* For each leg The RGB1-FC combines three fiber inputs into one output beam. The combiner has FC/PC inputs for red (640 ± 5 nm), green (535 ± 5 nm), and blue (488 ± 5 nm) lasers and couples the combined output into a single mode fiber with a Ø3 mm jacket. RGB combiners are often used to illuminate multiple fluorophores in confocal microscopy (and produces images similar to those shown above), which can save space compared to using a more traditional free-space illumination method. For other connector options and wavelength combinations, please contact your local Thorlabs Technical Support team. Fiber Specifications| Fiber Type | 460HP |
