High Measuring Accuracy and Durability

High-rigidity Body and Stage Resistant to Atmospheric Changes

STM6 FEM Analysis of microscope body FEM Analysis
Maintaining accuracy is of paramount importance in any measuring instrument. In addition, retaining rigidity over long periods of time is crucial for reproducible measurements. Olympus has developed a high-rigidity body and precise stages that are resistant to atmospheric changes. The adoption of a linear guide mechanism and the incorporation of an original linear scale allows Olympus to meet the measurement needs of client with high reliability.

Optical Linear Scale that Provides Sub-micron Resolution

STM6 Optical Linear Scale Optical Linear Scale
Scale accuracy is a key point to determine the accuracy of a measuring microscope. The STM6 electrically processes and measures the optical information obtained through Olympus’ optical linear scale.

Traceability System to International Standards

Olympus maintains the highest-level environment throughout the stages of production and assembly to ensure high precision. At our temperature-controlled plant, skilled Olympus engineers perform high-precision machining of carefully selected component materials, delicate finishing processes and final adjustments. All component parts and completed products are fully controlled under a rigorous traceability system.

The STM6 was Designed with Emphasis on Ease of Use

Motorized Focus Unit Available for Quick Z-axis Measurement

The STM6 has adopted a motorized focus unit that significantly improves operability when focusing and measuring a height or depth. 5 step control over the speed of the vertical Z motor, greatly reduces fatigue during operation.

Counter Located at the Ideal Observation Position

STM6 Integrated Counter Counter
The integrated counter is mounted on the microscope body, with the display unit located a eye-level for simple observation. The operator can thereby confirm a measuring value with only a slight movement of the eye, allowing concentration on the specimen under observation.

UIS2 Optical System and LED Illumination Enhances Edge Detection

The STM6 employs Olympus’ UIS2 optical system that achieves superior resolution and contrast, and LED illumination that delivers faithful color reproduction independent of changes in brightness. This greatly improves the detection of edges, thus resulting in dramatic improvement in measurement repeatability. The LED illumination is also free from flickering and brightness fluctuation, reducing eye fatigue even over extended periods of operation.

Reticles are Used for Easy Positioning

Reticle Reticle
Accurate alignment between the object being measured and the reticle is critical to any measuring microscope. In straight-line alignment, the use of a reticle and a dotted line will produce more accurate results than using a single line. Olympus has further improved alignment accuracy by using a reticle and a dotted line on the focusing plate.

Automated Focusing System Provides Superior Repeatability

High-accuracy Auto Focus System (available as an option)

This laser-based focus system provides two modes of functions: one-shot and trace. Visual measurement of a height or a depth, which requires subtle operations, can be automated by selecting either mode. This significantly improves the efficiency and reproducibility of Z-axis measurements while allowing continued observation while using both hands on the stage control knobs.

[One-Shot Mode]
This mode provides instant focusing in the center of the field of view through the execution of the auto focus.

[Trace Mode]
This mode always maintains the state in focus while moving the stage across a sample. This greatly improves the operating time.

Focus Navigator Achieves High-accuracy Height Measurement and Increased Reproducibility

Olympus Focus Navigator system improves reproducibility during focusing by aligning the vertical displacement of the index pattern projected on the specimen. The focus navigator improves the repeatability in height measurement and reduces measurement variations due to personal difference, compared with visual focusing. The index pattern is compatible with various specimens simplifying focusing to contribute a dramatic reduction in measurement time. The Focus Navigator unit is compatible with reflected brightfield and reflected darkfield observations with objective lenses of 10x through 50x.
