The UGA‑42 Geo is another member of the UGA‑42 series of laser scanner devices for localized photomanipulation. In contrast to the UGA‑42 Firefly, the UGA‑42 Geo is mainly designed to generate illuminated regions of different size and shape in the field of view of the microscope. These selected regions can be rapidly moved with the galvanometric mirrors on the field of view. Thus, the UGA‑42 Geo is the perfect system for applications where simultaneous illumination of an entire area is crucial, e.g. in optogenetics where the time needed to scan a region of interest (ROI) might take too long to open a certain number of channels. The optical module is coupled into the backport to the microscope without interfering with most other existing devices (e.g. spinning disk, LSM, etc.).
Shape Illumination/ Simultaneous Illumination of Large Areas
The UGA‑42 Geo comes with preset hardware-defined geometries like circles, squares, rectangles and donuts of different size. By reshaping the laser spot, simultaneous illumination of a selected geometry is enabled. It replaces the necessity to scan larger ROIs such as entire cells, and avoids a temporal delay during the illumination.
Modularity and Flexibility
The UGA‑42 Geo includes the UGA-42 Firefly which allows free positioning of the chosen shape within the field of view. This increases the flexibility for your application and system. In addition, the UGA‑42 Geo can be combined with the UGA‑42 Caliburn ablation system. Furthermore, in addition to a single line laser light source, a laser combiner like the LDI laser diode illuminator can be coupled to the UGA‑42 Geo module to provide even more flexibility for your present and future experimental needs.
