What is Helium Rough scanner and who benefits

What is Helium Rough?

Helium Rough is the most accurate advanced rough cavity mapping and inclusion scanning, value based planning equipment, optimizing rough with value analysis and sawing plans.

For the first time, you have an access to a diamond planning and optimizing equipment in true sense. All earlier planning equipments will appear to be only a measuring tool.

Helium Rough is used for scanning rough and polished diamonds constructing its 3D - Model.

The tecnology includes dual laser cavity mapping system that gets to the bottom of more holes than the single laser mapping systems.

Salient Features

  1. Any inclusion including Gletz / piques / bubbles (VS to I) can be considered.
  2. Shortest payback time. Many times, as short as 4 to 5 days. Increases profit exponentially with a little increase in efforts.
  3. Automatic Sawing plan generated, to maximize your profit.

  4. Most advanced and accurate cavity mapping technique, thanks to its dual head scanning technology.
  5. The machine intelligence will help you to decide if inclusion removal or re-orientation of inclusion will maximize your profit.

  6. If the suggested plan includes the inclusion, the machine software will show you where that inclusion will be reflected in the polished piece. The Software will grade the finished stone based on size of inclusion left inside the polish stone, its orientation and its reflection / refraction inside the polish stone. Model building accuracy of better than 0.005 mm makes this possible.
  7. Intelligent Laser marking software leaves off the area unmarked where it matters the most.

  8. Very fast laser marking facility. Choose and mark all option of marking in one key stroke.
  9. Warranty of 36 months/5000 hrs on laser source.
  10. Free Oxygen Viewer will make it possible for your overseas office to participate in critical decision making. They will be able to view the provisional / final plan on the virtual stone, and give their consent before further process.
  11. Free Oxygen Viewer is an inevitable tool for the manufacturing department to have a look at virtual report of the plan. This will reduce a great amount of paper work, and makes your factory, a truly IT oriented organization.
  12. Eight options of cavity mapping: Small, Medium, Big, etc. to suite your need.
  13. LAN configurable and multi user environment software support reduces overall cost. Inclusion placement and allocation can be done in off machine mode to reduce load on the scanner and increase its utility factor (reduce overall investment).
  14. The software is specifically designed to accurately suggest the most profitable planning options in value recovery terms. In the process the Rapaport / user specific price structure can be used.

Samples of reports

Helium Rough and Pacor software allows creating and printing reports for every solution and also for every polished diamond in solution separately.

The reports are created based on templates in MS Word rich-text format (RTF). Also report data can be exported to external files for processing by third-party software.

The example of rough report:

Immersion Glass Molding Not available

Immersion Glass

In this technology, Immersion Glass material is used. Immersion Glass is the material having nearly same Refractive Index value as Diamond and is solid at Room temperature and melts to liquid at around 100C. We can heat Immersion Glass and Diamond in cubical mold so glass and diamond will become a single entity and reflections of inclusions will be removed. Due to absence of reflections, plotting on M-Box is more precise, very easy and can be done by even non-experienced operator.
