Alpha Micron / AKARI LCF Liquid Crystal Technology performing light control system. Alpha Micron’s liquid crystal technology called e-Tint® allow you to switch between a transparent or darkened state with no loss in visual integrity at the simple push of a button. With e-Tint®, size, shape, color, and level of tint color can be customized to meet various performance needs.

Alpha Micron’s liquid crystal-based light reactive technologies have found a natural home in the automotive industry like below:
• New LC-based rearview mirrors that transform into a display.
• See-through displays adapted to be visible in all lighting conditions.
• Electronically controlled all-glass roofs, providing openness while blocking direct sunlight as needed.
• Windshields that adjust to lighting conditions or driver privacy preferences.
• Films that enable changing interior themes
They have created the first-ever battle-field ready electronically controllable eyewear – now approved for the Army’s Authorized Protective Eyewear List (APEL). Ballistic lens combined with Electronic Tint-on-Demand™ technology, designed to enhance tactical capability and provide protection by enabling automatic switching when lighting conditions shift (for example, moving from the outdoor sunshine into a dark building). By switching automatically, soldiers are not required to remove their sunglasses, and their eyes remain protected at all times. Created by Alpha Micron in response to Army’s need for Transitional Combat Eyewear Protection (TCEP), this first-ever electronically controllable eyewear is now in production and can be purchased
A new generation of ultra-fast light-reactive eyewear currently in testing; this innovation will provide active eye protection against laser and intense flashlight (including IR radiation), with our signature ultrafast (faster than 0.01 sec) switching time.
Akari Liquid Crystal Light Control Film utilizes dichroic dye and liquid crystal to instantaneously change the contrast of the film with controls permeating light via the switching of an electrical charge.
In their light absorptive electronic shade systems, a dichroic guest dye is added to the liquid crystal host. The dichroism of the dye results in an absorbance that is orientation dependent. These dyes are specifically designed and fabricated to have a tight alignment with the liquid crystal host. Therefore, reorientation of the host by an applied field results in a reorientation of the dye and a subsequent change in the absorbance of the system. In effect, the system behaves as a molecular version of a blind. Non-polarizer-based systems have advantages over conventional polarizer-based systems in that they offer the opportunity to shift the transmission window as needed. For example, for eyewear applications, the mixture can achieve clear state transmissions of > 70% which is not achievable by polarizer-based systems.
