Details

The e-TransFlector™, an electrically switchable transreflective mirror that was developed by Kent Optronics, represents a unique state-of-the-art of electro-optically switchable mirror. It is a solid-state thin film device made from a special liquid crystal material, which can be rapidly switched between pure reflection, half-reflection and total transparent states through a push button. The e-TransFlector™ series products offer customers a switchable reflective shutter for both visible and infrared applications, while at the same time provide the flexibility to customize bandwidth, aperture size, and array format, as well as an excellent environment stability.



The e-TransFlector™ products can be used either as a component in customer system or a standalone device for designated purposes. Examples include switchable polarizer, achromatic polarizing switchable beam splitter/combiner, light shutter, laser beam director, switchable mirror and half-mirror, switchable energy saving windows/glazing, smart spectacles/sun glasses, etc… The envisioned systems and applications include projection displays, helmet mounted displays (HMD), laser protection devices, see-through displays, cameras/camera-phones, vision-aid devices, and high-throughput, spectrally tunable filters, to name a few. The e-TransFlector™ is superior to the current state-of-the-art switchable mirror products: it has ~87% photopic reflectance in the reflection state, >87% photopic transmittance in the transparent state, and ~43% reflectance/transmittance when in the half-reflection state. Its reflection bandwidth can be tailored from 50 to 1,000 nm and the state-to-state transition time is nominally 10 - 100 milliseconds.

It comes with a compact power supply that can be either battery or 110/220 V wall-plug powered. Customers have the option to choose the e-TransFlector™ substrate material, shape, and curvature. All products are offered at a competitive price. A demo is available upon request.
