Point spread function (PSF) - confocal


PSFs were measured for the listed laser lines and appropriate band pass filter setups on Apo TIRF 60x N.A. 1.49 objective, pinhole size 30 nm. PSpeck (175nm) fluorescent beads acquired from Invitrogen Molecular Probes were mounted into the Immu-Mount mounting medium Shandon for measurement purposes.
Attached images represent 5 accumulated individual beads, accumulation was performed in Huygens Professional software.

Point spread function (PSF) - wide-field


PSFs were measured for the listed band pass filter setups on TE 2000 inverted microscope equipped with Apo TIRF 60x N.A. 1.49 objective and Vosskuhler CCD-1300 camera. PSpeck (175nm) fluorescent beads acquired from Invitrogen Molecular Probes were mounted into the Immu-Mount mounting medium Shandon for measurement purposes. Attached images represent at least 5 accumulated individual beads, accumulation was performed in Huygens Professional software.
