MAC 5000

Overview

The standard LEP lter wheel systems are based on a reliable stepper motor

drive technology. Each module can support two six position lter wheels, either

as two separate lter wheel units or a single dual lter wheel device. Additionally,

this module can operate up to three electronic shutters. Sophisticated interface

options allow for programmed electronic synchronization of the lter and shutter

operation. For example a gating signal can be generated when the lter wheel is in

position to trigger a camera or strobe.

I/O Connections

Two connectors are designated to connect to lter wheel 1 and 2. They are

similar with the exception of the shutter connections. Filter wheel 1 has connec-

tions for shutter 1 and 3, while lter wheel 2 has connections for 2 and 3.

The SYNC-OUT-IN mini-DIN connector supports the lter wheel sychroni-

zation control signals.
