|Microscope stage is usually located under the objective lens of the microscope to place the object to be observed. Usually, it is equipped with mechanical motion devices, and is moved and positioned in XYZ three directions or rotates or tilts around the Z axis and other functions.
Microscope stage usually has a function of moving in the XY horizontal direction, and is required to be perpendicular to the optical axis of the microscope Z direction in the XY horizontal direction.
XY Measurement Stage
|The XY measurement stage refers to the stage with a measuring mechanism in the XY horizontal direction, and it requires that the stage has relatively high accuracy. The stage not only has a flatness requirement on the surface, but also needs to ensure that in measurement the XY plane is always in a horizontal position during the movement.
For the XY measurement stage, especially when observing and measuring the observed object beyond the field of view, the stage can be moved, and reading can be carried out through an externally attached measurement device to measure accurately large sized objects.XY Stage Measurement Method
For XY measurements, a crosshair is required within the measurement field of view for aiming and positioning.
The crosshair can be obtained by various means, generally on the eyepiece, using the preset reticle method, which is the simplest method.
When using the monitor screen for measurement, a cross reticle can also be used, which is placed in the photographic eyepiece optical system. This method is simple and practical, the reticle is relatively clear, and various patterns of reticle can be used. It is also convenient to adjust the alignment angle of the reticle in the eyepiece.
At present, more and more measurements use the crosshair function in the camera. The crosshairs are displayed by splicing the pixels of the same color, and even the color can be selected so that it is clearly distinguished from the background pattern, making the crosshairs more conspicuous and easy to operate. Some cameras have crosshairs that can also add multiple sets of lines, and can move horizontally and vertically so as to combine a variety of rectangular patterns of different sizes. One can apply and mark the position and size of the observed specimens. In industrial processing, it has the profilometer and projector functions.
In addition to the camera to obtain the crosshair, there is also method of using a crosshair generator, display and other devices to obtain crosshair.
During measurement, first place the object to be measured on the center position of the field of view of the stage, adjust the clear image, open the crosshair, and then move the object to be measured to the starting position to be measured, so that the center intersection of the crosshair is aligned with the said position, turn on the scale 0 position (or note the reading position), then move the object to be measured in the X or Y direction until the end point of the measurement position, then stops, and finally read through the measuring scale.
Measurement error in XY horizontal direction
For XY stage measurement, it is necessary to use a high-magnification objective as much as possible.
For XY horizontal measurement, when measuring objects with shorter lengths, this error is very small, even negligible. If the measured object is relatively long, the bigger the angle at which the stage is tilted, the greater the differential value between the oblique line of the measured image and the actual horizontal line segment of the object, and also the bigger the accumulated error will be.
Ways to adjust the level of the XY stage:
If the stage is unable to maintain horizontal, after the initial position is focus adjusted to get a clear image, the image will become more and more blurred, and in most cases, the stage is tilted to one side (up or down). To solve this problem, adjust the height of the four feet of the stage, or adjust the height position of the screws at the four corners of the bottom glazing of the stage center to keep the stage horizontal.
Using a line ruler can also calibrate whether the distance traveled by the line ruler at each grid value for measurement is consistent with the distance read by the stage drive (for example, the reading from the micrometer or the digital display), thereby calibrating the error of the stage movement accuracy. Such errors are often caused by the empty return of the stage drive or the insufficient of stage stiffness etc.
Stage Backlight Window Size
|Stage backlight window size refers to the size of the window through which the transmitted light passes under the stage on the XY table plane of the stage.
This window is usually covered with a piece of glass. For some stages with accuracy requirements in the XY horizontal direction, the horizontal plane of the glass can be adjusted by the height of the screws on the four corners below, and the consistency with the height of the stage plane is guaranteed.
XY-Axis Measurement Mode
|The XY-axis measurement mode refers to the way the scale used when measuring the XY axis of the stage. For different system, the choice is also different according to the different accuracy and operation requirements, such as mechanical micrometer, capacitance digital display, encoder and so on.|
|After unpacking, carefully inspect the various random accessories and parts in the package to avoid omissions. In order to save space and ensure safety of components, some components will be placed outside the inner packaging box, so be careful of their inspection.
For special packaging, it is generally after opening the box, all packaging boxes, protective foam, plastic bags should be kept for a period of time. If there is a problem during the return period, you can return or exchange the original. After the return period (usually 10-30 days, according to the manufacturer’s Instruction of Terms of Service), these packaging boxes may be disposed of if there is no problem.
