The tool every optical lab needs to have

This video describes how to build a powerful alignment and metrology tool for your optical lab. It provides an accurate reference of infinity (collimated) light and allows to measure very small angles of reflective or semi-reflective (e.g. air-glass) interfaces. Autocollimators are real time-savers in optical labs!

If you would like to have more information on autocollimators and angle measurement, please consult these two posts on our website:

I hope you will enjoy the video! Do not hesitate to comment!
