 +These are the lab notes for the STM.  See the [[projects:stm:start|STM Project Page]] for an overview of the project.
  
 +> //This page is a lab notebook. It documents the work done in the lab and our thoughts, theories, and findings related to it. Everything you read here is work in progress and not final results. We believe it is best to have our lab notes out in the open, because it gives more detailed insight into what worked for us and what didn't. Of course you can also use this page to follow our progress!//

 +Currently, work is focused on setting up a precise interferometer which we can use to characterize movement of the STM stage.

 +Progress is documented here: [[projects:optics:log|Lab Notes for Optics Experiments]]
