The Evident/Olympus STM7 range features measuring microscopes that can be customized to meet user requirements, regardless of the size, complexity, or type of samples being analyzed.
Refined Optical Performance
Modern optical microscopes have the same UIS2 infinity-corrected optical system as the STM7 series.
As a consequence, aberration is completely removed from observed pictures, resulting in high resolution and high contrast images that can be measured with extreme precision.
Reliable Measurements with a Stone Stage-Mounting Plate

The STM7 series features a very resilient, vibration-resistant frame with a granite surface plate to further increase measurement accuracy. This stability enables sub-micron level measurements with minimal error.
User-Friendly, High-Precision, 3-Axis Measurement

Highly accurate measurements are even more important as modern manufacturing technology gets smaller and more precise; this applies to both the XY and Z axes. In response, Evident/Olympus developed the first reflective active, confocal autofocus system.
Dependable Quality Based on a Strict Traceability System
A stringent traceability system strictly regulates the accuracy of our measuring microscopes, and Evident/Olympuseven provides traceable calibration at the time of installation.
- Traceability systems differ according to eras and nations/regions. Each nation/region calibrates the samples used in the STM7 calibrations
- Certificate of calibration from the Evident/Olympus Corporation Test & Analysis Center, verified by the ILAC-MRA calibration accreditation organizations (JCSS, JAB)
