Description
MID14-24 motorized mechanical diaphragm
The MID14-24 is precise motorized iris diaphragm, which is adjustable either mechanically or from PC via intuitive graphic user interface (GUI). Due to the unique design, a aluminum blades forming square diaphragm always remains centered about an internal SM1–threaded hole. Even while tuned from 0 to 14 mm size, the diaphragm always maintains the centricity of squared aperture to round external diaphragm. The blades are black to reduce unwanted reflections. The MID14-24 motorized iris diaphragm adjustment precision is ~10 µm per min step.
Square Iris diaphragm is also designed to be compatible for both Stand-alone (MID14-24) and 60mm standard (for example Thorlabs) Cage System (MID14-24C).
