To use this feature, you must have the appropriate hardware: Helium Crown Reflect and Helium Pavilion Reflect scanners. |
Reflect Scan is a technology that uses reflection imaging to achieve greater precision than the one provided by the Shadow Scan. Reflect scanning requires two separate hardware pieces and two stages of operation:
To run the shadow scanning of the whole stone and the reflect scanning of the pavilion, perform the following steps:
select the appropriate cutting type from the predefined list
expand the list, then, use of the samples from the Samples section or click to load a new sample
A sample can be loaded from a file ( *.dmc , *.mme , or *.gem ). Once loaded, it remains in your list of models (see Models management ) under the name Sample. |
Under Precision, select the desired precision.
HPOxygen stores the most recent precision setting for each particular cutting type separately. The stored precision setting is applied automatically whenever the cutting type selection is changed. In a typical workflow, it is recommended to scan round brilliants with 400 contours and Princess cuts with 800 contours since the latter cutting contains more facets with a nearly similar orientation which requires higher precision to resolve.
Note that you may also enter a custom number of contours. This requires switching the panel to Advanced mode with the dropdown switch down below:
To perform shadow and reflect scanning sequentially, check Use Reflect.
Alternatively, you can perform shadow and reflect scanning separately: uncheck Use Reflect, then use the Shadow scan, then Pavilion Reflect Scan buttons separately. |
Some post-scan operations may be initiated via the Scan & Build section. Switch between Basic and Advanced set of operations using the button at the bottom of the section. Operations are the same as for Shadow Scan (see the Post Scan Operations section there).
Some of the actions can also be set up to be performed automatically after scanning (see Automatic Actions).
To run the reflect scanning of the crown, perform the following steps:
Start Helium Polish Oxygen and open the project.
|
The stone is lighted from below at different angles so as to observe a reflection from each particular facet in turn. The photos of the crown reflect scan are saved and can be reviewed later.
Crown reflect scanner is capable of highlighting the facets with slope < 40°. |
Some post-scan operations may be initiated via the Scan & Build section. Switch between Basic and Advanced set of operations using the button at the bottom of the section. The Crown Reflect scan shares available operations with the Shadow Scan (see the Post Scan Operations section there).
