CU-35-1600 1600nm Led Emitter, 1600nm SWIR illumination in a compact SMD3535 high-power package. The CU-35-1600 is a 3W-class infrared LED designed for sensing applications that benefit from SWIR spectral contrast—particularly where moisture and chemical composition influence reflectance.
This emitter is built with a ceramic substrate, silicone lens, and 99.99% gold wire bonding (1.2mil), and is listed as CE and RoHS compliant on the manufacturer page.
Key features
- Model: CU-35-1600
- Package: SMD3535, ceramic substrate, silicone lens
- Chip note: Epileds/Epistar, 1pc × 42mil chip (per manufacturer listing)
- Beam options: 30°, 60°, 90°, 120° and flat lens (no dome) options available
- Compliance: CE / RoHS (per manufacturer listing)
Typical SWIR applications (1600nm)
- Gas detection & analysis: absorption/reflectance systems using SWIR detectors.
- Moisture content measurement: inline or benchtop sensing where water content affects SWIR response.
- Industrial process monitoring: stability trending and closed-loop process control.
- Medical diagnostic equipment: SWIR illumination in instrumentation (integration dependent).
- Alcohol concentration testing: analytical setups using SWIR channels.
- Petroleum quality control / chemical process control: SWIR analytical instrumentation.
- Scientific research instruments: lab SWIR illumination modules.
Integration note: 1600nm is in the SWIR band; systems typically use InGaAs photodiodes/cameras rather than silicon sensors.
