Photographic Solutions BrushOff Sensor Cleaning Brush
BRUSHOFF, by Photographic Solutions, Inc., is unlike any other sensor brush on the market. 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.
BRUSHOFF's unique blend of extremely fine fibers, softer than a lady's blush brush, provides not only a conductive path, but includes fibers with characteristics that make the debris want to mechanically cling to them. The debris is removed from the camera with the brush.
BRUSHOFF utilizes an especially designed microscopically fine special filament. This fiber acts as the "vacuum" to pick up negatively charged dust from the positively charged sensor.
Another feature found only on BRUSHOFF is the grounding plug which works because it provides a path to ground for the charges on both the debris and the sensor. While normally a human can briefly serve as a ground for small charges, in fact, if the human is ungrounded, the body electr onically acts like a capacitor, not a ground. The human body can also be a lightening bolt to the sensor if it has a static charge. Just walking across the carpet on a dry day, a person can generate a 30,000v charge [that is what causes the spark between your finger and the doorknob]. The grounding plug insures that, regardless of any charges around it, the brush is grounded and electronically neutral. The plastic handle itself is a non-conductor which isolates the human from the brush. This allows the brush to be used in the field, away from any grounding source until one can locate a ground and discharge the BRUSHOFF.
Cleaning the BRUSHOFF is also quite simple. Use a clean PEC*PAD to wipe the bristles and dispose of the PAD. A 10 sheet package is provided with each BRUSHOFF
