ABSTRACT:
A micropipette puller of the type having a laser for heating a length of capillary to be pulled is shown. Before intercepting the capillary, the laser beam is first passed through an aperture to reduce the beam width to a desired size. In one embodiment the aperture is made by a pair of movable shutters allowing the beam width to be adjusted. In this embodiment the spacing between the shutters can be made small in relation to the length of capillary to be heated and the resulting slit scanned back and forth along the capillary. Fixed, removable aperture plates means are also shown.
