3.2.2 Adjusting the field size with the centre hand grip

By turning the sterilizable centre 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.

3.2.3Adjusting the field size - light field plotting model LFN (option only D 650plus, D 650)

The CHROMOPHARE

D 650plus and D 650 with light field plotting allows the field size to be adjusted by an

electric motor.

By pressing and holding down Key 8 (see control unit page 14) the light field is continuously enlarged up to the

maximum value. By repeated short presses the light field is enlarged in steps.

By pressing and holding down Key 9 (see control unit page 14) the light field is continuously reduced down to the

minimum value. By repeated short presses the light field is reduced in steps.
