Improved Accuracy in Fundus Observation

Designed with prisms that expand the binocular viewing range, it provides clear stereoscopic images. This enables high-precision binocular observation, enhancing the quality of fundus examinations.

Prisms that adjust the stereo angle expand the binocular viewing range, increasing the stereoscopic viewing area to approximately 133% compared to the 700GL model. This allows clear and detailed stereoscopic visualization of fine fundus structures. Additionally, the smaller stereo angle is advantageous for stereoscopic observation in patients with small pupils. By adopting a design that minimizes the depth of the device, it maintains a reaching distance equivalent to the 700GL, ensuring that the distance to the patient remains short and the operator can easily reach the patient-supporting a comfortable examination environment.

Improving Examination Efficiency

By enhancing patient safety and reducing the burden on physicians, this system supports comfortable, smooth, and efficient examinations.

During fundus observation, pressing the knob upward activates the prism. The distance between the physician and the patient remains unchanged from normal observation, maintaining a smooth examination flow and a design that considers operational efficiency.

The power and connection cables are housed internally within the main unit, minimizing their external exposure. This reduces the risk of contact with the patient, enhances cleanliness, and ensures smooth handling and ease of operation.

The finger rest on the forehead support improves stability when using a front lens, reducing strain on the physician’s arm while also minimizing contact with the patient.

The slit illumination control knob and background illumination control knob, positioned around the joystick, are thoughtfully designed for comfort in size and tactile feel. Their intuitive one-handed operation allows adjustments while looking through the microscope. Additionally, the trigger button on top of the joystick enables image capture without releasing the joystick.

NSW functions further increase the precision of observations

In contrast to the 10° stereo angle of the 700GL, an angle of 4.1° is adopted for the NSW, ensuring a wider stereoscopic vision area. This makes it easier to observe the fundus in detail for highly accurate diagnosis.

700GL NSW is a factory option specification. Please note that the standard 700GL cannot be modified/converted to 700GL NSW after purchase. NSW is an acronym of “Narrow angle,” “Stereo,” and “Wide viewer.”

Switching to the NSW functions is easy. Simply press the knob at the bottom of the objective lens.

Highly accurate examinations and diagnoses with a more natural stereoscopic sense

The inter-optical path distance of 22 mm and the sharp slit illumination that uses a high-luminance LED with a 3500 K color temperature produce a clear observation image with a stereoscopic sense from the anterior eye parts to the fundus. Lesions and foreign matter can be identified clearly and in detail, supporting more accurate diagnosis.

Ergonomic design × LED = Efficient examination environment, friendly to both doctors and patients

To reduce the burden on doctors during long examinations and minimize fatigue, the design focuses on ease of use, from the size and positioning of the operating parts to their operational feel. This model uses an energy-saving LED light source which provides stable brightness over a long service life. This allows a design with built-in cables and reduces heat generation, contributing to enhanced patient safety.

The design consists of parts such as a large-diameter dimmer knob arranged functionally around the joystick for easy operation with one hand.

The size and feel of the large-diameter control knob are optimally designed for comfortable operation.

The front lens can be held in a stable position using the finger rest function of the forehead rest. This makes observations easier and reduces the burden on the doctor’s arms, while also minimizing contact with patients.
