si mirrors for CO2 laser machines

SI mirrors 25 mm. with gold plating

The standard maintenance set contains 3 SI (silicon) mirrors with vapor-deposited gold layer for the highest possible reflection level. Optionally, you can also choose 5 mirrors. Machines with a 'flying' laser tube typically have 5 mirrors. Think especially of large machines from 250 x 130 cm. The mirrors are 25 mm in diameter and can usually be replaced very easily by loosening the locking ring or plastic screws behind the mirror. Because of micro pitting mirrors should be replaced at least once a year.

tip : never touch the front of the mirrors with your fingers. Your (invisible) fingerprint will burn directly into the mirror by the laser and scatter the light.

znse lens


In the set you will also find a very high quality zinc-selenium lens for focusing your laser beam into a very small intersection. Lenses should be replaced preventively at least once a year. This lens has a diameter of 1 mm. and a focus distance of 20 mm or 50.8 mm. Optionally you can choose a diameter of 63.5 mm with focus distance 25 mm. Larger machines in particular have lenses with a diameter of 63.5 mm.

The lens has a very delicate coating. Use the attached special paper towel to hold the lens on the sides.

chiller water tank 10 liters

Chiller water – 10 liter tank

Chiller water prevents damage to your CO2 laser, fiber laser or laser welding machine and any water-cooled system can be used. Immediately replace tap water with chiller water to avoid problems. Chiller water properties :

  • prevents algae growth in laser systems: Heating the cooling water creates an ideal breeding ground for algae growth and the multiplication of organic components in the cooling water. Chiller water is environmentally friendly and prevents organic algae growth and is bactericidal.
  • lubricates the system: the components in chiller water provide additional lubrication of cooling systems with tight tolerances. This creates less friction and less wear in the system.
  • better heat transport: chiller water has a much higher thermal transfer coefficient, which means that heat from laser sources is dissipated faster and more efficiently. This makes the system respond faster and prevents temperature peaks in the laser source.
  • protection against low temperatures: chiller water has a low freezing point, which means that laser systems are less likely to break down and that the system can start up and run smoothly even at lower temperatures.
  • safe and environmentally friendly: chiller water does not harm the environment, is non-toxic and can be used in all systems.
