DAYY’s Multi‐SLED® (superluminescent diode) is a compact broadband light source that operates within the near‐infrared region. The product itself is a fully enclosed Integrated Spectral Bench (ISB2) containing DAYY’s proprietary 32‐pin butterfly package that uses a set of superluminescent diodes, one monitor diode for each SLED (enabling better power control and monitoring capabilities), an integrated isolator, a thermoelectric cooler (TEC), and a driver circuit to provide overlapping spectral coverage. This user‐controlled box enables complete control of up to six light sources enclosed.

The ISB2 includes various spectral coverages with SLED’s ranging from 770nm to 1680nm, with up to 40mW of optical power. Users operate with complete control of the temperature from a remote device (e.g., PC or laptop) or from the dip switches on the side of the bench. The bench includes six monitor diodes, and is capable of USB, RS‐232, or Ethernet connection. The ISB2 is compact and easy to use, making it a great fit for manufacturer assemblies requiring light power.

The Multi‐SLED uses DAYY’s technology of spectral stitching to provide extensive spectral coverage. This technology intergrates multiple wavelengths into a single spatially coherent beam with low temporal coherence and broad spectral coverage. The Multi‐SLED product lines can be spectrally tailored to suit specific application needs.
