1Introduction

The Gatan UltraScan™ family of cameras is designed to deliver the ultimate

quality in transmission electron microscope images. It is the first digital camera

system with the potential to replace film as a recording medium in the TEM.

New technology has been introduced at every stage of the imaging process to

improve resolution, sensitivity, dynamic range, linearity and speed of operation.

The UltraScan™ family shares a compact mechanical design for bottom mount

CCD (charged-coupled device) cameras with full retraction capability and

complete compatibility with GIF and ENFINA™ spectrometers.

The UltraScan™ family of cameras is available in two series, Reference and

Standard series. The common feature to these two series is the utilization of the

patented High-Contrast Resolution (HCR™) optical technology. HCR™

technology results in images with higher resolution and higher contrast than

images acquired with traditional optics and takes digital imaging resolution to a

level that challenges film. The Reference Series UltraScan™ cameras

incorporate the First Light™ readout electronics which reads out all four CCD

output channels in parallel for increased speed while maintaining low-noise

performance. The Standard Series UltraScan™ cameras read the CCD through

a single low-noise channel. The Reference series features 2k x 2k and 4k x 4k

CCD format and the Standard series features only the 4k x 4k format.

This user guide is written for the Reference series, Model 894 US1000 (2k x

2k) and Model 895 US4000 (4k x 4k).

The intent of this guide is to:

•Help the user become proficient with the Gatan DigitalMicrograph

software to correctly acquire images from the CCD camera.

•Give the user a brief understanding of the working principles of the

camera.

•Allow easy troubleshooting.

UltraScan User’s Guide Reference Series Rev 1.0 2-1

2Getting Started

The following steps will enable the first-time user to switch on the digital

camera, launch DigitalMicrograph and prepare for the acquisition of an image.

•Make sure that the viewing chamber is at the proper vacuum.

•Make sure the water and the three color-coded pressure lines are

correctly connected to the camera and proper water pressure is

maintained.

•Switch on the CCD camera controller (Fig. 2-1), the LED will turn

green.

•Flip the Shutter switch to AUTO.

•Flip the Peltier Cooler switch to the COOL position. For best results it

is recommended waiting (2 hours or more) for the system to stabilize.

•Turn the computer on (if it is not on yet) and double click on the

DigitalMicrograph icon to launch the application.

2.1 The Workplace

When DigitalMicrograph is launched, you will see the commonly used tools

(left side), the Image Acquisition and Saving tools (right side), and the Result

window as shown in Figure 2-1. These tools are composed by “floating”

windows fully stackable to allow customization.
