What is the linear phase?

The

linear phase stabilizes the movement axis for the object moving by the motion system. The created sliding movement has led some people to the device to refer to a linear slide, which is a linear component of the stage movement. Parts of linear or translation, phase include a platform and a base connected by a linear movement deposit and a guide. The system allows you to translate movement along one axis, whether it is an X, Y or Vertical Z axis.

The linear stage platform always moves in relation to its base. Movement is limited to one axis by the equipment of the device. The types of guides include ball bearings styles that provide short distances and low weight capacity and are the cheapest. Flexure guides are highly accurate and not worn, but have a short travel range. Conventional styles used with a linear stage are also common styles used with linear stages, crossed roller bearing, high -capacity cylindrical sleeves and guides of dovetail.

BU. When it is in manual configuration, the control knob on the lead screw indicates the angular position of the phase. In optical applications, the precise phases require higher accuracy than the lead bolt, so that a fine screw or micrometer is attached to the metal pad on the platform. Movement can also be controlled by a stepper engine to move in additions referred to as steps in movement applications.

DC engine with encoder can be integrated into a linear stage. Movement with a fixed addition does not apply to this type, so the scale is integrated into the phase and the encoder measures the position phase in relation to the scale. The location of the data is transferred to the controller that automatically moves the phase to the preset positions. Systems requiring more than one axis of movement can combine linear stages, such as a two -axis phase used for microscopes. The vertical movement is needed, the three -axis phases are used.

for movement systems is pAnusability important. ABBE error is a normal shift resulting from angular errors in the system. Other mistakes include pitch, rolling and rolling and accuracy of OS X and Y are dependent on the orthogonal alignment of the second axis. The linear phase may also include rotary and tilting controls, allowing up to six axes.
