ILF is composed of fiber-optic collimators with our optical thin film filters inserted in between. Center wavelength is fixed at an arbitrary wavelength.
Optical fiber codes are collimated and fixed by welding. This device has excellent reliability andminimal optical axis misalignment.

Product Features

■ For trial fabrication and development of optical communication systems

Just connecting to the other optical components, it performs filtering function.

■ Wavelength selection of WDM systems
ILF with BPF spectrum characteristics easily extracts single wavelength from WDM system.

■Noise cutting (Supplession of unnecessary light)
This device have only necessary light pass and cut noises, by using BPF.
