The Basic Principles of Laser Microdissection

Principles of laser guidance and laser adjustment for perfect cutting results

July 24, 2014

Laser Microdissection (LMD) is a technique for isolating specific and pure targets from microscopic heterogeneous samples for downstream analysis (DNA, RNA & proteins); based on microscopic imaging and utilizing a laser.

In contrast to other systems which use a fixed laserfocus for dissection, Leica Microsystems' LMD systems guide the laserfocus for dissection. This unique feature allows highly precise laser dissection independent of the stage accuracy.

This tutorial describes the basic principles of the laser guidance and how the laser can be adjusted for perfect cutting results.
