I don't know if it's me, but there was no light through the optics to see the mask/wafer to align.   I tried adjusting illumination and focus but I never could get the light to come on. It is like when the lamp is burnt out on the microscope & you can't see.  I asked another lab member to check it out, he couldn't get it to work eeither
