Fibre used in optics is altered (5)

Ross

I believe the answer is:

sisal

'fibre' is the definition.
(I know that sisal is a type of plant fiber)

'in optics is altered' is the wordplay.
'in' indicates a hidden word.
'SISAL' is hidden within 'optics is altered'.

'used' is the link.

(Other definitions for sisal that I've seen before include "Sails (anag) - fibre" , "Plant yielding rope fibre" , "Agave fibre found in bad sails" , "material for painter, say?" , "constituent of rope" .)
