OPMI® PRO magis

Intended use

The OPMI® PRO magis surgical microscope is a compact and easy-to­use instrument which is ideally suited for neurosurgery, ENT applications
and reconstructive and plastic surgery. It is also suitable for the use in
other microsurgical disciplines.

The friction of the front-to-back and lateral tilt motion can be adjusted as
required. The tilt and rotary axes of the OPMI

®

PRO magis surgical micro­scope are equipped with magnetic brakes permitting the microscope to be
locked in any position.

The zoom and focusing functions of the OPMI

®

PRO magis surgical
microscope are motorized, and can be directly activated on the micros­cope. A foot control panel is not required for operation of the instrument.
However, you can also control the motorized functions via a foot control
panel or hand control panel. The magnetic brakes can be operated from
the microscope direct.

The coaxial illumination system is supplied with light via an S light guide.
The diameter of the illuminated field can be continuously adjusted from a
fully illuminated field (∅ 55 mm) to ”spot” illumination (∅ 11 mm) using a
light stop lever. This data applies to an objective focal length of f = 200
mm. With the ”spot” setting, luminance is approx. twice as high as in the
largest possible illuminated field.

You can equip the OPMI

®

PRO magis surgical microscope with all acces­sories required for documentation and coobservation. These accessories
can be mounted quickly and easily.

For adjustment of the depth of field, we recommend using a double iris di­aphragm. Cat. No. 30 33 54-0000.

Caution!

If the xenon light source is used, the unit must not be used in ophthalmic
applications. Severe injury to the patient's eye is possible.

Widefield eyepieces with magnetic coupling

Note:
When you remove these eyepieces from the tube, please note that they
are fitted with a magnetic coupling. When mounted, the eyepieces display
a very weak magnetic field, so that the usual rules for the handling of mag­nets must only be observed with eyepieces which have not been mounted
on the microscope:

• Do not place the eyepieces close to instruments where there is any

risk of magnetization.

• Do not place the eyepieces on sensitive electronic units such as infu-

sion pumps, cardiac pace-makers, measuring instruments or magnet­ic data carriers such as disks, audiotapes and videotapes, or credit
cards.

• Always store eyepieces not used in their original packaging.

1 Eyecup

Always adjust the eyecups in such a way that you can see the full field
of view.

– Viewing with eyeglass-

Screw in the eyecups all the way.

es:

– Viewing without eye-

glasses:

Screw out the eyecups until you see
the full field of view.

2 Diopter adjustment ring

The eyepieces provide ametropia compensation between -8 D and
+5 D. Eyeglass wearers who perform surgery wearing their glasses
set the diopter adjustment ring to 0 D. Turn the ring until you have ob­tained the optimum setting. An integrated brake holds the ring in the
position set.

– Avoid looking directly into the light source, e.g. into the microscope ob-

jective lens or into the light guide!

– When operating on the eye, always use a GG 475 protection filter to

ensure that the patient’s retina is not exposed to unnecessary (blue)
radiation (retinal injury)!

Care of the unit

Cleaning optical surfaces

The multilayer T* (T-star) coating of our optical components (e.g. eye­pieces, objective lenses) results in optimum image quality.
Image quality is impaired by even slight contamination of the optics or by
a fingerprint. In order to protect the internal optics from dust, the instru­ment should never be left without the objective lens, binocular tube and
eyepieces installed when it is not in use. Always store objective lenses,
eyepieces and accessories which are not being used in dust-free cases.

The external surfaces of optical components (eyepieces, objective
lenses) should only be cleaned when required:

• Do not use any chemical cleaning agents.

• Blow off dust on the optical surfaces using a squeeze blower or re­move the dust using a clean and grease-free brush.

Prevention of fogging

To prevent the eyepieces from fogging, you may treat them with our anti­fogging agent.
This anti-fogging agent consists of a dry, chemical solid in the form of a
stick and produces a dry film when applied to the eyepieces.
This film protects against fogging without causing any damage to the T*
coating. The anti-fogging agent contains neither wax nor silicone; it is un­poisonous and does not scratch glass.
The anti-fogging agent does not only ensure fog-free optics; it cleans and
protects the eyepiece optics against dirt, grease, dust, fluff and finger­prints.
Every pack of anti-fogging agent (contains 1 stick) includes instructions
for use which we would ask you to observe.

Important:
Spread the anti-fogging agent film with a dry cotton cloth - do not use
paper!

Anti-fogging agent: Cat. No. 30 55 50- 9910

Cleaning mechanical surfaces

All mechanical surfaces of the equipment can be cleaned by wiping with
a moist cloth. Do not use any aggressive or abrasive cleaning agents.

Wipe off any residue with a mixture of 50% ethyl alcohol and 50% distilled
water plus a dash of household dish-washing liquid.
