What is the difference between a Class 3 and Class 4 laser?
So what’s the difference between class III and class IV lasers? The biggest difference is their maximum power output. The FDA defines a class IIIb laser as a device with a power output between 5-500mW (0.005-0.5W), and a class IV laser as a device with a power output above 500mW (0.5W).
How much does a Class 4 laser cost?
Class IV lasers are able to deliver up to 1,500 times more power than Class III lasers. As a result, they reduce treatment times and offer greater penetration. Class IV lasers range in price from $12,000 to $30,000.
Do Class 4 lasers require safety controls?
Whenever possible, class 4 laser should be controlled and monitored at a position as far as possible from the beam path to mitigate the risk and hazard. It may be necessary for the Laser Safety Officer (LSO) to measure the lasers in order to establish the maximum permissible exposure (MPE) values.
What dangers do all open class 4 lasers pose?
Only class 4 lasers pose real fire safety concerns. Their direct beam as well as any types of reflections can ignite combustible materials. For a safe integration, those lasers must be enclosed properly and account for all possible angles of reflection, including diffuse reflections.
Is it safe to watch videos of lasers?
Watching the laser in person is a different story due to the radioactive light from the laser at the source. The only problem might be that your camera might get damaged or destroyed by the laser. But if you can get a good recording, it’s perfectly safe to watch it without eye protection.
What is a Class 3 laser pointer?
Class 3. Class 3 has two levels – Class 3R and Class 3B. 3R can cause damage to an eye although it is low risk and includes some more powerful laser pointers and DIY home products. Class 3B lasers can cause serious damage to eyes depending on the power and length of exposure.
