DATASHEET pi_ibm_65.pdf


The IBM 65 totally closing iris diaphragms are the motorized versions of the manual IB-D54 iris diaphragms.

Their advantage is that they can be used in inaccessible places or closed devices, as they can be remote-controlled.

The motorized iris diaphragms come in a housing compatible with the system SYS 65, this means that they have an optical height of 32.5 mm.

The different aperture sizes are regulated with either 2-phase step motor with gear or with DC servo motor with encoder and gear. To indicate the end positions (open or closed), they are equipped with two limit switches.

The IBM 65 totally closing iris diaphragms have two lamella sets in 3.1 mm distance.
