The Different Types of Objectives
To meet the various requirements regarding
imaging properties, there is a choice of high-
quality interchangeable planachromatic and
planapochromatic objectives and also lower-
priced interchangeable achromatic objectives.
Achromatic objectives are particularly
suited for specimens with high-contrast
structures.
Flat-field (planachromatic) objectives are
particularly well suited for studying flat
objects such as wafers and thin sections.
With planapochromatic objectives, the
finest structures are visible with high
contrast. The sophisticated apochromatic
correction allows these objectives to attain
the highest color brilliance and fidelity.
Achromatic objectives
The 0.32×, 0.5×, 0.63×, 0.8×, 1×, 1.5×, 2×
achromatic objectives offer countless variants
for selecting the object field diameter, magnifi-
cation ranges and working distances (see page
54).
Planachromatic objective 1×
For the highest requirements for overall image
quality, we recommend equipping the micro-
scope with the 1× plan (flat-field) objective,
which returns sharp, contrast-rich object fields
all the way to the border.
Achromatic objectives with a long focal
length
For special applications, achromatic objectives
with long working distances and focal lengths
of f=100 mm to 400 mm are available.
