Open OPD File
OPD files have two different applications, namely:
OmniPage
In this use case, an OPD extension file is a document created with OmniPage scanning software.
OmniPage is a character recognition software developed by Kofax Incorporated, and it was one of the first OCR software packages available for PCs.
The OPD file can contain images, text, and page layout information.
The OPD is saved in a proprietary format that can only be opened with OmniPage or OmniPage Professional software.
OmniPage was initially developed by ScanSoft, and is now owned by Kofax Inc.
Durango
In this application, the OPD file acts as a data file created by Durango, a program used for the analysis of data measured by interferometers.
Durango software is used for data acquisition, analysis, evaluation, exchange, import / export, and simulation.
Durango uses published algorithms and gives you full access to raw measurement data and intermediate results.
The OPD file stores Optical Path Difference type visualizations, hence its acronyms, as well as supporting data sets, and therefore, it is used for the metrology of optical surface figures.
