Recording

Capturing images

A short click (t ≤ 0.8s) on the center of the

Mode Control knob captures an image.

Recording videos

A long click (t>0.8s) on the center of

the Mode Control knob starts video

recording. To stop the recording, repeat

the long click on the center of the knob.

Factory Camera Settings

Factory camera settings are optimized

for our customers. If any changes are

made, clicking on “restore to factory“

will return the camera to the optimized

ZEISS settings.

White Balance

The white balance can be adjusted, if

the colors in a white light image appear

unnatural. To obtain the best result,

please use the “One-shot-Auto” feature

and follow the instructions.

Light Intensity

Select the correct light intensity for your

observation. Rotate clockwise to increase

light intensity. Rotate counterclockwise to

decrease light intensity.

Focus

Focus on the detail of interest. Check to

see whether the image is focussed both

on screen and through the eyepieces.

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.

High Saturation.

Colors are very vivid.

Recommended Saturation.

Colors are natural.

White Balance

Adjust the red and blue to obtain a colder or warmer image.

Fluorescence

Mode

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.
