Try this :

ffmpeg -pixel_format gray10le -s 1600x1300 -r 30 -i 
CapturedImage-%03d.raw -c:v rawvideo -pix_fmt yuv420p -f rawvideo output.raw

Alternatively you can put the raw video stream in a container such as MKV:

ffmpeg -pixel_format gray10le -s 1600x1300 -r 30 -i 
CapturedImage-%03d.raw -c:v rawvideo -pix_fmt yuv420p output.mkv

In either case I'm not sure it will easy to read the output file with 
classical players.
