17.1. Overview
The Cypher AFM has an excellent optical system. A high quality microscope objective sits at the heart
of this system. It affords an excellent optical view of the sample but also guides laser beams for the
cantilever detection system.
A camera and white light source are embedded in the “view system” which protrudes from the top of
the cypher enclosure.
17.2. Microscope Objective
The objective is not user replaceable. The magnification is fixed. Only digital zooming is possible
within the software.
Depending on the imaging conditions (air, fluid) a correction collar on the objective must be adjusted.
The tutorials in this user guide will always indicate the correct setting. An overview of these various
settings is given in the table below.
