It is compatible with the following critical platforms:

• Xltek: Trex and Trex HD
• Connex
• EMU Systems: EMU40, EMU40EX, and EMU128
• U32
• Brain Monitor

This makes it an essential component for various neurological testing protocols like EEG, LTM, and PSG.

Yes, the Natus Photic Stimulator provides highly adjustable light intensity control, essential for precise neurological testing and stimulation.

Key features of the intensity control include:

• Control Positions: It features a 12-position control (11 distinct settings plus an ‘Off’ position).
• Intensity Range: Measured at a distance of 30 cm, the output is adjustable, ranging from a minimum of 22,000 lux up to a maximum of 75,000 lux.
• Typical Output: The typical observed intensity is 39,000 lux.

The Natus Photic Stimulator is a Certified Refurbished unit that comes with the essential components needed for immediate operation:

• Photic light on arm: This includes the integrated light source mounted on an adjustable support arm, providing 52 inches (1320.8 mm) of total reach for versatile positioning.
• Power supply: The necessary unit to power the device.

It is important to note that an instrument cart, such as the compatible Cadwell Instrument Cart, is sold separately.

The support arm of the Natus Photic Stimulator is 52 inches (1320.8 mm) in total length, providing flexible positioning during medical procedures.

The Natus Photic Stimulator is an essential accessory used for delivering controlled visual stimulation during various neurological monitoring protocols. It is designed for integration into clinical or laboratory settings utilizing Natus/Xltek monitoring suites.

Key studies and protocols that require the Photic Stimulator include:

• EEG (Electroencephalography): Essential for assessing cortical excitability and inducing photoparoxysmal responses.
• LTM (Long-Term Monitoring): Used for extended patient monitoring where controlled stimulation is necessary.
• PSG (Polysomnography) studies: Used for sleep studies when visual stimulation protocols are applied.

Yes, the Natus Photic Stimulator is designed for high-performance neurological testing. It achieves a maximum flash frequency of 60 Hz, paired with a very precise 1 ms flash duration. This capability ensures effective and accurate controlled visual stimulation protocols.

Yes, the Natus Photic Stimulator is designed with key safety and compliance standards in mind. It meets high requirements for electrical and material safety:

• Protection Against Electric Shock: The device is classified as Class 1, which indicates a high level of protection against electrical hazards.
• Flammability Rating: The unit adheres to the strict UL 94V-0 flammability standards for material components.

The Natus Photic Stimulator requires a precise external trigger signal to synchronize its flashes with compatible Natus/Xltek monitoring systems.

The technical requirements for this input signal are:

• Type: TTL Positive Pulse
• Specifications: 100 µs at 1 mA

This dedicated input ensures accurate timing for procedures like electroencephalography (EEG).

The typical measured light intensity for the Natus Photic Stimulator is 39,000 lux.

This device features a precise 12-position control (11 settings plus 1 Off position) for adjusting intensity.

At the maximum setting (Position 12, measured at a 30 cm distance), the light intensity range is:

• Minimum: 22,000 lux
• Maximum: 75,000 lux

Yes, for safe and effective operation in a clinical environment, the device must be mounted to a stable, compatible structure. Specifically, it is designed for integration with the Cadwell Instrument Cart (Model #MFI-CDW-197224-200), which is available for purchase separately.
