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. |

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.
