An auxiliary observation platform is arranged above the objective table, and an observer can observe a sample to be measured through a dial above the auxiliary observation platform. The dial is provided with a coordinate system, and the coordinate system corresponds to coordinate values, so that the coordinate values corresponding to the observation points can be directly recorded when a sample to be measured is observed. When the sample to be detected is moved for the second time or the sample to be detected is taken down and then put back again, the position of the observation point recorded before can be found only by searching the coordinate value corresponding to the observation point recorded before.

Since the sample to be measured is calibrated in the coordinate system in the scale. Therefore, when the sample is observed for the first time, the endpoint of the sample to be detected can be aligned with a certain fixed point coordinate on the coordinate system, so that each observation point on the sample to be detected has a corresponding coordinate value. Even if the placement direction of the sample to be observed is changed, when the sample to be observed needs to be observed again, the endpoint of the sample to be observed can be realigned with the fixed-point coordinates, and each observation point position on the sample to be observed can be found back again according to the coordinate value recorded during the initial observation.

The sample to be measured has a predetermined size, which may be a sample having a standard size, and the dial is provided with a coordinate system on which coordinate values are provided.

The dial can be made of transparent organic glass or other materials, and the utility model is not limited in particular. An observer can observe the sample to be detected through the transparent dial when observing the sample to be detected by using the lens device, and can record the position of an observation point on the sample to be detected according to the corresponding coordinate value on the coordinate system arranged on the dial. The coordinate system can be a two-dimensional plane rectangular coordinate system formed by mutually perpendicular X-axis and Y-axis, and can also be a two-dimensional coordinate system in other forms, such as polar coordinate, natural coordinate system, etc., according to the shape of the sample to be measured. Preferably, a two-dimensional rectangular plane coordinate system formed by mutually perpendicular X-axis and Y-axis is established to facilitate the reading of data by the observer.

The dial is provided with a calibration area for setting a coordinate system, and the length and the width of the calibration area are equal to those of the sample to be detected.

The end of the sample to be measured may be aligned with the end point values of the coordinates when the observation is first made. Therefore, when the placing direction of the sample to be detected is changed, the sample to be detected can be aligned with the end point value in the coordinate system region by referring to the coordinate system, the sample to be detected can be readjusted to the previous placing direction, and then the previous observation point position can be quickly found according to the adjusted coordinate value.

The origin of the coordinate system can be set at the central position of the coordinate system, and can also be set at any position, in principle, any observation point position on the sample to be measured needs to be calibrated in the coordinate system, so that any observation point position has a coordinate value corresponding to the observation point position, and the position of the origin is not particularly limited. During observation, the origin of the coordinate system may be aligned with an end point of the sample to be measured, so that the origin of the coordinate system is used as a reference, and during next observation, the origin of the coordinate system is also aligned with an end point of the sample to be measured, so that the coordinate values of the observation point positions on the sample to be measured are the same as the coordinate values of the observation point positions at the same position of the sample to be measured before the second movement.
