Ergonomics
Work Comfortably and ProductivelyErgonomic Instruments Enable Natural Posture, Reduced Stress, and Increased ProductivityThe ergonomic long tilting trinocular provides an optimized work position by bringing the microscope closer to the user, while the extendable eyepoint adjuster provides flexibility for users of different heights. The SZX2 series’ ergonomic instruments reduce stress during observation by providing the most comfortable position for each user, increasing work efficiency. |

Ergonomic Design Based on 3D CAD AnalysisThe microscope body and stand feature precisely curved contours developed through careful 3D computer aided design (CAD) analysis. Key ergonomic features help reduce fatigue during periods of long observation and feel smooth and comfortable to the touch. |

Precise Recall of Specific Magnification SettingsMany inspection tasks require using the same zoom magnification setting to ensure consistent and comparable results. The integrated click-stop mechanism provides quick and easy access to this important function. The zoom knob stopper enables the user to accurately choose their desired magnification, and the setting in use is clearly displayed on the front control panel. | ![]() |
Eyepieces That Reduce Fatigue and Exclude DustThe eyepieces feature a pupillary aberration control mechanism, keeping the image visible even if the operator’s eyes move. This lessens operator fatigue during long observations. The unique eyepiece mounting design excludes dust particles and keeps the eyepiece firmly in place, enabling clear images and an ergonomic eyepiece position. |
|
Electrostatic Discharge (ESD) Safe DesignAll microscope bodies and accessories are ESD-safe and can discharge static electricity from 1000 V down to 100 V in less than 0.2 seconds, helping to protect the equipment and prevent sample damage. |

Record and Store Digital ImagesEvident offers a full line of digital cameras that adapt to the SZX7. They are available as a standalone or PC-controllable system. Software packages vary from simple image capture to measurement, report generation, and database archiving. See Digital Cameras |
All-in-Focus Imaging Made SimpleReconstructing an all-in-focus image is simple in our software. Manually acquire images from the Live EFI (extended focus imaging) function to obtain fully focused views of thick, rough, or uneven samples.

Flexible Workflows from QC Inspection to Failure AnalysisPRECiV software offers a flexible workflow solution for QC inspection, materials analysis, and failure analysis. Pair it with the SZX7 and a digital camera to seamlessly acquire images, process them, and make 2D measurements. Advanced imaging and analysis functions include panoramic views, extended focus images, and particle analysis. Zoom into Efficiency
To speed up QC inspection or failure analysis work, combine the SZX7 with our SZX2-ZMS zoom magnification sensor. It automatically records the zoom magnification in your PRECiV software, enabling the correct 2D geometric measurements without the need to manually enter the magnification. From imaging to reporting, all dimensions are under control. Now you can zoom in and measure the details faster, adding confidence and efficiency to your inspections. |
