INSPECTION OF INTEGRATED IR COMPONENTS
INSPECTION OF INTEGRATED IR COMPONENTS
The document discusses the inspection of integrated infrared (IR) components using NLIR's MIDWAVE Spectrometer and PRECISION Interface. It highlights the advantages of these tools in providing fast and sensitive spectroscopy for IR devices such as coatings and filters.
The MIDWAVE Spectrometer is designed to inspect IR devices efficiently, offering a bandwidth of 2.0 – 5.0 µm and a resolution of 6 cm⁻¹. It provides full-spectrum readout at a rate of 400 Hz, significantly faster than conventional FTIR spectrometers. The spectrometer's standard fiber coupling facilitates easy light transmission to and from samples.
The PRECISION Interface addresses the challenge of transmitting maximum sample information to the spectrometer. It connects seamlessly with the FIBER Light Source and MIDWAVE Spectrometer using standard infrared fibers. The setup is suitable for examining small areas, with a measurement area less than 400 µm in diameter, ideal for integrated devices requiring high precision.
The effectiveness of the fiber reflection probe is demonstrated through the measurement of an integrated bandpass filter. A gold mirror was used as a reference, revealing a dip in reflectance at 4 - 7 µm, indicating the center of the bandpass filter. The probe provides high-quality spectra from small samples quickly, with a total measurement time of 100 ms.
NLIR's PRECISION Interface and MIDWAVE Spectrometer offer a reliable and efficient solution for inspecting small samples on integrated devices, providing accurate measurements in minimal time without the need for data smoothing or post-processing.

Inspection of Integrated IR Components FAST AND SENSITIVE SPECTROSCOPY Our MIDWAVE Spectrometer is extremely useful for inspecting the performance of integrated IR devices, for example IR coating or filters. Unlike conventional FTIR spectrometers that can take too long to provide accurate results and are not easily fiber coupled, our fast and sensitive MIDWAVE Spectrometer can deliver useful data in just milliseconds; the standard fiber coupling makes it easy to bring light to and from the sample. 2.0 – 5.0 µm and a resolution of 6 cm⁻¹, our spectrometer boasts a maximum fullspectrum readout...
