SWIR Illumination Enhances Identification with Modern InGaAs Sensors

Teams modernizing their low-light imaging suites needed a SWIR illuminator that matched the sensitivity of new InGaAs cameras while reducing signature in the visible and near-IR bands. Older illuminators often produced bloom, spectral leakage, or insufficient irradiance at operational ranges. Working with RPMC to refine their illumination and spectral requirements, they selected high-power SWIR multimode diodes, available in free-space and fiber-coupled formats in the LDX-SWIR series, providing compact, spectrally aligned output for long-range contrast and recognition.
