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.

Would it be possible to use a FC/APC connector to the RGB FC/PC input port? I have a laser whose fibre pigtail is APC type.

Other wavelengths would be of interest, even if the coupling was lossy. Wavelengths I work with include 473, 488, 532, 635 & 670nm - 4 of these are provided by an MCLS-1. The lower wavelengths are of the greater interest.

Response from Chris at Thorlabs: Thank you for using our web feedback. We may be able to provide an RGB combiner with a custom wavelength configuration for you. I will contact you directly to discuss this further.

Would it be possible to get this for 405, 488, and 638nm, coupling into your new S405-XP 400-680nm single mode fiber? I am interested in potentially using this module with your MCLS1 4 channel laser diode source.
