Overview
The active liquid crystal grating achieves flexible adjustment of diffraction efficiency under the control of an external AC voltage (DC voltage cannot be applied externally). Model LCCPG03-70-0808 is supplied with a 3μm box thickness and a 70μm grating period over a clear aperture of 8mm*8mm; the cell thickness and grating period can be customized flexibly.
Applications
- Electrically tunable diffractive beam steering
- Programmable beam splitting and fan-out generation
- Wavefront shaping and adaptive diffraction
- Dynamic phase-grating and structured-illumination experiments
- Reconfigurable diffractive optics
Construction & Performance
- Diffraction efficiency >90%
- Clear aperture 8mm*8mm; element size 10mm*15 mm
- Box thickness 3μm, tolerance ±10%, uniformity 5%
- Glass material K9/ITO; ITO sheet resistance 350-400Ω/square
- Flatness (@633nm) λ/4
- AR coating 500-1700nm optional
Storage & Handling
Drive the device with an external AC voltage only; DC voltage must not be applied.
