Image stream .raw structure

We are working with Sekonix cameras.
For testing purposes and calibration we are saving the image stream with OpenCV in .raw format.
We would like to know the data structure or paket structure of the .raw format.
Do we have to contact Sekonix or does someone already have this information?
Thanks for your answers.

Dear randtie,

Regarding raw file format, could you please refer to below links for your topic? Thanks.
