CCD vs CMOS CCD and CMOS are both image sensors. They can be found in any device that creates an image. Cameras, webcams, mobile phones. They are one of the most common consumer electronics in world. For many years there has been a debate about which image sensor: CCD or CMOS. Let’s just make clear […]

Powering advanced optical design with liquid lenses

liquid lenses

Liquid lenses, are a type of optical lens that have a tunable focal length by shaping a liquid electronically. These lenses can be based on voice coil actuation, or based on electrowetting technology, which involves manipulating the surface tension of a conductive liquid droplet by applying an electric field. The core component of an electrowetting-based […]
