The STM6 microscopes offer excellent versatility and high performance three axis measurements of parts and electrical components, with sub-micron precision. Low magnification option makes this ideal for toolmakers.
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.
Measuring Microscopes Traceability System
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.
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.
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.
This mode provides instant focusing in the center of the field of view through the execution of the auto focus.
This mode always maintains the state in focus while moving the stage across a sample. This greatly improves the operating time.

|Objective Lens||Repeatability(2σn-1)*1||Spot diameter *2|
*1 : Indicates a value based on Olympus reference specimen.
*2 : Indicates a theoretical value by calculation.
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.
This table can perform leveling of a specimen with ease.
A digital camera can be attached to the STM6's trinocular tube. This allows recording and storage of digital images, facilitating report generation. Choose from Olympus' wide range of digital cameras based on your application in terms of image quality, functions, and operability.
