How long does the laser last?

  • An expected usage time (= life time) of the laser is 10.000 hours. The life time doesn't decrease while you're not using the device.

What type of laser is used in Mr Beam II?

  • Mr Beam II (dreamcut / dreamcut [S]) uses a blue semiconductor laser (a laser diode).

Which wavelength does the laser have?

  • The laser has a wavelength of 450nm. Therefore it is blue, visible light.

What is a beam divergence when cutting? 

  • Mr Beam II & II dreamcut: The beam exits the diode with a diameter of 1.8mm and is focused to the spot 90mm afterwards. This means the focus angle is really sharp so that there is almost no difference between entry and exit of a cut.
  • Mr Beam II dreamcut [S]: The beam exits the diode with a diameter of 0.8mm and is focused to the spot 40mm afterwards. This means the focus angle is really sharp so that there is almost no difference between entry and exit of a cut.

What is the spot size on surface?

  • Mr Beam II & II dreamcut: The spot size is 0.2mm.
  • Mr Beam II dreamcut [S]:  The spot size is 0.15mm.
