In the model builder we have inbuilt iteration functionality where we can call the rasters in the workspace.

Thanks, but I don't know how to add the formula.
Because for example formula is NIR -R
So, in raster calculator which NIR and R need to choose because it is many images?
I am so sorry if I am not understand. I still stuck in this.
The band (as images specified by you) specification like bandwidth depends upon sensor. What is your data source? For example like landsat, liss,spot etc...
this might help you;
my sensor is MCA 6 with 6 bands
So if in one folder which data will be chosen since the data in one group.
This is the example for one image, I am successfully did:
But the problem now how to do the same using iterate Rasters?
Step one: Make a model
Step two: Search for "Raster Calculator" in the search window (usually on the left side of the ArcMap Window)
Step three: drag the tool into the model builder box
Step four: double-click the tool and input your equations
Bonus: Use the Iterate function to loop through multiple rasters
