Cleaning optical components

Mako U Technical Manual V1.1.3
Cleaning instructions
1. Disconnect the camera, including power supply, before cleaning.
2. Have the cleaning materials ready before you start the cleaning.
3. Apply a small amount of cleaning liquid to a clean, new lens cleaning pad or
tissue.
The pad or tissue should be moist, not dripping. Hold the camera away from
your body to avoid that particles like skin flakes fall onto the sensor.
The camera front should point roughly 45 degrees upwards.
4. Wipe the glass surface in either one of the two ways described below to ensure
any dirt present on the surface be moved to the edge of the surface:
a. With a spiral motion from the center to the rim. Normally, several spiral
wipes are recommended. Wipe only on glass avoiding contact to metal sur-
faces, because microscopic dirt could be released and could cause
scratches on the glass.
b. With a straight motion across the glass surface from one end to the
opposite end.
3. When you have finished cleaning, examine the surface in a strong light. Take an
out-of-focus picture of a flat, illuminated surface to see if any dirt remains.
Workplace conditions
•
Carry out all cleaning operations (on lenses, filter or protection glass, and
sensor) in a clean dust-free room.
