2.8 EXTERNAL LIGHTING SYSTEMS
In some direct part marking applications best reading results are obtained by using an
external lighting system. A series of accessory illuminators are available which cover a
variety of applications.
The LT-100 Cone Lighting System provides a circular symmetrical light source designed for
the following applications:
with uneven or noisy background surfaces
where dot peening or laser etching codes are directly marked onto metal surfaces or
PCBs and need to be highlighted
in the presence of highly reflective surfaces (metal, glass, etc.) causing direct reflections

The LT-200 Spot Lighting System provides a high intensity light source designed for the
following applications:
with uneven, noisy and scratched surfaces
where dot peening or laser etching codes are directly marked onto metal surfaces or
PCBs and need to be highlighted. Here the use of more than one Spot Light can remove
any shadowing effect.
in the presence of highly reflective surfaces (metal, glass, etc.) causing direct reflections.
Low light path to surface angles strongly reduce direct reflections.
