Natus Photic Stimulator Xltek Model 10440 10440D3400

The photic stimulator is used by trained medical staff in a medical environment to apply photic flashes tothe patient during neurophysiology studies such as EEG, where it is used as an activation to test photo-sensibility related to epilepsy. Trigger pulses applied to the input of the photic stimulator generate photicflashes at specific frequencies, typically in the range of 0.5Hz to 60Hz. The photic stimulator is intendedfor use on mobile or fixed systems, and with patients of all ages. The Photic Stimulator can also be usedalong with Evoked Potential devices for stimulating Visual Evoked Potentials.

Tested with Xltek Model XLPS-1 Photic Stimulator on hand, appears to be working, you can inquire about a particular detail or possibly testing before purchasing.
