Foreword
This standard is the result of the "microscope eyepieces" basis GB/T 9246-1996 on the revised supplement made.
This standard and GB/T 9246-1996 The main differences are as follows.
--- Canceled photography eyepiece, eyepiece projection in the range;
--- Press the number of categories in the field of view, an increase of ultra-wide field eyepiece; pressing the aberration correction increases the state is divided into ordinary eyepiece flat field eyepiece; increase
Added classified according to the exit pupil distance is divided into ordinary and high eye point eyepiece eyepiece;
--- Eyepiece eyepiece with separate pairs, highlighting the requirement for a pair of eyepiece binocular microscope; the two eyepiece optical axis
And coaxial with the outer diameter of the requirement of "point of view" expressed and defined as 8 '; and increase the eyepiece diopter with the diopter indication "zero
Bit "requirement; increased the flat-field eyepiece performance requirements; high eye point eyepiece determine the effective exit pupil distance should not be less than 18mm;
--- The test tool "eyepiece comprehensive performance tester" with "focal length, microscope frame, micrometer, 10 ×/40 × objective lens, the front telescope
Mirror frame and the diopter and connecting pipe "and other conventional instrument.
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. Nanjing East to facilitate photoelectric Industrial Co., Ltd., Shanghai Polytechnic University, Shanghai Institute of optical instruments, Nanjing Jiangnan Yong
New Optical Co.
The main drafters of this standard. Yang Guanglie, Hu Hao, Huang Weijia, Hu Yu, Li .
This standard replaces the standards previously issued as follows.
--- GB 9246-1988, GB/T 9246-1996.

3 Classification and basic parameters
3.1 microscope eyepiece field number can be divided by ordinary eyepieces, wide field eyepieces and ultra-wide field eyepiece.
3.2 microscope eyepiece field of view by the aberration correction state can be divided into ordinary eyepiece flat field eyepiece. They can be divided into the objective lens has a complement
Compensation effect and no compensation (ie, independent aberration correction) eyepiece.
3.3 microscope eyepiece exit pupil distance can be divided by high eye point eyepiece and eyepiece general.
3.4 eyepiece magnification shall comply with GB/T 22059 of.
Interchangeable eyepieces with an outer diameter of 3.5 shall comply with GB/T 22132 of.
3.6 Observation eyepiece parfocal distance should comply with GB/T 22057.1 ~ 22057.2 of.
3.7 observe the eyepiece field number shall comply with the requirements in Table 1.
