Optional Accessories
Mounted onto the TV port of the
microscope main unit as an add-
on function, the focus pilot can
detect the focus point with high
accuracy and reproducibility.
Adjustment of the brightness
of the focus pattern is possible
according to the surface
condition, material, and other
characteristics of the target.
The internal 0.5
X optical system
enables a wide field of view on
the TV monitor. (A separate CCD
camera needs to be mounted.)
We offer options that support the ease of operation of measuring microscopes. A focus pilot that reduces the dispersion of the focusing
point, power revolving nosepiece and power focus unit that enable changing magnification and focusing by hand, a digital rotary head which
digitally measures angles, a rotary table with a fine feed wheel enabling smooth rotational movement of the target, and other options are highly
developed. Choose options such as polarization and differential interference contrast units which support metallographic microscope observation,
TV port adapter for setting the camera required for multiple users to simultaneously perform analysis and evaluation according to the application.
Note: Combination of MF-U B and
FP-05U is a factory-fit option.
Power Focus Unit
This is mounted onto
the left Z axis handle of
the main unit. Fine feed
focusing using the remote
power jog dial and seven-
speed coarse feed focusing
using the jog shuttle are
available.
This is an electrically driven
revolving nosepiece to be
mounted onto the MF-U Series.
The objective lens can be
specified using the remote
console box. The centering
mechanism is standard
equipment for the Bright-Field BF
model only.
Note: External lighting cannot be used with this product.

Mounted onto the TV camera port of the microscope main unit, the focus
pilot can detect the focus point with high accuracy and reproducibility.
An internal 0.5X optical system enables a wide field of view on the TV
monitor. (A separate CCD camera needs to be used.)
†Concentric circle pattern
†Slit pattern
• The point where either of the above patterns matches between the
upper and lower parts is the focus point.
• A pattern can be selected and the brightness can be adjusted according
to the surface characteristics of the target.
