LFV/LFV2 Series

LNV Series

Even illumination on reflective object surfaces

Bright, even illumination across the entire field of view makes on-axis illumination systems
ideally suited for inspecting mirror-finish work for scratches etc.

LFV2-5 Series

LFV/LFV2/LFV2-CP Series

LFV2-5 Series.
The micro lens and illumination system
are combined in one unit, making the
system much easier to use than a
separate illumination system combined
with a standard f50 lens.
The field of view can be adjusted by
changing the macro lens on the lens
barrel.

LFV2 / LFV2-CP Series Features
The use of CCS's unique heat dissipating construction
minimizes temperature increases due to the heat
generation in LEDs, increasing the service life of the LED.
(Refer to page 103.)
LFV/LFV2-CP Series Features
The use of a half mirror with an anti-reflection coating
eliminates ghost images.
The viewing window is protected with optical glass,
preventing dust entry.
Coaxial lights with a lens mounting ring
are available. These lights can be
mounted directly to the threaded part of
the lens commonly used for mounting a
filter and are best suited for installation
in confined places. (Available in M25.5,
M27, and M30.5 models.)

The LNV-300 provides coaxial drop illmination for line
sensors. Chip LEDs are used to achieve ultra-even
illumination.

Illumination structure of LFV2-100

Examples of Coaxial Light Images

A half mirror aligns the diffused light from the
LED array to the same optical axis as the lens.

Inspecting for Bearing Face Damage

Bearing Periphery Inspection

Even small scratches are made
clearly visible, using an on-axis
illumination system.

With standard coaxial illumination,
the light is concentrated at the center
of the illumination area.

With the LNV-300, even lumination
is achived over a wide area.
