TopoMetrix Explorer - Replacement Controller and Repair Service


The safest way of getting an older tool running again is to test the whole unit - microscope head with electronics. This is why we prefer that you ship us your Explorer head (which is small) so that we can test what might be necessary to do to bring it back to full performance. We offer repair on almost all parts (laser, scanner, linearization, illumination), however, things might be broken up to a costly level. If you order a controller, we do all the repair on list prices.
A new PC. A new controller. New software. Repaired scanners or heads - fully tested. Scaled and linearized with the new software. A description of all connectors and how to handle the system. AND, if you wish, a re-installation service in your lab.
The TopoMetrix Explorer head has a unique mechanical design never matched by any other tool. Due to the full access from the bottom, the head can practically scan on any surface anywhere. Also, it enables a very special range of experiments: combine an AFM with ellisometry or use your temperature control for the sample.
Moreover, this Explorer controller improves the performance of your beloved tool. Scaner operate much more linear with our software. The small video screen is not required anymore - you can have that on your PC screen. Approach can be done with joystick. The LED illumination is much brighter and adjustable from the software surface. In conculsion - we are sure, you'll like these impovements.
