INTRODUCTION

2.9 EXTERNAL LIGHTING SYSTEMS

In some direct part marking applications best reading results are obtained by using an

external lighting system.

The LT-700 Linear Array 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 LT-700 at different

positions 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.
