The

Ocular

panel contains the following functions:

HAL On/Off

button for transmitted light: If the

button is pressed, the control panel appears and
the shutter automatically opens (Fig. 120). If you
press the

On

button, the light intensity of the HAL

lamp can be varied via the input box or slider. The
Light Path will be highlighted by color in the
diagram. Press the

On

button again to shut down

the light. The color temperature for photo
documentation can be switched on via

3200 K

button.

HAL Transmitted light Open/Close shutter

button: The shutter for transmitted light from the
HAL lamp is switched on and off by repeated
pressing.

Condensor

button: The Numerical aperture of the

condensor is set via input box or slider. The turret
position can be selected from graphical pop-up
menu (only for motorized condensors).

Stage

button: If the stage button is pressed, the

Stage control panel will appear (Fig. 121). By
pressing the

Stop

button you can interrupt any

stage movement. The

Move to Zero

button will

move the stage to the current zero positions of the
x and y coordinates. The compass rose will move
the stage in the direction of the arrowheads. Fast
movement is obtained with the outer rose, slow
movement with the inner rose. The

X-Position

(µm)

and

Y-Position (µm)

display boxes show the

actual x and y coordinates. You can edit the
numbers by typing or using the arrowheads. If
numbers were altered, the first click on the
compass rose will bring the stage to the altered
position. The

Step Size (µm)

display box show the

currently use step size for stage movement. The
value can be edited by typing or using the
arrowheads. The

Zero Position Set

button set sets

the x and y coordinates to 0.

Focus

button: If the focus button is pressed, the

Focus control panel will appear (Fig. 122). The

Z-Position

display box shows the current z position. The number can be edited by typing or using the

arrowheads. The nosepiece or stage will automatically update the new position. By pressing the

Stop

button, you can stop the current movement. The

Step Size (µm)

display box show the currently use step

size for stage movement. The value can be edited by typing or using the arrowheads. The

Home

button

sets the z position to the predefined 0 value. Pressing

Load

will lower the nose piece (z-position) for

objective change.

Work

brings the z-position back to the actual used position if the focus was zeroed or

in

Load

position. Home and Load positions can also be accessed from the z-position slider by pressing
