The FS-300 is designed for inspecting microcomponents such as
IC chips and video head parts. The optical system features ultra-
long working distance objectives, wide view field eyepieces, and
independent correction for lateral chromatic aberration.
FEATURES
• The complete system of FS-300 can be composed of a variety of
parts for meeting diverse applications.
• Available with or without a transmitted illuminator.
• Ultra-long working distance objectives provide easy
manipulation of workpieces.
• Easy switching between the bright-field illumination and the
dark-field illumination.
• Optional accessories widen the range of applications.
Polarized light observation:
Observing only the filtered light that
vibrates in one direction. Used for
observing materials with special
optical characteristics, such as
mineral and liquid crystal.
Differential interference
observation:
Effective in detecting fine scratches
and steps on the surface of metal,
liquid crystal, and semiconductors.
Bright field observation:
Most common method of
observation. Observing directly the
light reflected on the surface of
workpiece.
Dark field observation:
Observing only the scattered light by
shutting down the direct light to the
objectives. The scratches and dust
that cannot be viewed in the bright
view field can be observed by a high-
contrast.
