Abstract
A method and an apparatus for laser microdissection of specimen regions ( ) of interest of a specimen ( ) are described. In a first step, an incomplete cut line ( ) enclosing the specimen region ( ) of interest is generated by means of a laser beam ( ). At the incomplete point of the cut line ( ), there remains a web ( ) which joins the specimen region ( ) of interest to the surrounding specimen ( ). In a second step, the web ( ) is severed with a single laser pulse directed onto it, thereby completing the cut line. The specimen region ( ) of interest is in that context detached from the specimen ( ) and falls by the action of gravity into a collection vessel ( ).
