Focus Lens Kits - Universal Laser Systems M-360 Safety, Installation, Operation, And Basic Maintenance Manual

Focus Lens Kits

There are three optional Focus Lens Kits
available other than the standard 2.0", they
are the 1.5", 2.5", and the 4.0" kits. Included
in these kits are the focus lens, #3 mirror, front
plate, thumbscrews, and a focus tool.
Different lenses produce different spot sizes and have different focal ranges. For example, the 1.5" lens
produces a spot size of .003" and has an effective focal range of +/- .075". This lens can engrave very
fine detail but can only be used on very flat materials. On
the opposite end, the 4.0" lens has a spot size of .013"
but has an effective focal range of +/- .2". Although this
lens cannot engrave very fine detail, its focal range
allows you to engrave on slightly rounded or curved
objects without the need for rotation. Using a baseball as
an example, focus the beam halfway between the highest
point and the lowest point of engraving. Since a 4.0" lens
has a greater focal range than a shorter lens, you can
engrave a considerable distance around the ball without
having to rotate it. Attempting to engrave further around
the ball will result in a loss of engraving power and a
distorted image.
Refer to the following chart for spot sizes and focal ranges of the lenses available.
Rotary Fixture
The Rotary Fixture has been designed to engrave
cylindrical objects. Two attachments come with the fixture,
a cone shaped disk attached to the motorized end of the
fixture and an inverted cone shaped disk attached to the
adjustable end of the fixture. These attachments are used
to hold wineglasses, mugs, cups, etc. To make it easier to
understand, we will illustrate a step-by-step procedure to
engrave an image on a glass.
NOTE: These instructions apply to many different models even if your system has a smaller or
larger field size.
Installation
•
Turn the laser system ON .
•
Make sure AUTOFOCUS is turned OFF because the Rotary Fixture was not designed to work with
AUTOFOCUS.
•
Remove any materials that may be underneath the engraving table and lower the table ALL THE
WAY down to the bottom or at least far enough down so that the focus carriage will clear the top of
the Rotary Fixture when it is installed on the table. Now, turn the laser system OFF .
