4.5.1 Adjusting the field size

4.5.2 CHROMOPHARE

C 95x on the control panel

By pressing and holding down Key 4 (field size small) the light field is continuously reduced down to the mini-

mum value. Repeated short presses reduce the light field in steps.

By pressing and holding down Key 5 (field size large) the light field is continuously enlarged up to the maximum

value. Repeated short presses enlarge the light field in steps.

The surgeon must perform the optimum field setting himself in accordance with the size of the operation open-

ing. There is an optimum contrast when the field size is set approx. 2 - 3 cm larger than the operation opening, so

that the edge of the sterile covering is also illuminated. Thus the adaptation of the surgeon’s eyes in the whole field

of vision is improved.

4.5.3 Adjusting the field size with the center hand grip CHROMOPHARE

D 650plus, D 530plus

By turning the sterilizable center hand grip the size of the light field is changed. By turning the hand grip in the

clockwise direction the light field is enlarged, by turning anti-clockwise the light field is reduced. The surgeon must

perform the optimum field setting himself in accordance with the size of the operation opening. There is an opti-

mum contrast when the field size is set approx. 2 - 3 cm larger than the operation opening, so that the edge of the

sterile covering is also illuminated. Thus the adaptation of the surgeon’s eyes in the whole field of vision is im-

proved.

On CHROMOPHARE

D 650plus with the Light pilot option, the adaption of the field diameter is done at the

control panel (please see chapter 4.2).
