…total area to be covered on
the work piece is below about 200 mm
x 200 mm.
Scan lenses come in two basic flavors,
f-theta and telecentric. F-theta lenses
derive their name from the fact that
focused spot position on the work piece
is related to the product of lens focal…

…combines precise mask projection with a high-speed
galvanometer laser beam scanning system. The
gravure is achieved by replacing the usual f-theta
lens with a simple focussing lens. The method is
very fast - allowing the use of full pulse speed of
the excimer laser - and economical…

The problem with the simplest type of f-theta lens is
that the focused beam hits the work piece at an angle.
For surface treatment applications, such as marking,
this may not be a problem (although the…
