Design challenges – our optical system design work

The housing requirements are strict, since the overall system must comply, ergonomically, with human factors. The system was optimized to work both in direct view mode and in digital camera mode.

Working closely with the customer’s engineering team we were able to understand the requirements and translate them into optical performances specifications.


  • The resolution improved by an order of magnitude.
  • The magnification increased by 44%.
  • Intubation procedure became easier.
