Based on a proprietary thin film cavity filter technology, Agiltron offers PM Fiber Optic Tuneable Filter with central wavelengths ranging from 450 nm to 2000 nm. It is tuneable continuously over a wide spectral range up to 80nm. Agiltron further offers high optical power handling up to 10 W(CW) while maintaining the transmission spectral shape polarisation-insensitive over the whole tuning range. Agiltron’s unique high reliability and low insertion loss design presents a most cost-effective solution for OEM applications from fibre optic networks to fibre sensing interrogation.
