9.1.
3W – LED Transmitted light
For a research of transmitted objects it can be
helpful to observe the objects not only in incident
light illumination. The use of transmitted light
illumination is good to define structures much
more better.

Please note: The 3W-LED transmitted light can
be only used in combination with stage carrier
with object guide.

Further it is necessary to use a condenser. The
condenser comes with a wide field lens and an
aperture stop.
9.2.
Oblique incident light (dark field)
For a lot of objects dark field will most suited –
contours have a high contrast; finest structures,
reliefs, damages on surfaces are much more
better visible than with bright field illumination.
The equipment comes with an articulated arm
and a 3W-LED incident light illuminator,
focusable and a transformer for the 3W-LED
illumination, adjustable. This illumination is suited
for the objectives 5x; 10x; 20x.
