Whether samples are small or large, complex or straightforward, or a novice or an expert is taking measurements, the Olympus STM7 range features measuring microscopes tailored to fit your needs.
Refined Optical Performance
The STM7 series uses the same UIS2 infinity-corrected optical system found in state-of-the-art optical microscopes.
As a result, observed images have high resolution and high contrast, with aberration thoroughly eliminated to help ensure highly accurate measurement in minute detail.
Reliable Measurements with a Stone Stage-Mounting Plate
The STM7 series uses a highly durable, vibration-resistant frame with a granite surface plate to improve measurement accuracy further. This stability enables sub-micron level measurements with minimal error.
User-Friendly, High-Precision, 3-Axis Measurement
As modern manufacturing technology becomes increasingly miniaturized and precise, highly accurate measurements are even more essential along the XY axis and the Z-axis. Olympus responded by creating the first reflective active, confocal autofocus system.
Dependable Quality Based On a Strict Traceability System
A strict traceability system controls the accuracy of Olympus’ measuring microscopes, and Olympus even offers traceable calibration at installation.
Calibration certificate issued by Olympus Corporation Test & Analysis Center, and authenticated by ILAC-MRA calibration accreditation agencies (JCSS, JAB).
Traceability systems vary depending on periods and countries/regions. The samples used in STM7 calibrations are calibrated in each country/region. Please ask Olympus for details.
Operability
Stages that Fit Your Samples
Common Problems
Short measurement stroke precludes the measurement of larger samples
Samples must be rotated because the X-axis measurement area is shorter than the Y-axis measurement area
Due to the narrow measurement range, it is impossible to line up large numbers of samples on the stage to measure them at the same time
STM7 Solutions
The STM7 features a 300 mm x 300 mm stage capable of measuring large samples, including 300 mm wafers and printed circuit boards.
The X- and Y-axis measurement areas are equally long, eliminating the need to rotate samples
Long measurement areas for both the X and Y-axis allow multiple samples to be lined up on the stage for more efficient measurement
Maximum Measurement Stroke 300 mm x 300 mm
Three stages are available, each with a different measurement stroke - 100 mm x 100 mm, 200 mm x 200 mm, and 300 mm x 300 mm. Whether your samples are large or small, we offer a stage that fits your application.
STM7-CS100 (100 mm x 100 mm)
STM7-CS200 (200 mm x 200 mm)
STM7-CS300 (300 mm x 300 mm)
Faster, Simpler, More Accurate Height Measurement
Common Problems
When doing visual measurement, variations can arise in the height measurements between different operators. Furthermore, this measurement method is time-consuming and inefficient
STM7 Solutions
The STM7 focus navigation system reduces the operator's subjectivity in height measurements. It also shortens the time required to perform height measurement to achieve greater efficiency
Measuring Objectives
The objective’s long working distance helps you be confident when focusing on samples with significant peaks and troughs. It minimizes the chance that the aim comes in contact with the sample.
Furthermore, their low-magnification capability enables broad areas to be observed in a single view.
Metallurgical Objectives
Metallurgical objectives enable high-magnification, high-resolution observation comparable to that of optical microscopes.
Moreover, these objectives can be used for brightfield, darkfield, and DIC observation.

Revolutionary Control Unit Refines Usability
Common Problems
Additional functions require additional operational units. Operators can’t always locate the corresponding unit quickly, which significantly reduces measurement efficiency
Numerous operational units and their power supplies around the central unit occupy valuable working space
STM7 Solutions
Almost all measuring microscope operations can be efficiently completed on the nearest operational unit
The system requires only a single operational unit and power supply, regardless of how many functions are added, freeing up workspace
Controllers
With the STM7 series, a single controller can perform virtually all measuring microscope operations, including readout reset, illumination control, focusing, and autofocus. The unit can be placed wherever you wish and operated efficiently with one hand for efficiency and convenience.

Parts mounting position measurement of O2 sensor
O2 Sensor
1. Background
A vehicle’s overall quality is equal to the sum of its parts, and it is imperative for manufacturers to maintain rigid standards of excellence for every component. Manufacturers must also take into account requirements such as emission reduction, fuel efficiency, long-term durability, and regulatory standards. The increasing complexity of auto parts and components also requires manufacturers to place a strong emphasis on material characteristics, fitting tolerances, and technical cleanliness, which all play a strong role in the long-term durability, durability, and life-expectancy of the final product.
2. Application
O2 (oxygen concentration) sensors require higher-density and more accurate measurement than any other type of vehicular sensor. Rod-shaped ceramic heaters are inserted into tubes several millimeters wide and secured into position, and failure to position the heater accurately can result in sensor deterioration.
3. The Olympus solution
Olympus STM7 measuring microscopes are equipped with field lenses to allow an operating distance of approximately 60 to 50 millimeters, and are capable of acquiring sample visualization spanning from low-magnification, wide field imagery to high-magnification spot imagery. Dedicated calculation software provides automatic edge identification to eliminate measurement errors while offering multiple measurements to facilitate accurate mounting status digitalization.
