Leica L2 User manual 3
To you, the user
Thank you for purchasing the Leica L2 fibre-optic light
source. We wish you every success with this quality
product.
The Leica L2 fibre-optic light source provides excellent
illumination conditions for working with a stereomicro-
scope in laboratory and industrial settings. The antistatic
housing protects the equipment against the build-up of
electrostatic charges that can have serious effects
during the assembly and quality control of sensitive
electronic components such as circuit boards, integrated
circuits and reader heads.
The Leica L2 fibre-optic light source is a compact, power-
ful, competitively-priced unit which, when combined with
various light guides and accessories, is suitable for a
wide range of applications. By means of various adapters
it can be attached to any Leica stereomicroscope, or it
can be used as a free-standing lamp.
In developing this new fibre-optic light source we made
simple, self-explanatory directions a priority. We have,
however, put a lot of effort into explaining all functions to
you by means of a combination of pictures and text. You
will only get the best out of your fibre-optic light source if
you take the trouble to study this user manual in detail,
paying particular attention to the notes regarding the
safety of electrical appliances.
If you have any questions at any time, just contact your
local Leica agency or get in touch directly with Leica
Microsystems (Switzerland) Ltd, CH-9435 Heerbrugg. We
will be glad to help you. Customer service is a big thing
with us. Not only before the sale, but afterwards as well.

Before you try to use the Leica L2 fibre-optic light source
and its fibre-optic light guide, please read:
• this user manual and the safety notes
• the user manual for your stereomicroscope or
macroscope, including the directions for care and
safety.
If safety instructions are not observed, the safety of the
equipment cannot be guaranteed. The manufacturer
cannot be held responsible for damage or injury caused
by failure to comply with the contents of this user
manual.
The Leica L2 fibre-optic light source with its fibre-optic
light guides is the preferred illuminator for the Leica S4 E,
S6 E, S6, S6 T, S6 D and S8 APO. It can also be adapted to
the Leica MS5, MZ6, MZ75, MZ95, MZ125and MZ APO
stereomicroscopes and to the Leica M420; alternatively it
can be used as a free-standing light source.
The Leica L2 is designed for laboratory and industrial
applications, and serves to provide powerful illumination
for all types of object so that they can be observed under
the stereomicroscope. With this in mind, the infrared
range is filtered out and the visible component of the
radiation is transmitted to the object through flexible
fibre-optic light guides. The housing of the Leica L2 is
made of antistatic material, providing maximum
protection against electrostatic discharge. The Leica
L2 is silent and free of vibrations; a 20W bulb is used,
so there is no need for a fan.

6Leica L2 User manual – Safety concept

Be careful when handling liquids. If spilt on the equipment,
they can:
– cause the light source to become electrically live,
endangering personnel
– cause damage to the equipment.
– The Leica L2 fibre-optic light source is to be operated
only in conjunction with the original power supply unit.
– The power supply unit is to be operated only at the
stipulated mains voltages of 100 to 240V (50/60Hz).
– Always connect the power supply unit to the lamp
before you connect it to the mains supply (see page 16).
– To ensure that the equipment is completely discon-
nected from the mains, unplug the power supply unit.
Inspect cables regularly for damage. Defective cables
can:
– directly endanger personnel
– cause the instrument and other equipment to become
electrically live, endangering personnel.
Position cables with care. Make sure that personnel
do not get entangled with them. The instrument could
fall over, fall down, become damaged, damage other
equipment, or cause personal injury.

Safety precautions during use

The Leica L2 fibre-optic light source:
– must always be locked into an adapter when it is in
use (see page 14). This ensures its stability.
– must only be used in a vertical position with the light-
guide connector at the top (see page 14).
– must be set up so that all ventilation holes are free
(see page 14).
– Unplug the power cable from the mains socket.
– Never touch the inside of the lamp housing when
the power supply is connected.
– Wait for the halogen bulb to cool before you try to
change it. If you touch a hot bulb, you may suffer
burns. There is a warning symbol inside the door
of the lamp compartment as a reminder (see page 21).

8Leica L2 User manual – Safety precautions during use

– Never place anything over the open connection to the
light guide. The material covering the connection
could be damaged by heat.
– Never use any part of your body to cover the open
connection to the light guide; you could suffer burns.
– Make sure that the connections to the light guides
are at least several centimetres away from any
materials or objects which are sensitive to heat. The
amount of heat radiation emitted from the light-guide
outlet of a fibre-optic light source is negligible, but it
is possible for objects to convert the intense visible
radiation into heat and to become damaged.
Minimize the time during which the object is illumi-
nated, and also the light intensity.
– When detaching the light guide, avoid touching the
hot inlet of the light guide. Switch off the light source
and wait until the light guide has cooled down.
Immediately above the light guide inlet is shrink-on
tubing that enables the hot light guide to be touched
without danger.
– Do not look directly into the open connector of the
light guide; you could be temporarily dazzled. First
switch off the bulb before you pull out the light guide.
