7.3 Parfocality adjustment
In order to have the same focus when observing the specimen through the eyepieces and on the screen/moni-
tor, please verify the microscope is properly installed and set and follow the instructions below.
In case of a biological microscope:
1. Use a low power objective and focus the specimen
2. Switch to the highest dry objective available on the microscope (40x or 60x) and focus the specimen again
3. Turn on the live-view on the camera, without changing the focus on the microscope
4. While observing the image on the screen/monitor, adjust the focus by turning the knurled knob on the C-
mount adapter
In case of a stereomicroscope:
5. Using a low power magnication and focus the specimen
6. Reach the highest magnication available using the zoom knob and then focus the specimen again
7. Turn on the live-view on the camera, without changing the focus on the microscope
8. While observing the image on the screen/monitor, adjust the focus by turning the knurled knob on the C-
mount adapter
The proper parfocality adjustment is obtained when the same focus is reached when looking into the eyepieces
and on the screen/monitor.

8.1.1 “Focus” Section
It is possible to work either in autofocus (AF) or manual focus (MF).
Clicking on “AF” button will allow the camera to work in autofocus mode.
It will be su󰀩cient to position the target to be observed in front of the camera lens and the focus will be obtained.
The autofocus will be independent of the optical or digital zoom value of the camera: the camera must have
enough contrast in the sample to be observed.
In the case of objects with low contrast, it is possible that the camera can not get the focus. In this case we re-
commend using manual focus.
• Itisimportanttoremindthatthecameradoesn’thaveaninnityautofocuscapability.Theusermust
approximately focus the specimen with the microscope focusing knobs. From this moment the cam-
era will be able to automatically focus the specimen when the stage is moved to another position or
the slide is changed on the stage.
Clicking on “MF” button, the camera will work in manual focus mode. Activation of the MF button automatically
activate the “MF” slider ①, with which you can operate to focus the camera without having to act on the
microscope focusing knobs.
Clicking on “Click F” the camera is taught which is the optimal focus for the sample that is being observed. From
now on, any movement that will be made on the sample or any change in zoom will have to be compensated
again with a new focus.
If you work in “AF” mode, this operation will not be necessary.
8.1.2 “AF ROI” Section
In the “AF ROI” section it is possible to set the size and the position of the ROI (Region Of Interest) where the
autofocus will be detected.
①

Page 11
ROI size can be either “Large” or Small”. This can be selected by clicking on the arrow ②.
A drop down list will appear. Here it is possible to select te size of the ROI area.
Clicking on the radio button “ROI” ③ will activate or deactivate the ROI.
②
LARGE
SMALL

Page 12
ROI can also be moved horizontally or vertically by using the two sliders “Hor” and “Ver” ④, in order to move
the ROI in the position where the user wants the autofocus will be detected.
Horizontal movement ranges from 0 to 16, while vertical movement ranges from 0 to 14.
Clicking on “Set” ⑤ will apply all the settings.
8.1.3 “Exposure” Section
“Exposure” section controls the exposure time and the brightness of the camera.
The camera can work in automatic exposure.
By activating the “AE” function, the camera works completely automatically. In this case it is not possible to act
on the parameters of the camera, therefore in situations of insufficient lighting it is possible that the camera can
not provide optimal image quality.
By activating the “ME” the camera works manually. It is therefore necessary to act on the camera parameters to
adapt the exposure time to the lighting condition of the sample.
Moving the slider relative to “Bright” increases or decreases the exposure time of the camera. Depending on
the amount of light that is used to illuminate the sample under examination, you will have to move to the right
(increase) or to the left (decrease) the cursor to get a perfectly lit image avoiding under or overexposure.
The cursor relative to the “Gain” commands the so-called “gain” of the camera. The gain is a function that allows
you to increase the sensitivity of the camera for shooting in low light. This obviously increases the background
noise.

