The following instructions describe exchanging light tube assembly in the Cypher AFM. The light tube
can be exchanged without disassembly through the front of the instrument with a little familiarity of the
process. For the reason of clarity the instructions describe exchanging the light tube by disassembling
the enclosure followed by the process done through the front of the instrument.
18.1. Types of Light Tubes and How to Identify Them
The Cypher can be equipped with interchangeable light sources. Some of the nomenclature:
Laser Diodes: Best all around choice for AFM imaging. Lower noise for imaging techniques, but
with some interference effects which can lead to background oscillations when performing force curve
measurements.
