Laser Details

Its the 30 Watt RF excited CO2 Laser made by Synrad. The exact model we have on the laser is the J48-S2 tube which has date code of September 2005. The laser is still running strong at 28.7 watts when measured with my PW250 - Laser Power Wizard.

Mirrors

The mirrors are as follows.

• x1 - 25mm diameter silicon mirror
• x2 - 20mm diameter silicon mirror
• x1 - 19mm diameter ZnSe with 50.8mm or 2" focal length

Mirror selection is critical for ensuring that you are receiving the maxium output power of the laser tube. The laser will have significant power loss. It is highly recommended that you utlize Si mirrors which are silicon glass gold plated mirrors and treat them as yearly consumables.
