Camera cleaning

Avoiding the necessity of camera cleaning

When screwing/unscrewing the camera lens or dust cap, hold the camera with

the C-Mount / CS-Mount opening towards the floor as shown in figure 1. This

minimizes the possibility of any contaminants falling on the glass surface.

Always store cameras and lenses with dust-caps installed.

Identifying impurities

If you observe any image artefacts in your video preview of your Manta camera

you may have impurities either on the lens, filter/protection glass, or on the

sensor protection glass. Every Manta camera is cleaned prior to sealing and

shipment; however, impurities may develop due to handling or unclean envi-

ronments.

As shown in figure 2, 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. Parti-

cles can either rest loosely or can be more or less stuck to the optical surface.
