Laser Polarization-State Switching Module Pol-trfm
The electrically controlled laser-polarization switching module rotates typical ultrafast-laser polarization by 90° with a half-wave plate, produces circular polarization with a quarter-wave plate, radial or azimuthal polarization with a radial polarizer, or a hollow beam with a vortex phase plate. Polarization control improves processing quality. Connecting or disconnecting RS232 pins6 and7 changes the input logic level, rotating an internal flip mount to switch optical-path position. Magnetic limit switches at both positions identify the mount's location.

Laser cutting is a precise, noncontact process widely used in advanced wafer-semiconductor manufacturing. A focused high-energy beam locally melts or vaporizes material through photothermal effects. Wavelength, power and pulse width are adjusted to material properties for optimal cuts. 晶沐光电 has its own laser-processing line with UV/ultrafast lasers, wafer infrared stealth-dicing and cleaving machines, infrared fiber cutting machines and other equipment for varied wafer-cutting needs.
