Upper Zoom Modules contain the core zoom lens optomechanics of your
Zoom 70XL. The specific Upper Zoom Module option you select will
determine the specific zoom function of your system.
 Manual Module – Provides basic hand-driven 7:1 zoom function.
Iris Diaphragm Module – Provides manual 7:1 zoom while also allowing
better illumination control. With Iris, you can increase depth-of-field
and/or maintain more consistent image brightness across your entire
field.
Detent Module – Obtain specific and repeatable magnification stops
throughout the 7:1 zoom range without the complexity and cost of
motorization. Detents are ideal for metrology applications where each
position can be calibrated.
Motorized Zoom Module – Provides remote and programmable automated
zoom. There are two types of motor options available... DC Motorized
Versions provide smooth continuous zoom throughout the entire 7:1 zoom
range providing you with maximum imaging flexibility.
Stepper Motor Versions provide zoom homing positions for applications
requiring repeatable magnification settings. Stepper Motor Modules have
a companion RS232 controller that may be purchased as a self-contained
unit or as an OEM Board for
customized integration. All Stepper Motorized Models come complete with programmable homing sensors.
