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.

Laser Mounts |  CO2mpact Laser Mounts
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.

C–LM (Standard) : Dia = 100, L = 15
C–LMA (Adjustable) : Dia = 100, L = 23
 
 

 
Pipe Supports |  CO2mpact Beam Pipes and Supports

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.
C-PSXX : H = XX, W = 95, L = 16
 
 
 

 
Beam Pipes |  CO2mpact Beam Pipes and Supports

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.
C-BPXX : Dia = 31, L = XX
C-BPE85/125 : Dia = 31, L = 85-125
 
 

 
Convertor Rings |  CO2mpact Beam Pipes and Supports

These will be required if several components are coupled together and need to be locked in a certain orientation.
C-CR : Dia = 31, L=22
 
 

 
Beam Expanders |  CO2mpact Beam Expanders
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.
C-BE1.3 (x1.3) : Dia = 42, L= 70 +5/-4
C-BE1.5 (x1.5) : Dia = 42, L= 70 +5/-4
C-BE1.6 (x1.6) : Dia = 42, L= 70 +5/-4
C-BE2.0 (x2.0) : Dia = 42, L= 70 +5/-4
C-BE2.5 (x2.5) : Dia = 42, L= 70 +5/-4
C-BE3.0 (x3.0) : Dia = 42, L= 70 +5/-4
C-BE3.5 (x3.5) : Dia = 42, L= 70 +5/-4
C-BE4.0 (x4.0) : Dia = 42, L= 70 +5/-4
C-BE5.0 (x5.0) : Dia = 42, L= 70 +5/-4
C-BE6.0 (x6.6) : Dia = 42, L= 70 +5/-4
C-BE7.0 (x7.0) : Dia = 42, L= 70 +5/-4
Other magnifications are available upon request.
 

 
Reflection Isolators |  CO2mpact Reflection Isolator
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.
C-RI : Dia = 55, L = 115
 
 

 
Manual Attenuator |  CO2mpact Manual Attenuator
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%.
C-MA : Dia = 55, L = 120
 
 

 
Fine Focus Adjustment |  CO2mpact Fine Focus Adjustment
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.
C-FA : Dia = 44, L = 130 ±10

 
 

 
Lens Nozzles Assemblies |  CO2mpact Lens Nozzle Assembly
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
C-LN38 (38 FL) : Dia = 38, L = 60
C-LN63 (63 FL) : Dia = 31, L = 86.1
C-LN100 (100 FL) : Dia = 31, L = 123.9
 
 

 
Mirror Blocks |  CO2mpact Mirror Blocks
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.
C-CM : H = 45, W = 38, L = 45

 
 

 
Shutter Unit |  CO2mpact Shutter Unit
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.
C-SU : H = 100, W = 90, L = 100

 
 

 
Injector Unit |  CO2mpact Beam Injector
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.
C-BI : H = 90, W = 85, L = 110
 
 

 
Centering Cell
The centring cell allows the lateral position and orientation of the lens nozzle unit to be adjusted.
C-CC : Dia = 60, L = 28
