Inverted Microscope for Weld Analysis and Documentation

High-resolution, ergonomic inverted 4K optical system with x26:1 motorised zoom, and precise auto-focus designed for performing accurate weld bead analysis, measurement, and documentation with minimum efforts.

Developed for Ease-of-Use

Turn on the WELDinspect, start INSPECTIS© or NIS-Elements software and place the prepared sample on top of the device. The pre-calibrated inveted microscope ensures that the sample is imaged brightly for analysis and instant measurements.

Dedicated Weld Bead Masurement Software

Powerful and customizable Nikon Metrology NIS-Elements software with user-friendly sequential measurements, pre-defined weld templates and
step-by-step instructions.



Easy to Use

Superior Optical Performance

Outstanding 4K image quality, wide zoom range and large Field of View ~ 82 to 3.1 mm (~3.23” to 0.12”), equivalent to ~2.6x to 68x optical magnification or ~7.5 to 196x on screen magnification.

Upgradeable with x35 zoom optics providing ~ 58 to 1.65 mm (~2.28” to 0.063”) FoV, equivalent to ~3.8x to 127x optical magnification or ~10.9 to 370x on screen magnification.

Robust Desgin

The robust aluminium housing with heavy duty steel base-plate and stainless-steel top-plate creates maximum stability and robustness even in harsh environments.

The tempered glass window is specially manufactured to stand scratches and is coated to minimises glare and back-reflection into the optical system.

A cover is included for protection of the device aginst dust when not in use.

Dedicated Software

Nikon NIS-Elements combines powerful image acquisition, analysis, calibrated sequencial measurements, visualisation and data sharing tools.

Pre-calibrated optics with automatic zoom tracking ensures quick and accurate measurements of welds. Built-in camera and lens controls with 8 quick access zoom buttons makes image adjustment and acquisition simple and intuitive.

Fast and Accurate Sequential Measurements

User-friendly controls combined with pre-defined common weld type templates and streight forwards step-by-step sequential measurements ensure quick and accurate measurements.

User definable measurement sequences according to individual standards and acceptance criteria in addition to the pre-defined templates.

Data Export and Report

Export finished measurements inclusing sample pictures as a group to a Report, Microsoft Excel, Clipboard or a File format. The report can further be saved as PDF.

The measurement definition and the report can be edited and re-designed according to your needs.
