ZEISS VELVET SIM LED VISIR The ideal solution for day/night simulation and stimulated NVG training

ZEISS VELVET SIM LED VISIR is the projector for all conceivable training situations. In addition to day/night simulation, the integrated infrared technology enables simulation of night vision missions through direct stimulation of night vision goggles. The projector's modular design allows the upgrade of new developments.

  • Infrared channel for night vision goggles
  • Native contrast of 2,500,000 : 1
  • Optimal gray gradation
  • 10Bit color depth
  • Integrated 10 bit blending

Night vision mode

A dedicated video signal input can be used to feed the projector with effects such as IR searchlights or IR laser targeting, which cannot be perceived without night vision goggles. Thus, thoroughly realistic training is possible with night vision goggles.

High contrast

Native contrast ratio of 2,500,000 : 1

ZEISS VELVET SIM LED enables projection of a completely black image background without disturbing residual light. With a native contrast of 2.5 million to 1 - the highest on the projector market - ZEISS VELVET SIM LED projectors offer the greatest possible sharpness through clearly defined pixels and optimum image resolution. This allows the system to perfectly replicate reality.

Optimal gray gradation

The gray gradation is optimal over the entire brightness range. From pristine white to the darkest grayscale, colors are reproduced true to life. Thus, the finest differences in brightness become perceptible during night simulation. The glare areas between the projection channels are free of artifacts even in the darkest scenarios. ZEISS VELVET SIM LED thus ensures total immersion in the projection.

Gradient 8 bit
Gradient 10 bit

10Bit color depth

Another special feature is the 10-bit color resolution for each color on the screen. This ensures the best possible transition between channels and prevents artifacts. Four times as many shades of gray are available compared to standard 8-bit video signal processing. Semi-dark scenarios such as dawn and dusk are rendered more realistically, as artifacts are eliminated, especially in color gradients.

Integrated 10bit blending

Regardless of the input signal, the blending in the projector is always calculated in 10bit color depth. This always creates artifact-free blending areas between the projection channels. The channel transitions normally visible in dark images are a thing of the past. The interference-prone construction of mechanical shutters in front of the lens exit becomes superfluous. Nothing stands in the way of total immersion in the simulation.
