Operation

Switching on the illumination Caution The light source in this unit may be too bright at shorter focal lengths for surgeon and patient. ➩Start with light low and turn up till surgeon has an excellent optical image. Explanation light quantity The variable working distance of the M520 optics goes from 207–470 mm. The system is designed to have full light at 470 but not at 207 mm. According to the inverse square law Ev=Iv/d2 a constant light increases from 470 mm to 207 mm by a factor of 510 %. (Ev = illuminance; Iv = intensity; d =distance from the light source) Therefore a microscope with shorter working distances requires less light than longer working distances. A good practice is to start with the light low and to turn it up until the surgeon has an excellent optical image.

Switching from the main to the emergency illuminator Warning Failure of the illumination can be dangerous for the patient! ➩If the main illuminator fails, switch to the emergency illuminator immediately. ➩Use the rotary button (2) to switch from “Xenon” to “Halogen”. Replace the defective illumination at the next opportunity. Never begin an operation with only one functioning illumination unit. Only use the emergency illuminator for emergency use.

Explanation heat from light The heat produced from this xenon light source is filtered to not allow heat from non visible light (above 700 nm). However all white light contains heat. Excessive use of white light can cause over heating in the field of tissue and metal objects. A good practice is to start with the light low and to turn up until the surgeon has an excellent optical image. Always allow the main and emergency illuminators to remain lit for at least five minutes, otherwise the lighting capacity will be quickly reduced. ➩Switch on the main illuminator at the switch (3). ➩Adjust the brightness of the main illuminator with the rotary knob (1) if necessary. If the illumination is still too bright when the rotary knob is in the minimum position, this can be optimised by a small aperture at the microscope. This also increases the depth of field. Please contact your Leica service workshop in this case.
