Making Light Work

What is Zeroptica Technology?

Zeroptica is a solution based method for fabricating subwavelength structures to achieve functionalities such as antireflection, self- cleaning, anti- fingerprint etc. Using Zeroptica on your existing products will:

  • Eliminate unwanted light reflections using sub-wavelength nanostructures
  • Increase transmission
  • Modify the hydrophobicity of the surface. For example, it can make a surface superhydrophobic
  • Low cost, highly scalable and applicable to both flat and curved surfaces

The challenges

Light is reflected from an optical surface due to difference in refractive index of the materials. Light reflection is why you can’t see the screen of your laptop and mobile phone in sunshine. Eliminating unwanted light from an optical surface has significant advantage in many applications and can improve the efficiency of many devices such as optical lenses, solar cells, night vision goggles, LEDs, medical cameras etc.

The Concept

Zeroptica eliminates light reflections off optical surfaces by nano-structuring using a self-assembled soft polymer mask to form sub-wavelength structures, whereupon etching creates an omnidirectional broadband AR interface. The patent-pending process is low cost, highly scalable, involves no surface coatings, and can be applied to flat and curved surfaces.


Applications range from high-power laser windows and optical lenses to higher efficiency LEDs, OLED, PV and IR cameras.
