Increase efficiency by 70% whilst eliminating human error.

Significantly reduce the time spent manually counting parts while reducing costly overheads. Report generation is quick and simple for easy documentation and traceability.

Colour Analysis App

Advanced algorithms automatically calculate the colour value of any sample.

Identify contaminants or foreign objects within your sample. Eliminate human error and improve yield by up to 50%.

Reports can be generated for easy documentation and traceability.

Powerful New Features and Benefits


Enhanced AshCal™  Calibration Technology continually maintains calibration at all magnification levels, removing the need for manual re-calibration, saving time and increasing efficiency.

AshCal™ is unique to ASH systems.

OMNI 3 is factory calibrated before shipping.

Super Fast Auto-Focus

Place the sample under the Omni 3 and it will immediately focus on your part throughout the inspection process.

Inspect your parts up to three times faster.

Quickly and seamlessly inspect your part without having to adjust manual focus or change the height of the part.


Quickly focus on the area of interest by simply using the mouse pointer.

Increase speed, improve accuracy and reduce human error with the capabilities of SpotFocus™.*


*Patent Applied for.

Manual Rocker Focus

Use Manual Rocker Focus to accurately adjust the focus level to your region of interest.

Save time by quickly adjusting the focus level using the rocker icon to inspect specific regions on an object when in manual focus mode.

Superb Image Quality

Superb Image Quality

No Video Latency

There is zero delay between movement under Omni 3 and what you see on the screen, resulting in a more efficient inspection process.

Omni 3 is 3x times faster than our previous systems.

View parts in real time with no video lag, allowing you to comfortably inspect, rework, modify or assemble anything.

Advanced Camera Settings

The new Advanced Camera Settings gives the user more power and control to enhance the image for a wide range of inspection and measurement capabilities.

Ensure image quality exceeds your needs.

Unlock the full potential of Omni 3 by fine-tuning sharpness, contrast, saturation and camera shutter speed to suit your specific requirements.

Improved DoF

Improved Depth of Field (DoF)

The Omni 3 has improved depth of field, making inspection much faster and more efficient without the need for changing focus positions or adjusting camera height.

The Omni 3 maintains the following improved great apps introduced with the hugely successful Omni core.

2D Measurement, Annotation & Graticules

Intuitive on screen full 2D patented measurement application. Simply draw measurements, shapes and add annotations onto a live or static image and save direct to internal memory or external storage options. Features include: point to point, diameter, angle, adjustable X-Y grid, shapes and annotation to accommodate a multitude of samples specifications.

Graticule creation allows samples to be analysed against on-screen digital templates with set tolerance limits. It also enables quick go/no-go defect analysis. This improves efficiency in high-volume sample through-put inspection.

Image Stitching

Stitch multiple images together, increasing your field of view at high magnification. Document and annotate for traceability.

DXF Import

Import a range of DXF files to create graticules for overlay comparison with parts. Imported DXF files can be edited and annotated on the Omni system.

This dramatically reduces time taken to create graticules and increases workflow efficiency.

Image Stacking

View a sample with different layers all in focus at the same time. Omni automatically captures several images from 2 to 12 at different focal depths and creates an image based on the sharpest regions from each of these separate captures.

Comparator Overlay

This app allows the user to create an image overlay of a master image to identify defects by overlaying and flashing the live sample image against the stored master image.

Enables rapid identification of differences between gold sample and test samples.

Improved accuracy and usability in addition to improved workflow speed.

Comparator Overlay

This app allows the user to create an image overlay of a master image to identify defects by overlaying and flashing the live sample image against the stored master image.

Enables rapid identification of differences between gold sample and test samples.

Improved accuracy and usability in addition to improved workflow speed.

Comparator Side by Side

Visually compare your live sample image to a stored master image in the form of a split screen. Add notes through annotation and save the comparison image for documentation and traceability. Enables rapid identification of differences between gold sample and test samples.

The Omni 3 maintains the following improved great features introduced with the hugely successful Omni core.

intuitive mouse

Intuitive Interface

Intuitive mouse and keyboard GUI for simple and familiar user experience.




Save time by emailing directly from Omni. Document directly to server or cloud network for traceability.

The Omni 3 digital microscope has been engineered from the inside out to deliver one of the most advanced and intuitive digital microscope experiences ever. We carefully studied how people use digital microscopes and listened to their feedback. This has led to multiple innovations including:

  • Powerful embedded digital microscope software which can process complex imaging tasks without a PC.
  • This software can be upgraded and expanded to increase functionality.
  • Intuitive software interface allows anyone to quickly inspect and perform patented measurement.
  • Omni hardware is custom designed to deliver maximum power in the smallest possible form factor.
