CO2 Laser Tube and Optics

A CO2 laser tube is the sealed glass tube that produces the infrared beam in a CO2 laser engraver or cutter. It works with a matching laser tube power supply, three mirrors and a focus lens. TriQuench India supplies CO2 laser cutting tubes and can advise on tube, lens and mirror replacement.

Choosing a CO2 laser tube: 80W, 100W, 150W

CO2 laser tubes are chosen by power and length. An 80W CO2 laser tube suits engraving and thin acrylic and wood; a 100W CO2 laser tube is the common choice for cutting 6 to 10 mm acrylic and MDF; a 150W CO2 laser tube suits thicker material and faster production. The tube must match the laser tube power supply rating and fit the machine's tube holders. For CO2 laser tube replacement, measure the old tube's length and diameter and note its power. RECI laser tube is a well-known brand on Indian machines; send the old model for a like-for-like quote. CO2 laser tube price in India depends on power, brand and length.

CO2 Laser Tube: frequently asked questions

How long does a CO2 laser tube last?

Glass CO2 laser tubes are typically rated from about 1,500 to 10,000 working hours, depending on brand, power and how hard they are driven. Running below about 80 percent of maximum current, keeping cooling water cool and clean, and avoiding frequent full-power firing all extend tube life.

How do I align CO2 laser mirrors?

Align one mirror at a time, starting at the tube. Put masking tape on mirror 1, pulse the laser at low power and adjust the tube so the spot is centred; repeat at mirror 2 with the gantry near and far, then mirror 3 at all four corners of the bed. The spot must land in the same place at every position.

When should I replace a CO2 laser lens or mirror?

Clean the CO2 laser lens and CO2 laser mirror regularly with lens tissue and alcohol. Replace them when coatings are burnt, pitted or cloudy, or when cutting power drops even after alignment and cleaning. A damaged lens can crack under the beam.
