STATICMASTER™ ALPHA IONIZING BRUSH

Overview the Staticmaster™ Alpha Ionizing Brushes remain the best portable solution for eliminating dust and static attraction on optical surfaces. These devices are also suitable for use with photographic films, for cleaning scanners, compact discs, slides, lenses, and filters.

Electrostatic charges attract dust, lint and a variety of foreign particles. Especially in colder low humidity environments one may observe how dust can not simply be blown off a lens surface since the particle is immediately attracted back onto the lens, just as a magnet attracts iron filings. The amount of moisture present in the air can affect the conductivity of insulating materials and their ability to hold a static charge. The higher the moisture content in the air, the more conductive a material becomes. Conversely, the dryer the air is, the more insulative the material becomes allowing it to hold a greater charge. Although controlling humidity can be helpful, it is a very slow process and often does not afford sufficient reduction in charge to be a complete solution to the problems caused by static charging. The Staticmaster™ neutralizes these electrostatic charges, freeing dust or other similar particles for easy removal with the provided soft brush.

A negatively charged surface can be neutralized by positively charged ions (an atom minus one electron). Similarly, a positively charged surface can be neutralized by negative ions (an atom with an extra electron). Staticmaster™'s Polonium 210 element emits alpha particles (positively charged Helium atoms) from its nucleus that collide with molecules of air, thereby creating a supply of oxygen and nitrogen ions sufficient to neutralize both positive and negative static charges. The emitted Helium ion has sufficient energy to travel about three centimeters through the air. As the Helium ion travels it strips electrons from surrounding air molecules. Each gas molecule that loses an electron becomes a positive ion. The free electron quickly attaches to another gas molecule and it becomes a negative ion. So, each alpha particle that is emitted always creates one positive and one negative ion. Hence, alpha ionizers produce an intrinsically balanced output.
To obtain a license to manufacture and distribute these devices, the design passed a safety analysis and battery of tests mandated by state and federal agencies, and defined by ANSI/ISO standards. The quality assurance program is in place during the manufacturing processes, and these are reviewed and audited to assure compliance. Every alpha ionizer source provided in the Staticmaster™ is sealed between a base of silver, and a layer of gold. A final gold plating provides additional integrity. Each element is leak tested before shipment. It is completely safe to handle this alpha source since the particles can not pass through a sheet of paper, or human skin. And the element is protected by a protruding metal grill. These have now been in production for over 30 years, and during that time the only instances of contamination were when the integrity of an ionizer was compromised by physical abuse, such as by the drilling a hole through or cutting it.
The half-life of the radioactive material is 138 days. After 12 months have elapsed, the activity of the device has reduced to 15% of it original activity and should be the cartridge replaced to assure optimal static control of your process. In addition, the regulatory body that governs the manufacture and distribution of our devices requires that all our alpha products be inspected thirteen months after manufacture. By returning the Polonium Cartridge the required testing can be done on our customer's behalf. Regardless of the cartridge half life the Staticmaster™ remains useful as a brush decades.

Operation first please refer to our article Cleaning Most Consumer Optics, a short illustrated "how to" including a decision tree "flow-chart" with a discussion of particle removing techniques, use of brushes, and solvents.

For maximum effectiveness pass the open grid area of the Staticmaster™ so that the Polonium 210 element is about one inch from the surface to be neutralized; no contact of the brush to the surface is necessary for this to work. Keep the target of this treatment isolated from any source of electrostatic charges since is it possibly to recharge a surface by means of capacitance where the charge migrates from one surface to another then back again.

When the relative humidity is very low, then the static voltages may be regenerated by the friction of the brush moving along the surface even though the surface may appear to be effectively cleaned. This can be overcome by again passing the part of the brush housing the Polonium over the object without having the soft brush make contact. To obtain better performance for the 2.5 inch brush element, you may retract the soft brush into its stored position. One or two passes should suffice.

Try to avoid having to clean oils from he brush, so do not touch the brush with bare hands and whenever practical wash hands with soap and water before cleaning a lens or mirror. Store the Staticmaster™ so that it is protected from contamination or crushing damage.

Cleaning the Staticmaster™ it may be possible to blow particles off the brush, use a bulb aspirator or regulated compressed air. If the brush has swept across areas contaminated with oily contaminants including eyelash oils or fingerprints then it will become necessary to clean the brush with mild detergent or alcohol. If using a detergent insure it is either an approved lens cleaning detergent solution, do not use other harsh cleaning solvents and do not use acetone. We prefer prefer to use alcohol; simply dip the brush in and out of a small cup of alcohol and gently wipe it dry with a soft cloth. Do not pull on the brush hairs.

The Alpha ionizer component should never be cleaned using any type of solvent or aqueous solution. If dust or dirt has settled in your device, it can be blown off using clean and dry compressed air. If using compressed air is not sufficient to clean the debris from the device, it should be returned for evaluation.
Features of a lens cleaning brush been pretty well exceeded with the Staticmaster™:

* Polonium 210 neutralizes static cling.

* Polonium is replaceable, date stamped, and easily exchanged

* In normal use will not fog photographic film.

* 2.5" Model features a brush section that retracts into a more compact profile.

* 2.5" Model can be joined side by side with optional connector.

* Brush easily cleaned with alcohol.

* Good quality materials, resistant to rust or corrosion.
