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 on the stage to achieve simultaneous measurement at once.

STM7 Solution
There are four types of square measuring platforms available, namely: 50 mm × 50 mm, 100 mm × 100 mm, 200 mm × 200 mm, and 300 mm × 300 mm. Whether it is a large sample or a small sample, there is always a platform 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 metallographic objectives, and cannot simultaneously meet multiple observation requirements.

STM7 Solution

The measuring objective can be used by installing a measuring objective adapter, and after replacing it with an objective turntable, the metallographic objective 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 better 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.

Metallographic objective lens

It can achieve high magnification and high-resolution observation capabilities comparable to optical microscopes. More importantly, in addition to bright field observation, it can also correspond to dark field, polarization, and differential interference observation.

Height measurement: Focused navigation system.Realize faster, simpler, and more efficient 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.

STM7 Solution
The Olympus focusing navigation system achieves high repeatability in height measurement by projecting patterns within the field of view and allowing the operator to confirm the overlap of the upper and lower patterns. 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.
Visual height measurement, focusing on navigation system.

The advantages of automatic focusing enable fast and high 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.

STM7 Solution
Fast, * * focused, and measurement that is not subjectively influenced by the operator

Olympus has developed the STM7 series autofocus unit, which achieves fast focusing while ensuring * * focusing repeatability. Therefore, regardless of the operator's experience, height measurement can be achieved in a very short amount of time. Regardless of the operator's experience, the STM7 autofocus unit can achieve height measurement in the shortest possible 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 enables the operator to observe without leaving the X and Y handles, thereby greatly improving the measurement efficiency of the Z-axis.
