Omni core: FAQ

Do I need a PC and software to capture images?

No, there is no requirement for a PC. The Omni core captures images direct to an internal storage memory (10GB), USB memory stick (up to 4 USB ports) and to a network or cloud server. 

What format are images captured in?

The Omni core captures files in 24 bitmap file and Jpeg format at a resolution of 1920 x 1080p. This is saved to an internal image capture software. It can also be saved to a removable USB. 

How does the Omni core save measurement files?

Omni stores proprietary measurement files in Vector format. The advantages of this are allowing the user to save their work at any point. The user can then choose to continue again from where they left off at their own convenience. 

What is the port on the Omni core used for?

The Omni core can connect to a PC through the mini USB port. Omni files can now be transferred to a PC hard-drive. The HDMI to HDMI cable is provided with the Omni unit. 

What monitor can be used with the Omni core?

Ash recommends a monitor with a minimum resolution of 1920 x 1080p to achieve optimum image.  Monitors can be purchased as an additional accessory with the Omni core. Please contact Ash or your local distributor for details of our recommended monitors.

Please note: during initial set-up of your Omni unit, please select the monitor size that you will be using. 

How is magnification calculated?

Magnification is a combination of both the objective lens used and also the monitor size. The Omni core displays the current magnification on-screen, which can be configured for different objective lenses and monitor screen sizes. Ash Technologies’ quoted magnifications are based on a 24″ monitor. 

How long does it take to set-up the Omni core?

Out of the box, the Omni core takes less than 10 minutes to set-up. Each order comes with an easy to follow User Manual and Quick Start Guide.

Do I need training before using the Omni core?

No, you will not need extensive training to utilise the Omni core’s full system features and apps. The Omni core has intuitive controls which make it easy to use from the start. Our Omni User Manual Guides are there for all of your queries, big or small. Please contact us if you require training help with installation and training.

Can I attach filters to the objective lens?

Yes. The objective lenses each have a standard 58mm thread to accept a range of filters (neutral density, colour, UV and polarisation). 

What illumination options are available?

Omni core illumination accessories are highlighted below:

  • Controllable UV Ring Light (AI 801-421), providing optimum shadow-free illumination for a wide range of applications with no external power supply. This is particularly useful for the application of conformance coating of PCB’s. 
  • Omni Diffused LED Dome Light (AI 100-045) provides light intensity control and reduces glare with no external power supply.

  • Polarised Ringlight & Analyser (AI 801-423) The Polarised Ringlight & Analyser aids the visual inspection of shiny or reflective parts. By simply rotating the Lens Polarising Filter (Analyser), the user can increase or decrease the amount of contrast in the image to highlight defects.
  • Substage Polarising Film (MR 801-835): The Sub-Stage Polarising Film is used in conjunction with the Polarised Lens Filter (Analyser). This accessory will aid the user to analyse surface or stress defects when inspecting transparent samples. The Sub-Stage Polarising Film aids visual inspection of transparent parts. By simply rotating the Polarised Lens Filter (Analyser), the user can increase visibility of surface defects.
  • Polarizing Lens (Analyzer) 58mm (AI 100-041): The Polarizing Filter helps manage reflections, or suppress glare and is extremely useful for inspecting transparent or reflective objects (when used in conjunction with polarized lighting).
