At the Iranian Light Source Facility (ILSF), two different storage ring options are being studied. The designs differ in emittance. In the first option the calculated emittance is 3.278 nm-rad whereas for the second option emittance is 0.937 nm-rad. In this paper the elec-tron beam emittance effects on the source radiation properties from bending magnet, wiggler and undulator, X-ray optics and the beamline design are carefully studied. The present calcu-lations demonstrate that in the case of 0.937 nm-rad brilliance of undulator is increased by a factor of about 5. For bending magnet, flux is reduced almost 1 order of magnitude for hard x-ray regime. Because of smaller size of the source for undulator at the case of 0.937 nm-rad, we can achieve to a smaller spot size and higher resolution with easier focusing systems and usual kind of monochromator than the emittance of 3.278 nm-rad and for the bending magnet hard x-ray beamline, size of the mirrors reduced 30
