Fibre-optic light guides
Fibre-optic illuminators
available. Goose-neck guides can be clamped
to the microscope carrier. Manufacturers of
cold-light sources also supply various adapters
to enable goose-neck guides and ring lamps to
be attached to macroscopes.
Cold-light sources of the Leica CLS series
The Leica cold-light sources CLS50, CLS100,
CLS150 and CLS150D provide high-intensity,
flicker-free white light within a small space,
combined with the minimum generation of heat
on the specimen. The cold-light sources are
lightweight and compact. They are user-friendly
and maintenance-free. The fan is quiet. All
models in the CLS series have a mechanical
diaphragm for uniform illumination and constant
colour temperature at all illumination intensities
without altering the size of the illuminated field.
The comprehensive program of accessories
allows almost unlimited application of these
cold-light sources.
Regulating transformer
• Continuous adjustment of the light intensity
from 0–7V
• Pilot lamp shines at 6V
• Sockets for two illuminators
• Safety tested: LGA, GS, EN 60950, CCA
The incident lamps, and the coaxial illuminator
with halogen bulb, can be connected to the
0–7V/40VA (115V/230V) regulating transformer.
Step transformer
are commercially A low-priced transformer for powering an
incident- or coaxial lamp with halogen bulb.
Brightness adjustable in three steps, 4/5/6V.
Filter-slide housing
In, for example, photography using artificial
light, colour-compensating filters are required
in order to avoid colour shifts. The filter-slide
housing is supplied with two filter slides that
can be quickly slid into the beam path when
required.
