Precise observations through surgical loupes and other optics during ophthalmic practice depend on bright, clear, and reliable illumination to ensure ease of operation and quality patient care. With more than half a century manufacturing the finest medical optics, Neitz understands this need. That is why they produce the award-winning NSI-X 80, an LED illuminator for surgical loupes featuring industry-leading brightness and exceptional battery life.
The NTZ-NSI-X 80 illumination combines power and precision: a uniform LED light beam, free of shadows and hot spots, that illuminates the surgical field with true color fidelity. It can be mounted directly onto the loupe frame for a compact and balanced setup, or onto a headband, which distributes the weight across the head and provides greater comfort during extended procedures. Choose the configuration that best suits your technique.
The NTZ-Headlight NSI-X-80 offers the brightest light on the market. This innovative illumination is based on an 80 mm beam diameter, providing professionals with a wide and perfectly illuminated working field during every procedure.

The long battery life, exceptional brightness, and comfortable design of the Neitz NTZ-Headlight NSI-X 80 illuminator make it the perfect complement for Neitz BL surgical loupes and a powerful tool for any clinic.

The NTZ-Headlight NSI-X 80 operates on an integrated rechargeable NiMH battery capable of sustaining the highest illumination level for 3.5 hours. At the intermediate illumination level, the NTZ-Headlight NSI-X 80 can deliver a remarkable 7.5 hours of light, sufficient even for the longest days in the clinic. Should the battery become depleted, its rapid-charging technology allows for a full recharge in as little as 2.5 hours.


The small and lightweight form of the battery and the long reach of the cable connecting it to the LED body allow the NTZ-Headlight NSI-X 80 to rest comfortably in a coat pocket or clipped to a belt.


The NTZ-Headlight NSI-X 80 Illuminator can be turned on/off remotely using the Remote Switch when connected to the Remote Jack (REMOTE) of the Battery Pack, providing the physician with maximum convenience. The Remote Switch operates by pressing the On/Off Switch when the Light Adjustment Knob has been set to level 1, 2, or 3. Each time the Remote Switch is pressed, the Illuminator toggles between on and off. After connecting the Remote Switch, hang it at a point where it can be easily operated using the Hook of Remote Switch.

The NTZ-Headlight NSI-X 80 Illuminator has been designed for use with the Neitz Unbreakable Frame and the Neitz Binocular Loupe.

This level of brightness facilitates ophthalmic examinations with the Neitz surgical loupe line and provides crystal-clear clarity to videos and images captured with the SC-I surgical camera system. This is just one of the reasons why the NSI-X received the Good Design Award 2014.
