Recently, I have posted two articles on autocollimators and on measuring very small angles. I also illustrated one of the applications of autocollimators when measuring the wobble of a translation stage.

Here, I would like to post an update on autocollimators applications and alignment procedures through a video which details all the necessary steps in the assembly. I will also try to make videos in a more systematic way when posting new articles such as to offer the theory in the text version of the article and the alignment tricks in the video.

I hope you will enjoy the video. Do not hesitate to comment on youtube to share your opinions, ask me questions or even suggest new topics that you would like to hear about!
