BARRINGTON, N.J., March 12, 2015 — The new Dynamic Focus VZM Lenses from Edmund Optics use an internal liquid lens to seamlessly adjust focus over a 7× range, from 0.65× to 4.6×. At the same time, the lens maintains the zoom capabilities of the standard VZM Zoom Imaging Lenses. Dynamic Focus VZM Lenses are suited for a range of applications including microscopy and circuit board inspection. The lenses feature a lockable iris, zoom control and a rotatable mount for optimal camera orientation. The internal liquid lens is controlled via 6-pin HIROSE connector and USB port. Coarse magnification adjustments can be made manually. The lenses include software, allowing them to be programmed to cycle through focus with a square, sinusoidal or sawtooth waveform or adjustable frequency and focus-shift range.
