Refractive index of the polymer. The required wavelength must be reflected back. non linear optical polymer type of material may be effective.

Would you explain which optical properties are important in light aberration through optical limiter?

Thanks in advance

Dr A. Kumar

Wavelength dependence of refractive index of polymer should be responsible for abberation effect.

George A Stanciu

Refractive index of the polymer is the most important parameter.But what you mean by: optical properties?
