The ColorDome full-field Desktop Ganzfeld is an industry-leading stimulator designed to provide capabilities for the most advanced ERG testing. The Colordome features full color capability made possible by an advanced LED and Xenon system capable of producing flashes at 10 times the industry standard. No other Ganzfeld currently available comes anywhere close to providing the range, flexibility, compactness, and ease of use that the ColorDome brings to the market.
ColorDome Detailed Specifications
Flash Specifications:
LED Flash Specifications:
Any color flash (from red, green, blue and amber LEDs
UV LEDs also available)
LED sets produce 9 order-of- magnitude luminance
using 3 LED ranges
Flash duration 4ms or less using 16ns PWM control
Proprietary CIE compensation yields ultra-stable
luminance and color output
Maximum white flash > 30cd.s/m2, 10x ISCEV standard flash
On/Off flashes of any duration, waveforms including
sine and exponential, arbitrary wavetable
Calibrated in photopic and scotopic units and Trolands
User defined color/luminance stimuli
Xenon Flash Specifications:
Xenon flash calibrated from 0.001cd.s/m2 to 3000cd.s/m2
Flash duration 5us to 2ms automatically adjusted
Auto calibration system monitors each flash and adjusts flash
duration in real-time to produce accurate output
Integral filter holder for adding customer filters
if required
Max white flash > 3000 cd.s/m2, 1000x ISCEV standard flash
Calibrated in photopic and scotopic units and Trolands
Capable of double flashes including
“double bright flash” protocol
User defined Flash Sequence
Overall Flash Specifications:
Flash luminance range from 10-9 to 3000cd.s/m2
Anywhere within this > trillion to one range luminance can be changed
with no less than 1% resolution
Background Specifications
Any color background (from red, green, blue and amber LEDs)
Low dim, dim, and bright LED sets produce 6 order-of-magnitude
luminance range
Calibrated luminance output in cd/m2
Calibrated in Scotopic and Photopic units
Colors selectable using standard CIE coordinates or color picker
Dual ColorDome capability allows simultaneous,
independent control of two ColorDomes.
EOG Specifications
9 red EOG LEDs spanning 60 degrees as well as the standard 30 degrees
Adjustable intensity
Can be cycled in square wave mode (end LEDs light alternately) or
sinusoidal mode (LEDs change from end to end in sinusoidal manner)
