The CO2mpact range from ULO Optics is a cost-effective solution to low-power beam delivery that is easy to understand, easy to use and easy to order.
Laser users require high quality, low maintenance beam delivery components priced in proportion to their laser investment. Complex beam delivery systems can prove to be expensive if a skilled technician is required to spend many hours on alignment and maintenance. The new CO2mpact range has been specifically designed to address this issue. CO2mpact is a complete series of products that
fulfil beam handling requirements from the laser mount to the nozzle
tip. The units are suited to most CO2
lasers of up to 500 watts with clear apertures 16.4mm.
Each component of the CO2mpact Beam Delivery system is described here with its external dimensions in mm and main part numbers. For full information and technical drawings on each of the components please view the relevant technical datasheet. Example System The following drawing shows an example CO2mpact setup.

ULO
Optics' experienced and highly knowledgeable design team are happy to
provide system drawings upon request, to enable swift implementation
of your CO2mpact Beam Delivery system in to your Laser system.
A
range of laser mounts have been designed to enable the user to connect any
of the compact range directly to the laser of their choice. Mounts to suit
the most popular lasers are available, others could be manufactured on request.
Two types are offered. A fixed version for short beam paths or an adjustable
unit for longer paths or systems without mirror blocks.
Pipe supports are available in various optical axis heights. These are
to suit the exit heights at which the beam leaves the appropriate laser.
(Typically 73, 78, 81, and 123mm are available as standard). Others can
be supplied on request. 
Pipes are supplied in standard lengths as show in the parts list. Each
pipe is supplied with one internal coupling ring. The extender pipe can
be used to fill the in-between sizes, or could be used as a coarse focus
adjustment.
These
will be required if several components are coupled together and need to
be locked in a certain orientation.
Not
every system will need a beam expander. In general they can provide a
benefit, if the beam path is longer than 2m, or if a smaller focus
spot is required. Three magnifications are available, but it is important
you know the input size of the beam so the output does not exit too big
for the clear aperture of the system (ie 16.4mm when used in conjunction
with a mirror block). The compact beam expander has a slide and lock
focus setting. Normally this
is set
to
infinity
during manufacture. However, if a customer needs to adjust this to suit
their system, the output should be coupled to the adjustable pipe (C-BPE85/125)
so this too can be adjusted and maintain a fixed length. If required
Umicore Laser Optics have software that can trace your beam through the
system, so if you are in doubt please contact us.
Small sealed lasers can run the risk of suffering serious damage to
the cavity if the emitted beam is back reflected directly into the laser.
(More common at approx. 250W pulsed and above). Therefore, if you intend
to process a material which is reflective at 10.6µm this device
should be considered. It must however be used in conjunction with a Polarising
mirror, (or phase retarder) further down the system. At powers exceeding
250W an additional cooling jacket may be required. 
This
device will allow the user to externally vary the power delivered from
the Laser. Many lasers only vary their output power by pulsing full
power on and off, and this does not always provide the fine control
needed for some materials. This device will give infinitely variable
control of the transmitted beam from approx. 6% to 100%.
A
rotary adjustment which provides fine focus control of the lens & nozzle
assembly. Although maintaining the compact size of the family, its
notched adjustment ring provides easy handling, and the clear engraving
allows the user to measure the ±10mm focus range in 0.1mm increments. 
Three different focal lengths are available as standard. These are
38, 63, and 100mm. The lens is mounted in a separate cell, which allows
for easy removal and cleaning of both surfaces. Adjustment of the nozzle
standoff is independent giving a total of ±3mm. The gas inlet
is via a standard a 6/4 pipe 
Designed to provide easy alignment and low maintenance. Each mirror
block is supplied pre-aligned to a 45º angle of incidence to within ±1
arc minute. Therefore, many systems may not need alignment. Any adjustments
that are required can be carried out through the main block. This enables
the mirror to be removed, cleaned or replaced without losing alignment.
This unit can be used to externally switch the beam on and off by
directing it into an internally mounted beam dump. A mirror is actuated
by a rotary solenoid, the beam 'on' position being denoted by an indicator
lamp. Power is supplied and the shutter triggered via a 6-way multi
pin plug.
This uses a low power laser diode to inject a visible beam into the
system. It can be used as an aid for system alignment or spot alignment
of the focused beam (note: the visible beam first has to be aligned
co-axial to the CO2 laser beam).
As supplied will provide a visible exit beam on axis, but small adjustments
may be required to align with the CO2 beam.
The centring cell allows the lateral position and orientation of the
lens nozzle unit to be adjusted.
