[mems-talk] Refractive Index of Photoresists

[Martyn Gadsdon]

Dear All,

I am interested in finding out what the difference in refractive index is 
between un-exposed (with uv radiation) and exposed photoresist. Particularly 
I am interested in knowing what photoresist (or other substance that can be 
applied by spinning) will give me the most difference in refractive index 
between exposed and unexposed areas.

Many thanks,

Martyn Gadsdon.
