The STM6-LM microscopes equipping a 250 x 150 mm stage 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.
Electronic System Integrated Body
|The main unit incorporates both the counter and electronic system to improve the foot-print and ease of use. This model also incorporates an RS-232C interface for data communication to facilitate data transfer to a PC or other external devices such as a printer.|
Clutch-type Large Stage
|Olympus 250 x 150mm equipped stage provides a large measuring range of 250 x 150mm with a clutch engage/disengage mechanism that allows quick changeover between coarse and fine movements with a single touch of a lever. Flexible stage movements in all directions allow even large specimens to be quickly and accurately inspected. Alternatively it is possible to measure multiple specimens set on the same stage.|
|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
|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.|
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 adjustment. 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.
Z-axis Control Box
|The integrated counter is mounted on the microscope body, with the display unit located at eye-level height for simple observation. The operator can thereby confirm a measuring value with only a slight eye movement, allowing concentration on the specimen under observation.|
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. The LED illumination is also free from flickering and brightness fluctuation, reducing eye fatigue even over extended periods of operation.
|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.|
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.

*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.

Reflected Illumination Units
|Three types of reflected illumination units are available to support a variety of measuring ranges. These illumination units are capable of brightfield, darkfield, or differential interference contrast observation, corresponding to measuring objective lenses or metallurgical objective lenses with revolving nosepiece.|

White LED Illumination Unit
*The model of the LED illuminator may vary with area.
|This white LED light source unit features a long service life, power savings, a reduction in size and weight, and high performance with no flickering or brightness fluctuation.|
4-divided LED Illumination Unit
|This reflected LED ring-light illuminator that provides high color temperature and clear images. This unit provides 4-divided independent illumination and allows you to select an optimal illumination mode from among a total of 13 patterns.|
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 rang of digital cameras based on your application in terms of image quality, functions, and operability.
Geometric Calculator MM-CAL22
*MM6-CAL22 may not be available in some area.
|This measuring microscope can start measurement immediately after placing a specimen on the stage due to the unnecessity of parallel alignment between the specimen and the stage. Two-dimensional arithmetic processing can be performed simply by entering pieces of point data, displaying the descriptions of alignment item and measuring item during measurement on the display unit. Also, measurement results are outputted from the built-in printer.|
