No matter how well-crafted the internal optics of a surgical loupe may be, it cannot produce clear, sharp images without a quality light source. Neitz has channeled its 50 years of experience in medical optics into the NTZ-Headlight NSI-III to create a versatile, high-power illuminator for ophthalmic examinations or surgical procedures with the BL loupe line. The NTZ-Headlight NSI-III achieves the perfect combination of adaptability and affordability without compromising on quality.

The NTZ-NSI-III lighting combines power and precision: a uniform LED 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, balanced setup, or onto a headband, which distributes weight across the head and provides greater comfort during extended procedures. Choose the configuration that best suits your technique.
The 3W LED light source of the NTZ-Headlight NSI-III provides 3 different cold white light intensities, ranging from 13,000 Lux to 40,000 Lux at a distance of 9.84 in.
The NTZ-Headlight NSI-III operates on the included NiMH AA “Eneloop” rechargeable batteries and can deliver the highest illumination level for up to 4 hours. The NSI-III can operate for 7 hours at medium intensity and up to 17 hours at low illumination — more than sufficient to cover even the longest clinic days. The NTZ-Headlight NSI-III comes packaged with a battery charger capable of fully recharging the batteries in as little as 4 hours. This device can also be used with standard replaceable AA batteries, providing the versatility needed to remain operational during travel and power outages in emergency situations.
The battery pack case fits easily in most jacket pockets, and the long cable connecting it to the LED illuminator makes it convenient to use and carry. This design avoids concentrating all the weight on the nose, making it comfortable for any duration of use.
The NTZ-Headlight NSI-III front headlight provides users with the necessary illumination for direct visualization or for video/image capture through the SC-I surgical camera, compatible with Neitz surgical loupes.
The NTZ-Headlight NSI-III is compatible with both the Neo Frame and the standard headband of the BL line of surgical loupes, offering the professional the flexibility to adapt it to the mounting system that best suits their working style.
