INSPECTION OF INFRARED COATINGS
INSPECTION OF INFRARED COATINGS
The document discusses the characterization of infrared (IR) optical coatings using NLIR's MIDWAVE Spectrometer, which offers fast and sensitive spectroscopy for inspecting the precision and performance of IR coatings on various optical surfaces.
The MIDWAVE Spectrometer features a bandwidth of 2.0 – 5.0 µm and a resolution of 6 cm-1. It provides a maximum full-spectrum readout rate of 400 Hz, allowing for rapid data acquisition in milliseconds, unlike conventional FTIR spectrometers.
To address challenges in light guidance during coating inspection, NLIR has developed two fiber-coupled interfaces: the TRANSMISSION Interface and the PRECISION Interface. These interfaces facilitate accurate measurements in both transmission and reflection modes, with a minimum detectable power of 5 pW/nm, enabling the measurement of dark or low-reflective samples.
The TRANSMISSION Interface was tested by measuring the transmission of three bandpass filters and one neutral density filter. The spectrometer acquired single-shot data with an exposure time of 10 ms, demonstrating its speed and reliability. The raw data, plotted relative to a reference, highlights the spectrometer's capability for fast and reliable coating inspection.
