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 of the forehead rest.
This makes observations easier and reduces the burden on the doctor’s arms, while also minimising contact with patients.

Background illumination in use

The background illumination uses an LED with the same colour temperature as the slit illumination to obtain a clear image without impairing the colour balance.
This makes the entire eye clearly visible, enabling patients to intuitively understand the location and condition of the affected area.

Simply pressing a button once to capture an image while operating the joystick.

A camera can be connected for imaging by attaching a TAKAGI combination or camera adapter. A TAKAGI digital camera is also available.

A single-element, high-luminance LED provides natural colour and a uniform slit beam. Rich light scatter enhances tissue contrast, enabling clear observation of the cornea, aqueous humour, lens, and vitreous humour.

The microscope features converging binocular tubes with a 6° convergence angle, making fusion easier and providing a natural sense of depth.

A wide 14 mm illumination field diameter is used to provide sufficient coverage for the cornea, which is approximately 11 mm in diameter.

Even if the eye moves slightly, the entire cornea remains within the illumination field, allowing stable observation.

The power and connection cables are housed internally within the main unit, minimising 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 minimising contact with the patient.

The slit illumination dimming knob and background illumination dimming 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.

Using optional components such as the O12-20 Tiltable Binocular Tube or the S06-59 13-degree Tilt Adapter helps reduce tension in the neck and shoulders, supporting a better work environment with more comfortable posture during examinations.

The use of high-eyepoint eyepieces makes observation easy even while wearing glasses.

There is no need to remove glasses during observation, enhancing convenience in the examination environment.

The background illumination is built into the main unit. Because it is not an external lighting unit, there is no concern about the physician’s hand interfering with protruding parts of the illumination.

The background LED uses the same specifications as the main illumination. Although it shares the same colour temperature, it operates independently from the main light, allowing both light sources to be adjusted freely. This enables well-balanced image capture with consistent brightness and colour tone.

*Image with Digital Camera Adapter S10-17 attached.

In addition to shooting with a mounted TAKAGI digital camera, a single-lens reflex camera can also be mounted using a camera adapter.

Image capture can be easily performed using the trigger button located on top of the joystick.
