Technology Overview

The motorized tilting module rotates the objective, giving a higher level of freedom to reach the sample from different angles. The module also includes a Piezo objective positioner, ensuring additional movement of the objective in the Z direction.


Novel surgical methods utilizing grin lenses or miniature prisms allow optical investigation of deep structures within the brain. Implementing these technologies is greatly enhanced by our motorized tilting objective:

  • aligning optical axis of the embedded optical elements is facilitated by the handwheel operated multi-axis positioning of the grin lens/Smart microscope,
  • store and reuse optimal angles and positions when experimenting multiple times with the same animal,
  • utilize the units high-precision movements to fine adjust position and alignment without actually touching the assembly.


  • 180º rotation around the horizontal axis

  • 100º rotation around the vertical axis

  • speed of rotation: 4º/sec

  • unidirectional repeatability: less than 0.02 mrad (~2 µm)

  • Z movement with piezo objective positioner module: 400 µm

  • transmission over 80% (700-1100 or 900-1300 nm)

  • accepts both conventional and large back aperture objectives

  • green illumination module

  • maximum number of mounted detectors: 3


  • flexible objective positioning with high precision

  • highly stable in all positions

  • fast z-stack acquisition also from tilted position

  • close coupled detectors

  • useful for in vivo experiments, intravital imaging, and deep brain imaging in rodents or even non-human primates
