2.1 Product designation, intended use
Manufacturer’s name: Auto Focus
The Auto Focus is designed for use with the Axio Imager 2 and Axio Imager Vario stands with motorized
focus. The left camera deflection port serves as the point of coupling.
Auto Focus allows the focal plane to be found automatically and quickly on the sample surfaces and to
be maintained when moving the samples along the X or Y axis, or to be adjusted in line with the surface
structure.
The focus adjustment is carried out automatically by the focus controller, which controls the motorized
focus drive (Z axis) of the microscope.
Use of Auto Focus is recommended for reflective samples such as semiconductors or metals. It is
distinguished by its considerably shorter control time in comparison to the software autofocus function
and its wide capture range of several hundred depths of field.
The suitability of Auto Focus should be checked for all other surface properties (e.g. partially reflective,
diffuse). A selection of different samples / surface properties can be found in Table 3 on page 26.
2.2 Restrictions
The capture range and the accuracy of Auto Focus (see Table 2, page 15) should be taken into
consideration for the different objective magnifications. These differ depending on the system
configuration, work mode and sample surface. The maximum capture range of Auto Focus (see Table 2,
page 15) has been set using highly reflective samples.
Optimum quality of the Auto Focus signal can only be guaranteed if the special left camera deflection for
the Auto Focus is used with the appropriate Auto Focus installation set.
Use of the camera deflection prevents use of the Analyzer slider (fixed or rotatable). For transmitted light
applications requiring a rotating polarizer / analyzer, the rotating polarizer (427706-0000-000) and the
P&C reflector module (424941-9050-000) can be used, and for reflected light applications, the rotating
polarizer (427704-9901-000) and the P&C reflector module (424941-9050-000) can be used.
The DIC / Pol ACR P&C reflector module (424939-0000-000) can be used for reflected light polarization
applications with fixed polarizers and for DIC applications.
Use of the brightfield reflector module (424928-9901-000) is only possible without grey filter.
Use of the Auto Focus equipment may be limited with polarization applications, especially at greater
magnifications.
Use of Auto Focus may be limited with DIC applications.
Use of Auto Focus with C-DIC and fluorescence applications is not possible.
Use of a linear focus sensor (430703-0000-000) for Axio Imager 2 and for Axio Imager Vario (425300-
9000-000) in combination with Auto Focus is not possible.
