The LEXT allows you to take height measurements of features too small to reach with a physical Stylus needle, in a non-contact mode that is much faster than engaging an AFM tip. In addition, very large aspect-ratios can be measured - for example, 1mm depth x 50µm width. Confocal microscopy ensures that only surfaces that are in-focus will return a signal to the microscope detector. The LEXT sweeps the focus motor and captures a 2D scan of your sample at each focus step, taken with a blue laser (405 nm). After the scan, the height of each surface is calculated by the focus step which produced the highest laser intensity, and this is constructed into a 3D image by the OLS software. |

|||
Because this is an optical method, films that are optically transparent to blue light and/or have transparent sloping sidewalls can produce non-physical measurements due to optical interference on the sample. In addition, features on the order of the laser wavelength can produce unreliable/non-physical data - for example, the data near (within ~500 nm) very steep slopes, or features ≤ 1.0 µm wide may not be reliable. |
|||

Surfaces that are opaque to the laser wavelength work best, although measurements on rectangular transparent edges do work relatively well. Edges of steps where light does not reflect in an ideal manner often produce non-physical features, typically manifesting as trenches/spikes right next to the sidewall. |

About
The Olympus DSX1000 is a high-resolution digital microscope with full electronic control, multiple imaging modes and sophisticated analysis software built-in.
The built-in optical magnification allows for high-resolution imaging without changing objectives. The system has applies Digital image stabilization and software image enhancement.
Users must be very careful to avoid crashing the 50x objective, because it does not rotate out of the way like our other microscopes.