8.1.4 “Color” Section
The “Color”section controls the color rendering of the camera.
Activating the “AWB” function, the camera uses automatic white balance. Place an empty slide on the micro-
scope front of the camera sensor and click “AWB”. The camera adjusts the colors output from the camera to the
color temperature of the scene being shot.
Activating the “MWB” function, the camera uses manual white balance. In this case it is necessary to move the
sliders related to Red, Green and Blue to obtain a faithful reproduction of what is being observed.
8.1.5 “Function” Section
“Function” section controls the image display on the monitor.
The “Ezoom” cursor ① allows to vary the magnification of the projection to the monitor of the framed object.
It is possible to change the zoom factor (optical zoom) from 0 to 50 operating on the on the cursor in the on-
screen panel.
①

Page 14
Camera allows to capture single images or videos simply by clicking on the “Capture” ② button for single im-
ages or on “Video” ③ for film sequences of desired length.
Still images or video will be stored on the SD card.
To view images or video the user must remove the SD card , simply pushing down the card. The internal locking
mechanism will release the SD card that can be freely removed from its slot.
To re-insert the SD card: fully insert the card and push it downward until the locking mechanism is engaged.
“FBL” button ④ fully disable the autofocus function of the camera, putting back the sensor motor to the so-called
“zero position”.
By clicking “AF” button or “MF” button again, the camera will allow to obtain an automatic or manual focus.
The “Flip” ⑤ function flips the framed image vertically, while the “Mirror” ⑥ function horizontally flips it. This is
useful for making what is observed in the camera consistent with the real object.

Page 15
The “HDR” function ⑦ (High Dynamic Range) optimizes the image quality in the case of subjects with very clear
framed areas together with very dark areas. Often in these conditions the camera favors or clear areas (omitting
the dark areas making them black) or dark areas (with a consequent overexposure of the light areas, making
them almost white).
An “HDR” setting of 0 indicates that the camera will acquire a single image and store it. Increasing the number
(max 3) the camera acquires 3 images at different exposures (usually an underexposure, one with optimal
exposure and one overexposed), combines them to optimize the different zones with different lighting and
creates a single image at exposure “virtually correct”.
The “50 / 60Hz” function ⑧ is used to eliminate flickering of the image due to the power supply frequency.

8.2 “Crosshair” Menu
Up to 4 sets of horizontal or vertical rows can be superimposed on the monitor.
These lines can be placed anywhere on the monitor by simply dragging the cursor relative to the desired line.
The lines can be projected with different colors in order to be easily visible on the monitor, depending on the
color of the sample in question.
Clicking with the mouse on the color palette of the desired row opens the context menu, with which you select
the color of choice.

Page 18
The lines, once traced, can be visible or hidden. Clicking on the “Show / Hide” button opens the context menu
with which you can view a “Show” row or hide it “Hide”. The lines, if hidden, will not be deleted from memory but
simply will not be visible.
The “Default” key resets all the settings made and restores the factory settings.
The “Center” button places the lines exactly in the center of the monitor (possibly overlapping the different lines
drawn).
The “Save” button saves the settings of the placed rows.
8.3 “System” Menu
With this menu, the system information of the camera is changed.
The “Edit Time” button changes the current date and time, while the “Save Time” button saves the settings made
just recently.
It is possible to change the menu language from English to Chinese.
The “Information” field displays the current version of the software.

9. Maintenance
To think about when and after using the system
• The system should always be kept vertically when moving it and be careful so that no moving parts,
such as the eyepieces, fall out.
• Never mishandle or impose unnecessary force on the device.
• Never attempt to service the device yourself.
• After use, cover the microscope with the provided dust-cover, and keep it in a dry and clean place.
Electrical safety precautions
• Before plugging in the power supply, make sure that the supplying voltage of your region matches
with the operation voltage of the equipment and that the lamp switch is in o󰀨-position.
• Users should observe all safety regulations of the region. The equipment has acquired the CE safety
label. However, users do have full responsibility to use this equipment safely.
Cleaning the optics
• If the optical parts need to be cleaned try rst to: use compressed air.
• If that is not su󰀩cient: use a soft lint-free piece of cloth with water and a mild detergent.
• And as a nal option: use the piece of cloth moistened with a 3:7 mixture of ethanol and ether.
• Note: ethanol and ether are highly ammable liquids. Do not use them near a heat source, near sparks or
near electric equipment. Use these chemicals in a well ventilated room.
• Remember to never wipe the surface of any optical items with your hands. Fingerprints can damage the
optics.
• Do not disassemble objectives or eyepieces in attempt to clean them.
For the best results, use the OPTIKA cleaning kit (see catalogue).
If you need to send the microscope to Optika for maintenance, please use the original packaging.
