3 420,00 € incl. VAT - 2 850,00 € excl. VAT
The FIGU (Fiber Injection and Guiding Unit) is mounted on the telescope focus (F/6) to inject the starlight into an optical fiber (50µm).
All about the product:
Description
The FIGU is mounted at the telescope’s focus to inject starlight into the eShel’s (or Whoppshel’s) optical fiber (50µm). A guiding camera (not included) allows you to observe the telescope field of view and locate the target star; then guide on this star. Alternatively, calibration light can be injected from the calibration module via a 200 µm optical fiber also connected to the FIGU A remote-controlled mirror allows you to switch from one source to another.
Example of guiding image field of view with the 50 µm object fiber location
