    From the Car to the Surveillance Camera

    Microsystems Inc. introduces the world’s first self-cleaning glass module for camera lenses
    DFG consists of a hydrophobic layer, a dielectric layer, a patterned transparent electrode, and a cover glass added in front of a camera lens.

    The Drop Free Glass (DFG) Module, introduced at CES 2022 by Korean company Microsystems Inc., is yet another technology developed for the autonomous vehicle industry that may be applied to the security camera, action camera, and drone camera markets. The technology can even be applied to an entire pane of glass.

    DFG can promptly and efficiently remove various contaminants such as rainwater, fog, frost and dust generated on the surface of a camera lens using a unique microfluidic technology. It is a simple product structure applied to any type of glass application.

    The ultra-thin DFG can quickly and efficiently remove contamination such as rainwater, fogging, frost and dust on its surface using electrowetting technology.

    The DFG can be easily added to the design of most standalone IP cameras, multi-sensor 360-degree IP cameras, action cameras and multi-sensor drone cameras.

    DFG consists of a hydrophobic layer, a dielectric layer, a patterned transparent electrode, and a cover glass added in front of a camera lens. Raindrops start to form on a camera lens, in a spherical structure due to the surface tension of water, creating the effect of many unwanted tiny lenses that cause the primary image to be rendered out of focus and darker. Smaller raindrops have a greater surface tension than larger drops exacerbating the image distortion.

    When used on outdoor surveillance cameras, DFG can have a dramatic effect on visibility.

    The DFG-Aided Surveillance Camera can automatically or manually activate the DFG layer on detection of this distortion, consumes practically no current, and works quickly to remove the surface contaminants.
