Warning Warning: This page has not been released yet.

The Olympus OLS 4000 LEXT is a laser confocal microscope that can take high resolution 3D images by acquiring successive images of the sample between two heights. It then recombines the laser acquired images and the color images to produce a 3D projection that can be measured. It can measure dimensions, roughness, area, volumes, etc. Its specially developed lenses produce high quality images of the sample. The z axis resolution is 10 nm and the x-y resolution is 120 nm.
