Swan neck light guide (Fig. 41/ 1 ) with two
focusing attachments
(Fig. 41/
2
)
−
Illumination: variable oblique reflected light
illumination (both sides)
−
Application: Observation of spatial objects with
selective shadow effect. The three-
dimensionality of the object is strongly
highlighted, while avoiding dark drop shadows.
The flatter the swan-neck arms light
up the object, the stronger the 3D
effect, but also shadow formation.
Single-arm swan-neck light guides
with a strong shadow effect can also
be used
−
Further accessories for flexible light guides and swan-neck light guides:
•
Polarization filter
−
Application: Minimization of mirroring reflexes and disturbing luster
−
Assembly: Screw the polarizers into the focusing attachments. Insert the analyzer onto the objective
and secure.
−
Operation: Turn each polarizer separately until the disturbing reflexes are reduced to the desired
level. Once all polarizers are adjusted, all mirror reflexes can be simultaneously weakened or
intensified by turning the analyzer.
Fiber optic diffuser S, retractable
(Fig. 42/
1
)
−
Illumination: all-side, diffuse reflected light
−
Application: low-reflex illumination of shiny
three-dimensional objects. Shiny object parts
appear bright, but without dazzling.
−
Assembly: Then push the diffuser S onto the
objective until it engages and secure it.
Suitable for objectives with a working
distance of 60 mm and more.
−
Operation:
•
If necessary, pull the outer sleeve of the diffuser
(Fig. 42/
1a ) downwards to intensify the light
effect on the object.
•
Align the beam direction of the incoming light guide to the object as necessary to prevent residual
reflexes.
•
A gliding or roller stage is recommended for optimum object alignment in the observation of three-
dimensional, shiny object parts.
