FAQ. Why do you recommend using an FBG with a >0.5 nm FWHM for SmartScan instruments?

The algorithm embedded in the SmartScan needs several laser tuning points to overlap the reflection shape of the FBG. In order to achieve a non-linearity error compatible with the SmartScan Specifications, we recommend to use FBG with an FWHM between 0.5 and 1 nm.

Narrower FBGs can be used, at the expense of reduced linearity.
