• Leds for gaze and eye tracking.
• Multi-chip leds for phone flashlights – for example the CW2 FKAP81.Z1* which is a 125 lux 5x5mm device with two die, one at 6,000K and one at 2,250K, each with their own separate Freznel lens moulded into the package for variable colour-temperature photographic illumination (see photo).
• Photodiodes for bio-monitoring in wearables like fitness trackers.
• Infra-red spectroscopy for phones to analyse food or human vital signs. Here is has the SFH 4735*, a broadband (650-1,050nm) IR led.
