• Competitive Advantages

      Superior lm/W Ratio: Collects All the Light
      - Collects the light emitted from the LED die to the whole hemisphere (+/-90 degrees)
      - Works equally well with both encapsulated LED dies (Luxeon, ZLED) and non-encapsulated LED dies (OSTAR, Luminus Devices)

      Ultra Small Size: All-in-One Illuminator
      - Integrates light collection, beam forming and homogenization functions into one component
      - Minimizes the whole projector engine size by allowing LED die to be placed very close to or at the illumination pupil position

      Preserved Etendue
      - The etendue of the output beam is equal to the etendue of the source
      - The output beam is spatially and angularly solid without etendue increasing holes

      High Collection and Guiding Efficiency
      - Provides up to 80% efficiency from the LED die to the microdisplay imager

      Minimized Engine Losses
      - Spatially the output of the PhotonVacuum component is circular with uniform irradiance, which provides optimum match to the projection lens pupil
      - Angularly the output of the PhotonVacuum component is rectangular, which provides optimum match to the microdisplay shape

      Good Uniformity
      - Provides uniformity better than 85% inside the illuminated rectangular
