2. Characteristics and description
2.1 Working principle
The AO series is a focusing module which can be mounted in front of a fixed focal
length lens to rapidly change focus.
The AO series allows the user to refocus the lens faster than moving the lens
mechanically with traditional motorized solutions.
The built-in driver has been specifically developed to accurately control the piezoelectric
elements.
A demo user interface with basic control functions is available via a web browser
interface. The lens can also be fully controlled with a dedicated .dll library,
downloadable from the Opto Engineering® website. The library includes an autofocus
algorithm and a calibration tool to help users integrate the AO module into their
product or application.
There are two versions of the adaptive lens. Version A has positive optical power and
version B has negative optical power. The positive lens can change the best focus plane
from far to close while the focusing power moves from zero to the maximum power.
The negative lens can change the best focus plane from close to far while the focusing
power moves from zero to the maximum power.
