**PLEASE NOTE** Uniblitz AI25 cannot be connected directly to a PC, this unit requires the AIC10 Iris Controller or Customer Created Driver solution; see Direct Control documentation for further details.

The Uniblitz AI25 is a motorized iris diaphragm (auto iris) that allows for the remote control of a variable 25 mm aperture. This electronically-controlled aperture is ideal for remote light attenuation or depth-of-field control. The iris’s aperture closes down to 1.5 mm, and an optional shutter attachment allows users to fully close the aperture.

The AI25’s low-profile form-factor means that it can be used in applications where spacial limitations are a consideration. An optional housing is available which gives the AI25 a compact package with no externally protruding components and two flat mounting surfaces.

Shutter Timing (when equipped)


The question regarding enhancement of shutter speed with the application of user supplied lubricants has been repeatedly asked. It is our experience that lubricating the shutter blades will actually slow the shutter down and eventually render the shutter inoperable. Under no circumstances should any type of lubricant be applied to the shutter blade area.
