The CO2 Surgical Laser machine(Model:CL40) with CE$ISO( Laser power to tissue : 25W/30W) 1).Therapy Principle: The angle of radiation of CO2 laser is very small and its energy density is high. Output power density will reach several kilowatts per square cm. if it is focused. So the boiloff and cautery of focus tissue can be used in the therapy. Also if it isn't focused, the laser radiating focus tissue can bring about concretion effect. CO2 laser surgical system outputs infrared rays which wavelength is 10600nm . Its penetrability is comparative large. Because it can incise focus tissue after focusing, CO2 laser surgical system is also considered as laser scalpel. If beam of laser is enlarged, it is good for the heating-up physical therapy of the deepest tissue. According to the output power, CO2 laser therapy instrument has three kind: great type, medium type and desktop type. 2).Specification: Laser wavelength:10600nm Continuous /Output power:>25W (>30W) Focal spot diameter:<0.5mm Operation mode:CW\single\Repeat pulse\super pulse Articulated arm:7-joint spring-balanced Working radius:110cm Aiming beam:Diode laser 635nm\2mW Aiming beam mode:CW \ Repeat pulse\sans Power supply:AC220V or 110V Packing size:400×200×900 (mm) Gross weight:45kg (Net weight 30kg) 3).Applications 1.
