Liquid lensesdo havesomeadvantagesand disadvantagescompared to glass
optics:
lAdvantagesof liquid lenses
oExtremelyrobust to mechanical shock (best choicefor fast moving robotics)
and acceleration
oFastfocus(oftensignificantlyfaster than10 msunder commonconditions)
lDisadvantagesof liquid lenses
oLimited resolution
oHighchromaticaberration
oAnyacceleration(gravitational aswell asacceleration frommovement)
might increasespherical aberration aslong astheforceisworking (will dis-
appear if force hasceased within several 10ms)
3.2.3 Useof Canonlenses
Wearesupporting Canon EFlenses. TheSVCam-EFadapter givesyou thepossibility
to mountCanon EFlenseswith full control of focusand iris. Canon lensesarewell
known for their optical excellenceand combineperfectlyto highresolution machine
visioncameras.
