Provide a stage suitable for your sample size

Frequently Asked Questions

·Short measurement travel cannot meet the measurement needs of larger samples.

·So far, the large stage has provided sufficient measurement travel in the X-axis direction, but the Y-axis travel is still relatively small. During the measurement process, it is necessary to compensate for the Y-axis stroke that is shorter than the X-axis coverage by rotating the sample, which is time-consuming and inefficient.

·Due to the narrow measurable range, it is not possible to arrange a large number of samples instageTo achieve simultaneous measurement at once.

STM7Solution

·There are four types of square measuring platforms available for measuring stroke (50 mm x 50 mm, 100 mm x 100) mm,200 mm x 200 mm, And 300 mm x 300 mm). Whether it's a large sample or a small sample, there is always a stage that will be suitable for the sample you want to measure.

·The use of a clutch system allows for quick switching between coarse and fine tuning. With this switching function, the stage can also quickly move along the X-axis and Y-axis directions, and can freely shuttle on the XY plane.

·A 300mm long square stage can provide the same measurement stroke in both the X-axis and Y-axis directions, which means that all measurements of large samples, such as 300mm wafers and printed circuit boards, can be achieved without rotating the sample.

Observe at low and high magnification using the same microscope

Frequently Asked Questions

·Most traditional measuring microscopes can only measure objective lenses or metallographyobjective lensUnable to meet multiple observation requirements simultaneously.

STM7Solution

·STM7 can use a measuring objective by installing a measuring objective adapter, and after replacing it with an objective turntable, metallographic objectives can be used. This means that STM7 combines both metallographic optical system and measurement optical system in one measuring microscope. Through this method, whether measuring large or fine samples, or samples with large surface height differences, the STM7 series can correspond to and assist users in selecting observation methods.

Measuring objective lens

Due to the very long working distance of the measuring objective, there is no need to worry about contact between the objective and the sample when focusing on samples with large surface undulations. In addition, with the low magnification capability of the measuring objective, a larger field of view can be observed at once.

Can obtain andoptical microscopeComparable high magnification and high-resolution observation capabilities. More importantly, in addition to bright field observation, it can also correspond to dark field, polarization, and differential interference observation.

A light source manager that greatly improves observation and measurement efficiency

Frequently Asked Questions

·The traditional measurement microscope's analog knob adjustment method cannot achieve quantitative control of light intensity. In this way, the light intensity during each measurement cannot remain consistent, resulting in changes in the measured values.

·When using traditional measuring microscopes, it is necessary to adjust the light intensity every time the objective is switched, which makes the workflow very inefficient.

STM7Solution

Digital display that can quantitatively grasp the brightness of light sources

The light intensity of STM7 can be quantitatively displayed, which ensures that observation and measurement are always carried out under the same conditions.

When switching the objective lens, there is no need to manually adjust the light intensity

The repeatability of the autofocus system

Realize faster, simpler, and more accurate height measurement

Frequently Asked Questions

·When conducting visual measurements, different operators will obtain different height measurement values. In addition, this measurement method is very time-consuming and inefficient.

STM7Solution

A focusing system with superior repeatability, simplicity, and high precision

By projecting the pattern within the field of view and having the operator confirm the overlap of the upper and lower patterns, Olympus' focused navigation system achieves highly repetitive height measurement operations. When conducting height measurements through ordinary visual observation, even images that appear very clear and in focus may have slight errors. By using the STM7 focused navigation system, measurements can be made simply by matching the markers, thus reducing the subjective impact of the operator on the measurement results.

The advantages of automatic focusing enable fast and high-precision height measurement

Frequently Asked Questions

·When conducting visual measurements, the height measurement results obtained by different operators may also vary.

·Manual height measurement requires the operator to repeatedly move the stage and use a knob to focus, which makes the measurement both time-consuming and inefficient.

·It is difficult to focus on small objects, such as wires.

STM7Solution

Auto focus unit: excellent reproducibility and focusing speed

Regardless of the operator's experience, the STM7 autofocus unit can achieve highly accurate height measurement in a short period of time. Even rough or tilted sample surfaces can be stably focused using active reflection and confocal methods, while small-diameter lasers can ensure automatic focusing on small objects such as leads.

Single focus mode

After performing autofocus, it can instantly transition from a rough focus state to a clear focus at the center of the field of view.

