Applications | PhotoIonizers

Effectively removes static charges from any object in any place.

Widely used in various application fields due to high versatility and ease-of-use.

A great feature of photoionization using soft X-rays is that it can remove static charges from any type of object without any bad effect on the object. Due to high versatility and ease-of-use, Hamamatsu PhotoIonizers are used in a wide range of application fields and help solve the problems caused by static electricity to boost the throughput and yield rate in manufacturing processes.

Liquid crystal and organic EL displays

The size and resolution of liquid crystal and organic EL displays keep on increasing, so appropriate measures must be taken to remove static charges on a larger surface area. PhotoIonizers cover a wide area to neutralize static charges down to 0 volts to eliminate problems caused by static charges in production processes, including defects caused by particle adhesion and electrostatic discharge (ESD) that may occur during component pickup.


The increasing degree of miniaturization and circuit integration of semiconductor devices makes them more vulnerable to static charges. This makes it essential to take measures against static charges since they damage or destroy internal circuitry or cause device defects due to particle adhesion or from electrostatic discharge (ESD) that may occur during pickup.


Static electricity charged on paper and films can cause ink to bleed, splatter or spatter as well as particle adhesion and paper alignment errors creating serious printing problems. Hamamatsu PhotoIonizers revolve those problems stemming from static charges and help maintain the desired production efficiency and yield rate in the printing process.


Static electricity accumulates on the surface of films where they repeatedly make and break contact. An especially large amount of static electricity accumulates on films near the feed and take-up rollers. Hamamatsu PhotoIonizers neutralize the stored static charges that might otherwise emit sparks and damage (perforate) films or cause product defects due to particle adhesion or poor conditions in the work environment.


Electrostatically charged powder particles tend to easily adhere to nozzles and containers, which prevents packing and conveying powder in uniform amounts and causes serious problems such as drops in production efficiency and yield rates. Photoionization needs no air flow to remove static charges from powder particles and so can solve such problems that were impossible for conventional ionizers to handle.

Rechargeable batteries

Static electricity is likely to occur in a low humidity environments such as dry cleanrooms on production lines for products such as for rechargeable batteries, so sufficient measures must be taken to neutralize static electricity. PhotoIonizers can be used at these places to remove static charges that might damage (perforate) separator films or cause particle adhesion, thus preventing product defects and increasing the yield rate.


Coating and painting are utilized in countless applications including metal and plastic automotive parts. Static charges on such parts can cause coating materials to bleed, splatter or spatter and also cause particle adhesion, creating problems with coating and painting. PhotoIonizers can prevent such problems and thus improve coating and painting quality.
