NIT and INSP collaboration on quantum dot SWIR imager

A video on the different stages in the development of sensors for infrared cameras from Institut des NanoSciences de Paris (INSP):


A press release from November 2023 related to this technology:

NIT and INSP will exhibit the world’s first HgTe CQD SWIR camera during the Forum Innovation Defense held in Paris on 23-28 November.

NIT (New Imaging Technologies) and INSP (Institute of Nanosciences of Paris) are proud to announce the debut of the world’s first Short-Wave Infrared (SWIR) camera featuring an innovative HgTe (Mercury Telluride) Quantum Dot focal plane array sensor. This groundbreaking technological achievement will be showcased during the Forum Innovation Defense, taking place in Paris from November 23 to November 28, 2023.

The collaboration between NIT and INSP has resulted in a pioneering SWIR infrared camera, utilizing the advanced HgTe quantum dot sensor technology, which promises unprecedented capabilities in defense and security applications.

Selected by the French Ministry of Defense, NIT, and INSP will present the culmination of years of dedicated research and development efforts in this revolutionary camera. The development of the CQD (Colloidal Quantum Dot) sensor was made possible through funding provided by the French Defense Procurement Agency (DGA) and the National Research Agency, part of a rigorous three-year R&D program.


  1. What are the differences between this CQD and all other CQD announced on this forum please?

  2. sad you not gived info why this type of QD important comparison existed. "world’s first HgTe CQD".
    home work for readers

  3. This is a QD made of HgTe nanocrystal which is unique compared to QD made of PbS or PbSe. It provides advantages such as response time or resistance to humidity.
