Compared with traditional light field control, vortex Waveplate has the advantages of high efficiency, stability, simple operation and specialized function. Its true zero-order characteristic significantly reduces Wavelength sensitivity, improves temperature stability and expands Incident Angle tolerance. The device has been widely used in the fields of Quantum Optics, light field control, atmospheric Optical Communication, super-resolution microscopic imaging, optical tweezers and precision Laser processing. The spiral Phase plate directly introduces a Phase delay through a physical thickness gradient structure (such as a spiral step), which converts the Gaussian Beam into an annular beam distribution with zero central intensity. The surface of this Optics element consists entirely of spiral Phase steps, which are intended to modulate the Phase properties of the Transmission beam.

Product overview

A spiral Phase plate is a Optics element that enables an incident beam to produce a spiral Phase distribution. It imposes a Phase modulation on the beam in a linear relationship with the azimuth angle, so that the wave front is a spiral structure, forming a vortex beam with orbital angular momentum, which is commonly made of transparent materials and used in Optics manipulation and other fields.

|High threshold vortex Waveplate (& lambda;/2 & & lambda;/4)

Product overview

Vortex Waveplate (S-Waveplate) has polarization-dependent Optics characteristics. Depending on the Polarization State of the incident beam, it can be used to generate a vortex beam with a spiral Phase wavefront, which can convert the TEM00 mode Gaussian Beam into a "hollow hole" Laguerre-Gaussian intensity distribution. In contrast to helical Phase plates, vortices are Waveplate polarization dependent, carry polarization information, and generate a vectored polarized beam.

Main application scenarios

·Laser precision machining

·Vector Polarization and Vortex Light Generation (M/2 Vortex Waveplate): Angular polarized light is generated when linearly polarized light is incident on the vertical fast axis. The size of the central dark spot after focusing is small. It is suitable for high-width-depth ratio micro-hole processing (such as semiconductor wafer drilling) to reduce edge thermal damage. Radial polarized light is generated when linearly polarized light is incident on the horizontal fast axis. Longitudinal field can be generated after tight focusing, which is suitable for ultra-Diffraction Limit micro-hole processing, when the Circular Polarization is incident, a vortex beam carrying OAM can be generated, and the energy distribution of the annular spot is uniform.

·Vector polarized light generation (M/4 vortex Waveplate): when the incident light is left-handed/right-handed Circular Polarization light, radial/angular polarized vector light can be emitted respectively. compared with the X/2 vortex Waveplate, the vector light beam generated by the device is still Gaussian-like spot and will not form a central "hollow hole" intensity distribution.
