What is ZBLAN fiber?

ZBLAN fibers are optical fibers made from fluorozirconate (ZrF4) glass, known for their high transparency in UV, visible, and mid-infrared spectra, up to 4.5 µm.

What are the advantages of ZBLAN fibers?

ZBLAN fibers offer low transmission loss, with typical losses less than 20 dB/km at 2.5 µm, making them ideal for applications requiring efficient transmission in the mid-infrared range. ZBLAN fiber are more transparent than silica fiber above 2µm. Unlike most of other mid-IR fibers, ZBLAN exhibit limited Fresnel losses (<4% per face)

What are the operating wavelengths for ZBLAN fibers?

ZBLAN fibers can operate effectively in a wavelength range from 0.32 to 4.3 µm with losses less than 1 dB/m.

. What are the typical applications of ZBLAN fibers?

ZBLAN fibers are used in applications requiring efficient transmission in the mid-infrared range, such as sensors, lasers, optical communication systems and gas sensing
