Technical Issues - Ocean Optics Support

FTG Software supports Ocean Optics spectrometers via 32-bit OmniDriver. OceanView is not required. The FilmStar (Scantraq) setup file installs Ocean2.exe for OmniDriver 2.46 (Mar 2017). When running the setup, select Redistributable version and default WinUSB drivers.

If you do not wish to update Ocean1.exe or your current Ocean2.exe, select Complete FilmStar installation instead of Update current FilmStar programs and DO NOT CHECK Ocean Optics Server.


The FTG Ocean Optics Server (FTG OOS) is an ActiveX EXE which provides an interface to OmniDriver. The advantage of this approach is that the server can be run standalone for testing and then run invisibly from FilmStar. Since the FTG OOS processes data (converts to %R or %T) it can be used in DESIGN as well as MEASURE. An FTG HASP enabled for MEASURE or Scantraq is required.

When installing FilmStar (Setup32.exe), select PE Lambda 2-950 (Mpe983.exe) and Ocean Optics Server in the Select Components dialog. Other versions of MEASURE (Scantraq) do not support ActiveX servers.

This installs Ocean2.exe as well as corresponding FilmStar BASIC macros. It also installs Scan Method OOI2 Trns.scw which references the BASIC macros.


Testing OOI Server in standalone mode

By 'process data' we mean that the server manipulates Dark, Reference and Sample scans. A Standard File provides means to include known reflectance values corresponding to the Reference scan. The Standard is what the Reference is known to be.

This is different from a 'raw data' server where the processing takes place in the host application. BASIC macros for processed data are simpler. As shown below, the FTG OOS includes a Scan Method dialog, but in actual operation, settings are specified in FilmStar BASIC code.

To help determine values for an FTG OOI Scan Method, run SpectraSuite to quickly determine Integration Time and other factors.

In DESIGN the Macro Commands dialog assigns scan functions to macro buttons:

You could use the same Macro Commands in MEASURE, but it is better to assign macros in the Scan Method 1B dialog shown below. Dark and Reference scans are triggered by Setup menu commands, while the Sample scan is assigned to the Scan button. The Scan Method stores the required macros.

Ultimately, Ocean Optics scanning appears seamlessly built into DESIGN or MEASURE:

If Ocean2.exe standalone mode works but MEASURE does not, it is probable that ActiveX references have been changed or lost. In that case merely re-establish the reference in each BASIC program listed in the Scan Method 1B dialog, i.e. BASIC programs assigned to menu commands.
