Features
& Benefits
Photographic Solutions’ “BRUSHOFF” Brush is unique in
the digital cleaning world.
BRUSHOFF™
is unlike any other sensor brush on the market. The BRUSHOFF design evolved
from a NASA design and engineered to meet their rigorous requirements
and specifications. It is not just an ordinary artist supply brush with
a fancy name and high price tag ! Hold the BRUSHOFF and one instantly
can see this is a solidly designed and built electronic tool utilizing
science to produce unparalleled cleaning power ! Although the brush head
is remarkably soft, the brush core is entirely electronically conductive,
through an ingeniously designed grounding plug.
BRUSHOFF
is conductive because the dust and lint that attaches to the sensor or
lens surface is attached there electronically [dust has a negative charge
and the sensor/ lens a positive one]. Breaking that electronic bond is
the only way to both remove the debris and discharge the sensor or lens
surface so new particles are not again immediately attracted to it. A
mere artist brush cannot clean all of the dust, nor can it prevent dust
accumulation, even immediately after its use.
To
draw a parallel, the sensor surface is much like the face of a computer
monitor. The dust is very hard to wipe off with a dry cloth. The result
of trying is better described as “dust rearrangement” rather
than “dust removal”. Use BRUSHOFF prove it to yourself - a
conductive brush can, if it is grounded, brush the dirt cleanly off the
computer screen just as it will off your sensor. No longer attracted,
the dust easily falls off.
As the amount of charge (and therefore the amount of attraction) on either
the sensor or the dust is unknown, using a fiber with a predetermined
amount of positive charge hoping to electronically “vacuum”
up the debris, may or may not remove all of the dust particles. It will
remove particles when the fiber’s positive charge is greater than
the sensor’s positive charge.
