FAQ
Q: What is the licensing requirement for laser?
A: Licences are required to manufacture, sell, possess, use, import and export a Class 3b or Class 4 laser apparatus. Moreover, these licences are also required for laser systems embedded with Class 3b or Class 4 lasers.
Q: What is laser classification?
A: The classification of a laser product provides information on the degree of laser hazard of the product. The higher the class, the more powerful the laser and the greater will be its potential to pose serious danger if used improperly.
Q: How long does the Laser Diode (LD) last?
A: The LD lasts for approximately 50,000 hours at 40°C with failure rate of 10%.
It lasts for approximately 100,000 hours at normal temperature (Approx. 25°C).
