Imina Robot Micro (miBot™)

Imina’s Micro robots are the most important components of their probing and manipulation solutions, designed for customers who wish to use them in an optical microscope environment, or in an SEM environment where the highest level resolution is not required. They are extremely compact mobile cubes of just over 2x2cm horizontally, and with a low height of just 12.5mm above the stage they are compatible even with short working distance microscope objectives and SEMs. They are fully mobile actuators with the freedom to move at different speeds over the stage on which they sit in X, Y and rotation. Additionally the probe arm is able to move independently in Z.
