Optics

Clear observation of both the anterior and posterior segments of the eye

An inter-optical path distance of 22 mm is used to provide a balanced three-dimensional view of both the anterior and posterior segments of the eye. The eyepiece unit with a binocular stereo angle of 10° convergence helps to realise easy fusion and stress-free observation. On both the 2ZL and 4ZL the focal length of the objective lens (distance from the objective lens to the subject) is set at 125 mm to ensure a wide object fi eld, and in so doing maximising the volume of information acquired.

Wide range of filters included

As standard The 2ZL and 4ZL come with a wide range of filters included as standard. The blue correction fi lter protects patients’ eyes from harmful light while leveraging the merits of LEDs. It also has the effect of producing a colour tone similar to that of a halogen lamp, while preventing harmful light damage. The blue fi lter is effective for fl uorescein staining observations and the green (red-free) fi lter can be used for contrast enhancement, meaning that a diverse range of observations can be easily conducted.

Latest TAKAGI LED technologies

The 2ZL and 4ZL are designed specifi cally for LED light sources and provide a natural warm white colour similar to that of halogen and sharp slit illumination. The lamp unit uses a specially designed LED light source, virtually eliminating all concerns about bulb replacement for the lifetime of the product.

Uniform LED light source provides bright and sharp illumination.

A single 1-element, high-luminance LED is used to realise a stable and uniform slit illumination by controlling the colour variations and irregularities inherent in LEDs. The bright and sharp light makes it possible to clearly see the details of hard-to-discern microstructures in the eye.

Design

Functional beauty that realises a safe, clean and comfortable examination environment

Adopting a ground-breaking design that keeps all cables, including power cables, out of sight and unexposed makes it possible to eliminate damage to cables caused by external factors, and so greatly reduces potential causes of failure. The ST-50 Smart Table, which has no exposed mechanical parts, and the CR-750S Motorized Patient Chair, which can be raised and lowered using buttons on the ST-50, can be used together to enhance convenience, ensuring an examination environment that is safe, comfortable and exudes a sense of cleanliness.
