Short-wave infrared illumination for material penetration and absorption contrast
The SWIR series provides seven wavelengths from 1050 to 1650 nm and is intended for SWIR cameras. Different material absorption, penetration and reflectivity can reveal internal or hidden features that appear differently under NIR.
- Wavelengths
- 1050–1650 nm
- Seven standard points
- Forms
- Ring / spot / line / bar / backlight
- Nine listed models
- Supply
- 24 V or 700 mA
- Model dependent
- Power
- 1.5–108 W
- Model dependent
- Camera
- SWIR-sensitive
- Required
Apple spoilage
Use SWIR absorption contrast to reveal internal damaged regions.
Photovoltaic circuits
Improve circuit-mark contrast at a selected SWIR wavelength.
Wafer holes
Use penetration differences to inspect hidden hole structure.
Food and packaging
Select wavelength for content or fill-level contrast.

Choose wavelength and illumination form from the material response
Nine source rows span ring, spot, line, bar and backlight geometries. Their dimensions, current/voltage and power remain tied to the individual row.
- 1
Compare wavelengths
Test the target at relevant SWIR absorption bands.
- 2
Choose illumination geometry
Select ring, spot, line, bar or backlight based on the feature.
- 3
Match camera sensitivity
Confirm detector and lens transmission at the chosen band.
- 4
Use the exact electrical row
Do not transfer voltage, current or power between forms.

Use the drawing and controller associated with the chosen light form
The source combines nine mechanically different SWIR products. The complete drawing set is therefore retained as one multi-form engineering reference.
- 01
Choose the geometry before allocating mounting space.
- 02
Use the selected drawing number and exact model envelope.
- 03
Match analog, digital, constant-current or high-power control as listed.
- 04
Verify cable flexibility, bend resistance and device temperature.
