LT-4LDS-V2 is a professional cutting module designed for long-term safe cutting and fine engraving processing. It is the most powerful 20W optical power blue laser head on the market today. Compared to V1, V2 is much improved with a new housing design, easier to use air assist, longer focal length, and more stable cutting output power.It can cut 10mm plywood cleanly in one pass at 3mm/s and can easily create the desired pattern on the wood. If you spend most of your work time cutting, choose LT-4LDS-V2 which will be your good companion.

—20W Optical Power Output With Air Assist

  1. 4-Beam compressed technology, 20W ultra-strong optical power laser module.

  2. Built-in fan cooling system, effective cooling to extend the service life.
  3. Air assistance performance update;change the diameter of air tube from M5 to M8, to get stronger air pressure at air nozzle。

  4. Newly upgraded protective window design, effective filtering of blue light
  5. Compatible with various engraving machines on the market (consult customer service if you are not sure)
  6. High stable 2EDG3.81 connector, up to 7A operating current
  7. Only 300~400 mw power decrease with 100% power output in 30 mins
  8. Support digital(TTL/PWM)and analog modulation

Optical Solution  

With four built-in 5W beam compression laser diodes and an optical output of up to 20W, this is the world's most powerful diode laser module.

Better Performance With Air Assist  

Air assist prevents fumes from sticking to the laser lens, which results in cleaner cutting edges, more accurate cuts and helps to extend the life of the laser cutting machine.

High Precision Engraved  

Use innovative compression technology to make the light spot smaller and more powerful, allowing you to engrave to the perfect level of detail within reach.

New Protective Cover Design  

The new laser filter has a single-sided viewable window design. It not only prevents blue light from stinging your eyes, but also allows you and people around you to watch laser engraving without goggles in the reserved window.

Excellent Heat Dissipation Design  

The built-in fan cooling system maintains a stable light output power during operation, dissipates heat effectively and extends service life.

Super Cutting Ability  

Cut through 10mm bass plywood by one pass

Cut through 20mm pine plywood by 2 passes

Cut through 8mm black acrylic by one pass
