的适用范围;
――删除了标准的附录A和附录B。
为便于使用,本部分还做了下列编辑性修改:
――“ISO 9345的本部分”改为“GB/T 22057的本部分”;
――删除国际标准的前言。
Scope
This Part of GB/T 22057 specifies the image distances of objectives, eyepieces and focal lengths of "standard" tube lenses for microscopes with infinity-corrected optical systems. This part of GB/T 22057 is applicable to biological, metallographic and polarizing microscopes whose mechanical tube length is infinite. NOTE: Aberrations are usually corrected for one specific combination of eyepiece, objective, and tube lenses. Therefore, the combination of an objective lens from one manufacturer and a tube lens or eyepiece from another manufacturer, while complying with this standard, may introduce errors in magnification and/or optical performance.
