The microscope is comprised of five basic components: enclosure, chassis, backpack, scanner, and
camera. The enclosure, chassis, and backpack are common to all versions of the Cypher. The scan-
ner and camera are designed to be modular and easily interchanged by the user.

4.1.1 Enclosure
The primary function of the enclosure is to isolate the imaging portion of the microscope from
acoustic noise such as talking or music. Acoustic noise can cause the mechanical components hold-
ing the sample to move, thereby showing up as noise in the microscope images. The secondary
role of the enclosure is to provide a local environment for the microscope itself, in which the tem-
perature can be controlled. Keeping the microscope at a constant temperature is important for
maintaining long-term control of the relative position between the cantilever and the sample.
4.1.2 Chassis
The chassis is the central structural unit supporting the scanner, camera, and head. While the scan-
ner and camera are modular units designed to be interchanged by the user, the head is just a sub-
assembly of the chassis and is permanently attached to the chassis. The head is responsible for the
detection of the cantilever deflection and has integrated motors that allow the user to auto-
matically position the laser spot onto the cantilever.
The objective lens attached to the head has two important functions: it focuses the laser light onto
the cantilever and works with the camera to create an optical view of the sample.
4.1.3 Backpack
The backpack is located on the backside of the enclosure and houses a very powerful set of digital
and analog electronics that extend the functionality of the ARC2. Like the ARC2, the backpack has
