The NEW light source reproduces clean illumination in Halogen bulb color and eliminates the filament shadow. LED light source provides steady illumination for 50,000 hours, free exchange the light bulb.The combination of the LED and the powerful re-chargeable battery allows 5 times longer operation and 10 hours continuous lighting.
This high degree of visual clarity is due, in part, to the superb illumination of the NTZ-BIO-IO-a LED. The illumination diameter is adjustable and can be set to 19 mm, 50 mm, or 80 mm, depending on the application. The 3W LED has a color temperature of 3200K, matching that of the halogen bulbs in the average indirect ophthalmoscope.
The color temperature of the LED of Neitz IO-a LED is 3200 K , which is same color temperature to the halogen bulb used in the typical binocular indirect ophthalmoscope. The colors observed in ophthalmoscopy are red of blood vessel, orange of retina and yellow of optic disc.
Halogen Bulb Illumination
NEITZ LED Illumination
Commom White Color LED
Differently from common white color LED used in the binocular indirect ophthalmoscopes of other manufacturers, our halogen bulb color LED reproduces these colors with high color rendering properties as shown in the chart on the left. It supports operator to obtain the maximized information from the fundus observation for more precise diagnosis.
It enables to observe fundus under the same condition of illumination compatible to the halogen bulb illumination of familiar.
For specific applications, UV, blue, and red-free filters are included. The low power draw of the LED and the high-capacity rechargeable battery pack lets it run 5 times longer than the competitors, providing 10 hours of continuous lighting and 5 hours at max brightness. This, alongside the device's flawless optics, means clear stereoscopy can be achieved through even a narrow pupil diameter of 2 mm.
Because of the quality of the NTZ-BIO-IO-a-LED, it often accompanies its owner for a life time. From school and training, through to a practice or hospital environment. With the most complete and flexible power source offering, your binocular will adapt to any environment. If your needs or requirements change, the power sources are modular and completely interchangeable. The battery comes with a clip that allows it to be mounted on a belt or headset.
Fundus image can be observed stereoscopically even through a small pupil of 2 mm diameter. Observation angle can be continuously changed. Smooth single hand adjustment of mirrors allows the observation easily in any desired angle. The halogen light provides suitable illumination for general observation.
The unique optical system in the NTZ-BIO-IO-a LED makes it possible to change the approach angle to the pupil to either vertical or horizontal positions allowing users to observe the periphery of the fundus from any angle. Furthermore, the illumination light mirror and observation mirrors can all easily be adjusted with a single hand. This flexible system can adapt to the face of most users using an adjustable pupillary distance from 54 mm to 74 mm.
Freedom in choice of the approach angle to the pupil.
The system allows to adjust the position of the mirrors into vertical or horizontal positions corresponding to the patient pupil. It enables the operator to observe the periphery of the patient fundus from any angle.
The NTZ-BIO-IO-a LED has as an optional accessory a teaching mirror (sold separately) for observers and students to see from the user's perspective, making it ideal for in-person education. It also comes with a carrying case and a comfortable head strap. These features and the guarantee of quality that comes with all the ophthalmic products by Neitz ensure it can meet the needs of any ophthalmological clinic.
