TOPAZ EZ HD at a Glance
The TOPAZ®EZ HD is an easy-to-use desktop video magnifier that provides
clear and sharp magnification of documents, newspapers, photos, and other
items. With simple to use controls, you can make quick magnification, color,
and brightness adjustments to best suit your vision needs.
The high-definition camera produces a clear picture with sharp images and
crisp text. This lets you use a lower magnification to maximize the amount of
information displayed on the screen. It also reduces the need to move the XY
table as much when reading text, looking at pictures, or working on crafts and
other projects.
The unit includes the following features:
Auto Focus, which creates the clearest view without any need to make
adjustments
16 magnification levels with a crisp, sharp image that lets you precisely
adjust text to the size you need
Four color modes; choose the one that is most comfortable for you
One-touch button to freeze images
Widescreen 20-inch or 24-inch LCD monitor
Adjust the height and angle of the monitor for the best view as well as
extra neck and upper back comfort when viewing the screen
Adjustable screen brightness
Two lights on either side of the camera provide object illumination, which
is diffused to prevent glare and reflections when viewing shiny
documents like magazines and photos
Large low-friction XY table moves a full 16 inches from left to right for
easy reading of even large-format documents
XY table’s braking mechanism lets you lock the table movement down
tight when you want it to hold steady
Working distance between XY table and camera: 8.25 inches / 21 cm
