Description
MID14C Motorized Mechanical Diaphragm
The MID14C 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 MID14C motorized iris diaphragm adjustment precision is ~10 µm per min step.
Square Iris diaphragm is also designed to be compatible with 60mm standard (for example Thorlabs) Cage System.
MID14C Diaphragm Features
