ThetaStation is an opto-mechanical tool designed to perform spatial selective light delivery with OptogeniX Lambda fibers.

ThetaStation allows to confine and manually scan the light emitted by a Lambda fiber at sub-sites of its active length. By doing so, sub-portion of the tissue region where the Lambda fiber is implanted can be independently probed: this capability gives access to an additional degree of freedom during optogenetics experiments, which has particular relevance when readout techniques extending along one axis are used simultaneously with the site-selective light delivery (e.g. linear microelectrode array).

N.B.: This feature can also be employed to correct for implantation errors or uncertainty (Ref. Nature Communications).

General recommendations:

• Use of a Laser source and a Single Mode (SM) input patch cord is recommended for best transmission efficiency.
