Variable attenuator
Variable attenuator is a device used to reduce the laser power by taking advantage of its linear polarization. To use a combination of laser source alters its output power in a continuous manner without losing beam stability. You can choose 266nm, 355nm and 532nm and also ask customized order for specific wavelength from deep ultraviolet to infrared.
Applications
Laser processing machine, solar cell manufacturing and inspection system, semiconductor manufacturing and inspection system, LCD manufacturing and inspection system, etc.
