1660nm broadband fiber Bragg grating filter
Idealphotonics introduced coherent excimer writing technology and technically recognized packaging technology to solve the reliability problems of fiber grating products. It also used its excellent holographic phase mask technology XmaskTM and grating writing technology to achieve technical breakthroughs in many products in the field of FBG technology. Products include gain flattening filters (GFF), single-channel and multi-channel dispersion compensators, dispersion slope compensators, pump laser frequency stabilization, gratings for fiber lasers, etc. The company introduced Yokogawa high-precision spectrometers and we have achieved a spectrum for each fiber, so that customers can better understand the performance of the products. Our special wavelength fiber gratings have been effectively verified in some special application fields, providing a large number of reliable special wavelength products for domestic scientific research fields.
