PixClear® Optical Sensors

That’s Where PixClear® Comes In

PixClear high refractive index (HRI) nanocrystals dramatically improve optical and mechanical properties and performance in optical sensors and components. Applications include:

Wafer-Level Optics
CMOS Image Sensors
3D Sensors
Micro Lens Arrays
Diffractive Optical Elements
Gradient Index Optics (Visible or Short-Wave Infrared Wavelengths)

Made by our patented PixClearProcess®, our HRI nanocrystals are optimized for compatibility with various monomers and resins. When combined, the nanocomposite’s refractive index can be tuned from 1.65 to 1.9+ – without negatively impacting haze values. These materials can be incorporated into both films and optical structures with a wide range of thicknesses, depending on customers’ requirements.
