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.

The background illumination uses an LED with the same color temperature as the slit illumination to obtain a clear image without impairing the color balance.
This makes the entire eye easy to view, allowing the position and condition of affected areas to be communicated intuitively to patients.

Press a single button to capture images while operating the joystick.

A camera for capturing images can be connected by installing a combination adapter or camera adapter made by TAKAGI.

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

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, 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 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 Tiltable Binocular Tube O12-20 or the 13-degree Tilt Adapter S06-59 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 color 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 color tone.

The Diffuser for widely and evenly illuminating the anterior segment is included as standard.

The background illumination and Diffuser can be used selectively according to observation conditions, allowing for a flexible imaging environment.

This is especially effective when using filters, as the Diffuser helps to evenly diffuse the light.

This makes it possible to select illumination according to the observation method.

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.
