Pattern Illumination Device

The µ-MATRIX is a computer controlled illumination device which uses a DLP chip to create different patterns or projects images onto the sample in the field of view of the microscope.
In combination with wide field, spinning disk confocal or laser scanning microscopy methods, the µ-MATRIX is a powerful tool in the study of fast biological response signals. While performing similar functions as its scanner based sister devices, the µ-MATRIX enables the light induced events to occur simultaneously at multiple locations, eliminating the delay introduced by the scanning process.
The µ-MATRIX system consists of the optical module, the coupling to the microscope, the controller and the software. The optical module is coupled to the microscope without interfering with other existing devices (i.e. spinning disk, LSM, etc.).

Running Modes
  • Picture mode: series of pictures are preloaded and projected onto the field of view at fixed, user-selected frame rate
  • Sequence Mode: a preprogrammed sequence of points and/or ROIs is run a single or multiple times with timelines set by the user. Sequence elements located in the same timeline are displayed sequntially. Sequnce elements located in different timelines can be displayed either sequentially or simultaneously. Unlimited number of timelines.
