Abstract :
A tunable hyperchromatic system for confocal imaging is presented. The system, consisting of a magnetically-actuated, hydraulically-tunable concave membrane lens in combination with a positive diffractive lens, functions as a tunable filter in the 450 - 900nm spectral range. A spectral width of 15nm is demonstrated over the entire spectral range.
