Cleaning optical components

Mako G Technical Manual V4.2.2
Keep optical components clean
The best way to ensure the camera remains clean is to avoid penetration of foreign
substances into the camera.
When screwing/unscrewing the camera lens or dust cap, hold the camera with the
C-Mount / CS-Mount opening towards the floor. This minimizes the possibility of
any contaminants falling on the glass surface. Always store cameras and lenses
with dust-caps on.
Identifying impurities
If you observe any image artifacts in your video preview of your Mako G camera
you may have impurities either on the lens, filter/protection glass, or on the sensor
protection glass. Every Mako G camera is cleaned prior to sealing and shipment;
however, impurities may develop due to handling or unclean environments.
As shown in figure
, impurities (dust, particles or fluids) on the sensor or optical
components appear as a dark area, patch or spot on the image and remain fixed in
the preview window while you rotate the camera over the target.
Do not confuse this with a pixel defect which appears as a distinct point. Particles
can either rest loosely or can be more or less stuck to the optical surface.
Locating impurities
Before you dismount the lens you should find out if the impurity is on the filter,
lens, or sensor.