Tracking mode

After enabling the distinctive tracking mode, it will automatically focus according to the ups and downs of the sample surface, even when moving the worktable, it can always maintain a focused state. This allows the operator to observe without leaving the X and Y handles, greatly improving the measurement efficiency of the Z-axis.

Accessories for expanding observation and measurement range

A system designed specifically for more advanced measurements

Measurement Support System

For displaying the data and images output by a measuring microscope, the clearer the view, the more convenient and efficient it is to use and measure. The development of the all-new Olympus is driving the realization of complex measurements with higher precisionmeasurement softwareThe reason lies in. This software can also be used in conjunction with digital cameras.

After placing the sample, measurement can begin - there is no need to align the sample in parallel

direct measurement

Accept coordinate information output by STM7 for measurement.

Call measurement again

The coordinates obtained after measurement or calculation can also be used for subsequent measurements. This avoids duplicating the same work, thereby achieving a smoother and more efficient workflow.

Virtual point measurement

By drawing straight lines and circles, intersection points, midpoints, lengths, and a series of other measurement items can be formed, which can then be retained as reference points on the collected sample images.

Alignment measurement

The origin and X-axis can be set according to the sample, so that measurements can be taken even when the sample is not aligned parallel to the stage.

Original axis, new axis

XZplane surveying

Traditional measuring microscopes mainly focus on measuring the XY plane when viewed from above. In response to users' demand for measuring cross-sectional direction from a side view perspective, Olympus has built-in the XZ plane measurement function in the STM7-BSW. Measurements that were previously difficult to implement have now become much easier - such as measuring the radius of a hemispherical object's vertical cross-section, or measuring the depth of a groove with a curved bottom compared to a reference line.

Measurement of the height between the bottom of the groove and the reference line for measuring the radius of a hemispherical sample

Record the steps for repeated measurements

Macro registration

Frequently used alignment and other measurement steps can be combined and defined as a single macro button, so that there is no need to start from scratch after each microscope startup.

Repeat measurement execution

By simply moving the stage and obtaining coordinate values according to the instructions in the recorded teaching list, it is easy to perform repeated measurements and complete all assignments. This function can be used to repeatedly perform the same measurement items on samples of the same type. In addition, if set values and tolerances are set in the recorded teaching list, the software can automatically determine when the measured value exceeds the specification.

NG result example

Navigation of measurement points for repeated measurements

This function can display the direction and distance of moving to the next measurement point, thereby eliminating the operator's distress in this process. This function also eliminates the trouble of confirming the next measurement point on the drawing before each movement, and improves the speed of the operator's operation when repeating measurements.

Convenient function that can eliminate the subjective influence during the measurement process

Automatic edge detection

This function detects the edges of the sample, automatically obtains the coordinates of the sample, and measures them. Therefore, the operator no longer needs coordinates, reducing the subjective impact of the operator on the measurement. Another feature of automatic edge detection is its timed function, which automatically obtains coordinates after a specified time. The timing function and foot switch function enable the operator to concentrate on measuring without leaving the handle of the loading platform.

Multi point automatic edge detection within a circle

Outlier elimination

During the edge detection process, abnormal points such as metal burrs can be automatically excluded. In this way, regardless of the state of the sample, consistent measurement and calculation results will be obtained. In addition, the excluded outliers can also be displayed on the screen in different colors.

Abnormal point elimination function for samples with abnormal points

lighting control

The intensity of microscope illumination can also be precisely controlled through software. When registering a teaching list for repeated measurements, the setting of light intensity can also be saved, so that measurements can be carried out under the same lighting conditions during repeated measurements or automatic edge detection processes.

Automatic magnification recognition (optional, only applicable to the configuration of encoding objective disc)

By using the coded objective dial, the previously set calibration values can be automatically recalled when switching objectives. This can always display the appropriate scale on the monitor.

Generate customized reports

One click report generation

The measurement results can be output in Excel format with just one click, which avoids the possibility of errors during data recording. Images can also be pasted together with measurement results, thereby achieving more efficient report generation.

Optional feature: Multi Image Splicing (MIA) function

Splicing multiple images can obtain a wide area image with high magnification. Because images are pieced together based on coordinate data, the system is able to generate highly reliable images.

Optional feature: Depth of Field Expansion (EFI) function

For samples with uneven and complex surface shapes, the EFI function can effectively capture images with good focus throughout the entire height range. When using EFI function, move the Z-axis to obtain multiple images with different focal positions, then perform image processing and merge them into one fully focused image. If an electric Z-axis module is used, one click automatic image synthesis can be achieved.
