and follow the instructions.
5
Light Intensity
Select the correct light intensity for your
observation. Rotate clockwise to increase
light intensity. Rotate counterclockwise to
decrease light intensity.
6
Focus
Focus on the detail of interest. Check to
see whether the image is focussed both
on screen and through the eyepieces.
4
Magnication
Select the correct magnication to
obtain maximum information from the
intended image with the manual 5-step
apochromatic magnication changer.
Magnication factors: γ = 0.4x, γ = 0.6x,
γ = 1.0x, γ = 1.6x, γ = 2.5x
Parfocality
Follow these instructions to obtain a
focussed image both on the monitor
and through the eyepiece.
• Use the image on the monitor for
reference
• Set surgical microscope to its highest
magnication
• Focus image using Varioskop® 230
• Look through eyepieces
• Adjust diopters for left and right eye
until image sharpens

Detailed Setting Information
Parameter Before adjustment Adjusted Settings
Brightness Light Intensity
The front face of the OPMI features 5 white LED indicators arranged in an arc
above the Mode Control knob. These LEDs are designed to roughly indicate the
set intensity level of the illumination under the corresponding mode. Note that the
illumination intensity of each mode can be set independently and will be automatically
remembered by the microscope even after it is powered o.
Brightness
Adjust the brightness on the screen manually to
obtain a sharper image. Caution: This does not
aect the light intensity!
Overexposed image.
Details are not visible.
Recommended settings.
Details are visible.
Light Meter Field
The light exposure is measured in dierent areas
of the image. Choose between “small circle”, “big
circle” and “integral” to select the area.
Small Big Integral
Light Meter Mode
Select “Average” or “Peak” to select the exposure
limit. Choosing “Peak” allows you to adjust and
focus on the brightest point during the inspection.
Choosing “Average” provides a wider overview.
“Peak” setting “Average” setting
Exposure Control
Adjust the exposure manually for longer exposure
times (for e.g. Fluorescence Mode ). When using
manual exposure, avoid bright light around the
teeth. Choose between “Auto” and “Manual”.
Very short exposure time –
details cannot be analyzed due
to the darkness of the image.
Longer exposure time –
details can now be
analyzed.

Color Angle (Hue)
Adjust the color angle manually. Skin-colored objects will appear either more yellow or more purple.
Black Level (Lightness)
Adjust the black level manually to obtain a darker or brighter image. The black level is dened as the level of
brightness at the darkest (black) part of a visual image or the level of brightness at which no light is emitted
from a screen, resulting in a completely black screen.
Color Saturation
Adjust the color saturation manually to
obtain more or less vivid pictures.

Colors are very vivid.
Recommended Saturation.
Colors are natural.
White Balance
Adjust the red and blue to obtain a colder or warmer image.

When using the Fluorescence Mode,
avoid high light levels around your
working area. This can cause blurred,
red images. It is also advisable to
turn o the light on the handpiece.
Blurred Fluorescence Mode.
Red image caused by too much
light around the treatment area.
Optimal Fluorescence Mode.
Image recorded with lower light
levels around treatment area.
