Alongside other offerings from the BL series, it presents two customizable frame options designed to cater to your specific requirements. Among these, the NEO frame stands out as an exceptional choice. Weighing a mere 71 grams , it boasts flexibility, lightness, and a range of color options to add a personal touch to your practice. The NEO frame intelligently distributes the device's weight across three key points: the forehead, nose, and strap, ensuring a comfortable fit even during extended periods of use. Furthermore, the nose pad is specifically designed to alleviate the burden on the nose, and the device features a convenient function that allows it to effortlessly return to its original position, even when flipped up. With the NEO frame, healthcare professionals can confidently carry out their work, knowing they have a comfortable and functional tool at their disposal.

    Excellent fit with moderate "flexibility"


    During procedures, the NTZ-BLS-3 surgical lopue offers a headband option that ensures secure placement on the user's head. The headband is attached with straps that go around and over the head, preventing the device from shifting. Moreover, the lens framework can be adjusted to tilt downward, enabling users to find a comfortable position without excessive head or neck bending. By choosing the headband option, clinicians can enjoy a lightweight and soft fit, allowing them to work comfortably for extended periods. The headband provides stability throughout the entire head, making it an ideal choice for individuals seeking a secure and comfortable method of using the NTZ-BLS-3 surgical loupe during procedures.

The easily adjustable working distance allows users to focus on different mouth areas without having to move. The limited range of the working distance means you will never find yourself out of focus when you need it most. In addition, each lens is independently adjustable, making the NTZ-BLS-3 surgical loupe accessible to people with different types of eyes and eye conditions.


    This truly ergonomic loupe provides you with a neck tilt angel of less than 20 degrees to avoid paint at work. In addition, the ability to adjust magnification and field of view reduces unnecessary leaning, eliminating undue strain on your shoulders, back, and neck.


    The NTZ-BLS-3 surgical loupe is compatible with a range of illuminators, including the Neitz NSI-X, known for its exceptional brightness, and the NSI-III, a lightweight and versatile option that operates on rechargeable batteries or disposable AAs. By attaching either of these illuminators to the device, you can maintain hands-free operation while ensuring precise illumination exactly where you need it – directly on your focal point.
