Leica M80 - Types of Objectives

Leica M-series User Manual 48
The Dierent 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-eld (planachromatic) objectives are
particularly well suited for studying at
objects such as wafers and thin sections.
★ With planapochromatic objectives, the
nest structures are visible with high
contrast. The sophisticated apochromatic
correction allows these objectives to attain
the highest color brilliance and delity.
Achromatic objectives
The 0.32×, 0.5×, 0.63×, 0.8×, 1×, 1.5×, 2× achro-
matic objectives oer countless variants for
selecting the object eld diameter, magnication
ranges and working distances (see page 63).
Planachromatic objective 1×
For the highest requirements for overall image
quality, we recommend equipping the micro-
scope with the 1× plan (at-eld) objective,
which returns sharp, contrast-rich object elds.
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.
