The moving part-free, new optical system has overcome the problem of motor durability, which had been one of the disadvantages of a laser scanning method.
The GaN (gallium nitride) LED used for the light source achieved high reliability with no light source deterioration caused by electrical noise.
A device containing moving part requires complete disassembly and readjustment during an overhaul. If laser elements have deteriorated due to electrical noise, they must be disassembled and reassembled.
