The Light Sensor Cedrus is a small and accurate photocell, measuring a mere 8mm (W) by 20mm (L) including the wire’s strain relief (8 by 14mm without it). It comes in in two colors: black and white. Notches are molded in on three sides to allow for easy positioning on the screen.
Our photo cell sensor is a light-to-voltage optical sensors, each combining a photodiode and
a transimpedance amplifier (feedback resistor = 16 MW, 8 MW, and 2.8 MW respectively) on a single monolithic
IC. Output voltage is directly proportional to the light intensity (irradiance) on the photodiode. These devices
have improved amplifier offset-voltage stability and low power consumption and are supplied in a 3-lead clear
plastic sidelooker package with an integral lens. When supplied in the lead (Pb) free package, the device is
RoHS compliant. Comes with 1.5m cable and AUX connector, to be used with the ActiveTwo EEG System (requires ERGO input).
LED photic stimulator with articulating arm, control software, cabling.
Ideal for photic activation during EEG studies, this LED photic stimulator combines the brightness of a Xenon flash with the utility and ease of use of an LED device. The device has an equivalent lamp shape and brightness to the Grass PS33 whilst being smaller, lighter and more energy efficient by utilizing bright light LED technology. The disadvantages of Xenon tube lamps are well known. They are heavy mains powered devices that are generally very expensive, whilst posing a potential safety hazard to the patient and operator.
Package includes: Photic LED Flash, USB connection cable, cable clamp, software to run the photic, color filter pack, trigger cable.
