2.Application :
Produced as dielectric constant the vane part of Closed Loop
Galvanometer,suit for different kinds of Closed Loop Galvanometer
such as:***0H/***0H/***5H/VM***0/***0H/***1HC/***0H/MPM*0A/***0H
Note:above model by cambridge technology standard.
3.How it works?
Â
Â
Â
Â
The closed loop scanner adds an additional element. The
shaft is fitted with a position detector that can determine where
the scanner is within it's range of motion. In modern
high-speed scanners, the position detector uses an optical system
with a
vanethat occludes the light from an LED falling
onto a photo sensor. As the shaft moves through it's
range of motion, more or less light falls on the photo sensor
generating a signal that is proportional to the position of the
shaft and it's attached mirror.
Â
In the diagram above, the LED is shown in green and the photo
detector in light blue with an occluding vane attached to the
shaft between then. The closed loop scanner amplifier is
also more complex than the typical open loop scanner amp.
   The signal is sent to the scanner drive
stage circuit after passing through the conditioning
circuit. The position of the shaft (and it's attached
mirror) is derived from the photo detector in the position
detection circuit, which sends that signal to a position
correction circuit. The position correction circuit
compares the actual position of the mirror, with the position the
mirror should be in according to the signal from the
conditioning circuit. It then generate an error correction
signal and sends that to the scanner drive stage where it is
combined with the signal. The drive stage provides
the current to the coils in the scanner to move the mirror.
   The position of the mirror is thus compared in
real time with the signal and corrected for any
inaccuracy. This allows the very precise and accurate
control of the mirror that is necessary for projecting laser
graphics. Naturally, since this is a mechanical system,
there are limits to how fast the mirror can be moved.

4.The great advantages of our
alumina ceramic vane
Due to the excellent flatness of alumina ceramic
vance(Note:we can control the
tolerance from 0.*2 to 0.*1,so in fact the Flatness of some of
the ceramic vane after polishing can be 1.0*0.*3 or
1.0*0.*4)frequently. ,when it works,the alumina
ceramic vane deflect with the shaft,won’t affect the electric
voltage,so it keeping the all Closed Loop Galvanometer working
steadily,you don’t need the adjusting the device
