摘要: Several approaches have been demonstrated to build focus tunable lenses. The additional degree of freedom enables the design elegant, compact optical systems, typically with less mechanics. We present a new range electrically and mechanically lenses different sizes and tuning ranges discuss their characteristics. show how tunable can be used improve design for auto-focus zoom in terms size, quality speed. Furthermore, we an LED-based spot light variable illumination angle, which shows optimal performance in terms efficiency.
