WebOct 18, 2024 · choosing refractive targets. It would seem logical that emmetropia is the ideal refractive state of the eye. It puts far away objects in perfect focus. Then the natural … WebIn this IXC-FBG-PS design, a Phase Shift (PS) is introduced within the middle of the stop band. This PS will lead to a sharp resonance peak visible in the transmission spectrum response and features less than 1 dB of insertion loss. Our narrow bandwidth transmission filter IXC-FBG-PS can be used as a narrow band transmission filter in telecom ...
