Details
High-temperature mid-infrared (MIR) light sources are relatively cheap and require only simple electronics; they emit light of high power and are stable and robust. However, due to the nature of the warm emitter, the light is incoherent and emitted in all directions, which makes it difficult to guide and focus the light onto a sample with high intensity.
NLIR’s FIBER Light Source makes it easy to bring MIR light to a sample either by positioning the fiber tip close to the sample or by using commercially available fiber-probes.
The light source is plug-and-play, turns on in a few seconds, and is actively temperature stabilized, and no parts are too warm to be touched.

Experience real-time measurements
FIBER Light Source powers effortless measurements of various samples and applications. Explore our measurement examples below.
Optical Coating Transmission Measurements
In this video, we demonstrate how NLIR’s MIDWAVE Spectrometer, combined with FIBER Light Source, can measure transmission spectra of optical filters in real time. With an exposure time of just 2 ms, the spectrometer captures data from every filter on the rotating wheel during each full rotation.
Multi-Component Gas Sensing
The video demonstrates multi-compenet gas measurement in real time. NLIR’s FIBER Light Source delivers light through a fiber to a simple gas cell, while another fiber guides the transmitted light to NLIR’s MIDWAVE Spectrometer. The spectrometer captures spectra every 20 milliseconds, clearly showing the transmission features on screen.
This setup can be installed in industrial environments to provide real-time data on the composition of gases inside pipes or chambers.
