Crossword Genius

It provides outstanding images (11)

Ross

I believe the answer is:

stereoscope

I'm a little stuck... Click here to teach me more about this clue!

'it provides outstanding' is the definition.
The definition suggests a singular noun which matches the answer.

'images' is the wordplay.
I cannot really understand how this works, but
'images' could be 'stereos' (stereo is a kind of image) and 'stereos' is located in the answer.
The remaining letters 'cope' is a valid word which might be clued in a way I don't understand.
This may be the basis of the clue (or it may be nonsense).

Can you help me to learn more?

(Other definitions for stereoscope that I've seen before include "Three D viewer" , "Device offering 3-D viewing" , "Three-D viewer" .)

I've seen this clue in The Globe and Mail.
