Optical Measurement Data:
Other .oma files come from optical marking applications. They store measurement details from instruments used in optical data capture. Devices from companies like Nidek produce these files.

CNC and Robot Program Files:
A few .oma files are used in industrial settings. They can include CNC machine tool data or Fanuc robot program instructions and are handled by specialized editors such as OMA Editor.

OMA file extension format:

The file format determines how the data is stored in the file. Often, the file format can be deduced from the file extension or the initial bytes (called the signature).
