Product description
The LuxaLight Industrial LED Fixture Polarised cover NIR 860 nm is an industrial NIR luminaire with a measured peak wavelength of 852 nm. It combines an aluminium PCB with SMD LEDs on an integrated aluminium heatsink, sealed by a linearly polarising PMMA cover in an IP64 housing.
The polarising PMMA cover delivers linearly polarised NIR radiation, effectively suppressing specular reflections and stray light. Used in cross-polarisation with a matching polariser on the camera, it produces substantially higher inspection contrast on metals, foils, glossy coatings and transparent substrates than unpolarised NIR sources can achieve. PMMA additionally provides good transmission across the 800–1000 nm range and mechanical protection of the LED layer.
Applications
Glare-suppressed machine vision — Linearly polarised NIR suppresses specular reflections on metals, foils, glass and coated substrates when used in cross-polarisation with a camera-mounted polariser. At 10 cm working distance the fixture delivers 139 W/m² irradiance, sufficient for industrial CMOS cameras at line speeds where unpolarised illumination causes saturation. Applicable to PCB inspection, defect detection on coated surfaces and packaging inspection.
Hyperspectral and spectral imaging — 852 nm is a key band for NIR hyperspectral analysis, including polymer identification in plastic sorting, moisture content determination and food quality inspection. At 5 cm the fixture provides 345.3 W/m² irradiance for clear spectral signals. For wash-down lines in food processing and pharma, a variant with water-cooled stainless steel 316 housing is available within the same platform.
Iris and biometric recognition — The 852 nm band falls within the ISO/IEC 19794-6 window for iris imaging (700–900 nm), where iris pigmentation becomes transparent and stromal microstructure is revealed to the sensor. The polarising cover reduces specular reflections from cornea and eyewear that would otherwise mask iris detail, improving matching reliability in access control and border control applications.
Photobiomodulation research — 852 nm lies within the optical tissue window (approximately 650–950 nm) where haemoglobin and water absorption are low and penetration depths of several centimetres in soft tissue are realistic. At 10 cm the fixture delivers approximately 13.9 mW/cm², allowing a typical research dose of 4 J/cm² to be delivered in around 290 seconds — suitable for PBM protocols on muscle, joint and skin tissue.
Vegetation and crop sensing — Above 750 nm healthy leaf pigmentation reflects strongly, making 852 nm a suitable NIR band for NDVI and vegetation index measurements, plant tissue moisture detection and non-destructive stress monitoring. The stable NIR output serves as reference illumination for reflectometric sensors in growth chambers and phenotyping platforms.
Integration
This fixture is designed as a building block for industrial NIR systems. The modular platform architecture provides different cooling, cover and wavelength variants within a single design; configurations and use cases are detailed in the modular fixture info sheet in the download section.
The 24V CV platform enables fast pulse switching, essential for peak output above nominal power. In pulsed operation, a higher instantaneous irradiance can be achieved than in continuous operation at equal or lower average power — delivering higher efficiency in many applications. Combined with the MaNima Pollux Industry controller, the fixture provides real-time monitoring of current, voltage and temperature, PWM control and pulse control with adjustable pulse times from 2µs to 1000ms. The controller supports Ethernet connectivity for PLC and SCADA integration, UDP, analogue signals, digital contacts and network protocols for seamless connection to existing process controls and machine environments.
