When you’re looking for a digital microscope system that will grow and adapt as your work changes, you want the Ash OMNI 3. Manufactured by Ash Technologies, the OMNI 3 offers a variety of unmatched upgrades and features you won’t find anywhere else.

Unlike other digital microscope systems, the Ash OMNI 3 is capable of processing complex imaging tasks without a PC. These images can be stored directly on the device, sent to a network location, or sent via email so they can be saved for later viewing. This fully HD microscope offers lag-free viewing, allowing the user to make adjustments to their specimen in real-time. The OMNI digital microscope offers a unique system that allows you to operate the device using a monitor with a mouse or by using the controls on the front.

These ASH digital microscopes feature a range of magnifications based on your needs. This includes an optical range of 2.5x - 68x and a digital range of 69x - 136.5 with the included 5D lens. The OMNI 3 is pre-calibrated at the factory and can track calibration across the various zoom levels.

Perhaps the biggest difference between the Ash OMNI 3 digital microscope system and other microscopes is the availability of apps that can improve your productivity, quality assurance, and much more. The apps that are available for the OMNI microscope include 2D measurement, side-by-side image compactor, object counting, and a variety of other purposes. All apps can be tried for free (30 clicks) before deciding to buy.

Omni 3 Optional Accessories

Add-On Apps
148-001 Omni Measurement & Graticule
Intuitive on-screen full 2D measurement application. Point-to-point, diameter, angle, adjustable X-Y grid, shapes and annotation features to accommodate a multitude of samples and specifications. Graticule creation allows rapid sample analysis against on-screen digital templates with tolerance limits, enabling quick go/no-go defect analysis.
148-002 Omni Image Stacking
View a sample with different layers all in focus at the same time. Omni 3 automatically captures from 2 to 12 images at different focus positions and creates a single image based on the sharpest regions from each of these separate captures. The result is one image with all features of the 3-dimensional sample in focus at the same time.
148-003 Omni Comparator Overlay
Create an image overlay of a master image (gold sample) 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.
148-004 Omni Comparator Side by Side
Visually compare your live sample image to a stored master image (gold sample) in the form of a split screen. Add notes through annotation and save the comparison image for documentation for traceability. Enables rapid identification of differences between gold sample and test samples.
148-005 Omni 3 DXF Import and Export
Import a range of DXF files to create graticules for overlay comparison with parts and samples. Imported DXF files can be edited and annotated on the Omni 3.
148-008 Omni 3 Z Height Measurement (requires CAT# 148-001)
Measure in 3D on the new Omni 3. Now you can measure in the Z axis, in addition to the X and Y axes, bringing the Omni 3 capability to a whole new dimension. Rapidly inspect your parts up to five times quicker when compared to outdated manual inspection methods.
148-009 Omni 3 Color Analysis
Advanced algorithms automatically calculate the color 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.
148-010 Omni 3 Object Counting
Automatically identify and count the number of objects within your region of interest. 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.
