This tutorial provides a quick path to learning the basic operation of the Cypher ES Environmental
AFM. If you own the standard scanner, please follow the tutorial in Chapter 4 on page 17. The tutorial
contains a set of steps that will teach a new user with a basic understanding of AFM operation how to
obtain an AC mode topography image in air.
All new users should complete and understand this “AC Mode Imaging in Air” tutorial
before attempting any imaging.
The Cypher is a research grade instrument and improper use of the instrument can cause damage to the
instrument and/or injury to the user. This tutorial will take approximately 3 hours.
Before you start:
• We assume you understand the aspects of running this system safely: (
Chapter 20 on page 229.)
• You are familiar with the basic names of the hardware components and software controls (
Chap-
ter 1 on page 3
.)
• You have powered up the Cypher and launched the software: (
Chapter 2 on page 10.)
11.1. Required Materials
This tutorial is designed to be performed, not merely read. If possible, take the tutorial under the
supervision of an experienced user (tell them to mostly sit back though, or you will not learn as much
as you would by yourself).
It will be necessary to gather a few items prior to beginning the tutorial:
1. Cantilevers: You will need an AC160TS cantilever, which is manufactured by Olympus. The
AC160TS has a spring constant of ~42N/m and a resonance frequency of ~300kHz and is a
workhorse for AC mode imaging in air. Every Cypher ships with a package of AC160s, but
if these cantilevers are unavailable, any cantilever with a similar spring constant and resonance
frequency should work fine.
