PROPixx Lite

New display toolbox optimized for the needs of vision researchers

The PROPixx Lite is a unique DLP LED projector which has been designed to be the most flexible display possible for vision research. The PROPixx Lite features a native resolution of 1920 x 1080, and can be driven with refresh rates up to 500Hz with deterministic timing.

The PROPixx Lite uses high brightness LEDs as a light source, giving a larger color gamut and much longer lifetime than halogen light sources (60,000 vs 2,000 hrs). Our LEDs also support high bit depth, and high frequency full color stimulation, which would not be possible with a color-wheel/halogen architecture. For stereo vision applications, our high speed ferro-electric circular polarizer can project stereoscopic stimuli for passive polarizing glasses at up to 400Hz.

In addition the PROPixx Lite includes peripherals which often need to be synchronized to video during an experiment, including a button box port for precise reaction-time measurement, and triggers for electrophysiology equipment. Because we implemented the video controller and peripheral control on the same circuit board, you can now successfully synchronize all of your subject I/O to video refresh with microsecond precision.

The PROPixx Lite is available with multiple projection lens options including short-throw lenses for CRT-replacement applications, and long-throw lenses for MRI/MEG applications.

Features:

• Up to 500 Hz refresh rate
• Up to 12 bits RGB intensity
• Up to 1920 x 1080 display resolution

• Short and long throw lenses available
• Passive 3D with 400Hz ferro-electric circular polarizer
• Electrophysiology trigger outputs
• Response box interface
• All digital inputs/outputs feature microsecond synchronization to video refresh
• Upgradable to full featured PROPixx
