Motorized Iris Diaphragm 8MID98-4-90 is designed around iris diaphragm 10IBS130-98-4-N/H. It is a customer inspired design and is manufactured on request. As an upgrade to 8MID98-4-90 we developed model 8MID70-130 which is available from stock and can accept various iris diaphragm sizes as listed on its webpage.

For driving motorized iris diaphragms we recommend using Standa stepper motor controllers. Controllers of other manufacturers can also be used.
