The following sections describe typical workflows. For each workflow, we describe how to achieve
your outcome by building on the tutorials earlier in this guide.
30.1 Loading the cantilever and sample on a standard scanner
This tutorial is designed to be performed, not merely read. You will learn the most if you operate
the instrument yourself, with an experienced user watching and providing advice.
Note: If you own the environmental scanner, please follow the tutorial in Loading the cantilever
and sample on an environmental scanner on page 205 .
This tutorial covers sample and cantilever loading as well as the coarse approach of the cantilever
tip toward the sample. It is designed for a Cypher SPM equipped with the standard scanner and a
standard spot SLD or laser module (see
Types of light tube and how to identify them on page 114 ).
You need the following items to perform the tutorial:
Cantilever You will need an AC160TS cantilever, which is manufactured by Olympus. The
AC160TS, with a spring constant of ~42 N/m and a resonance frequency of ~300
kHz, is a workhorse for AC mode imaging in air. Every Cypher SPM ships with a
package of AC160s. If these cantilevers are unavailable, any cantilever with a sim-
ilar spring constant and resonance frequency should work fine.
Sample The tutorial uses the Asylum Research calibration grating that ships with every sys-
tem (part# 290.237).
Tools Part# 290.102: Tweezers with curved tips.
Part# 290.139: 1/16” ball head wrench.
