HSI-K02 and HSI-K03 Microprojection Modules – Specifications

The HSI-K02 and the HSI-K03 microprojection module is a compact opto-mechanical assembly that combines LCoS microdisplays and LED illumination. The Micro Projection Engine becomes a small projector when combined with an ocular lens for Near-to-Eye applications or combined with a projection lens for a front projector application.
Besides volume distibution, HOLOEYE Systems offers the HSI-K02 Plug and Play Development Kit for prototype systems. With this ready-to-use LCoS™ microdisplay development kit you can quickly and cost-effectively demonstrate prototype performance. The HSI-K02 development kit was designed to be a flexible engineering tool and to speed up R&D; time to market.

HSI-K02and HSI-K03 Key Features and Benefits

  • Over 4,000 fL maximum brightness:
    Extraordinary brightness and clarity greatly enhance image quality.
  • Applicable to field-of-view optics:
    The design enables a variety of Field-ofView products.
  • >93% microdisplay fill factor:
    Delivers smooth, high-quality images without pixelation or the “screen door” effect.
  • Lightweight:
    Just 23 grams, the display with illumination module is ideally suited for applications that require a compact, mobile design.
  • Complete drive-electronics + module solutions:
    The device can easily be adapted to meet a range of reference and custom design requirements.
