Claim 35:
36. An optical source module comprising: a housing defining an enclosure of free space; first, second and third superluminescent light emitting diode, SLED, sources arranged in the enclosure to emit first, second and third SLED beams having respective first, second and third wavelength ranges selected from different ones of red, green and blue visible wavelengths, the first, second and third beams propagating in the free space along first, second and third beam paths; a fourth SLED source arranged in the enclosure to emit a fourth SLED beam having a fourth wavelength range with a center wavelength at a near-infrared or infrared wavelength, the fourth beam propagating in the free space along a fourth beam path; a first beam combiner arranged in the enclosure to receive the first SLED beam and the second SLED beam, and to combine them into a combined SLED beam with a spectrum including the first and second wavelength ranges and extending in the free space along a combined beam path; a second beam combiner arranged in the enclosure to receive the combined first and second SLED beam and the third SLED beam, and to combine them to form a combined SLED beam with a spectrum including the first, second and third wavelength ranges into the combined beam path; a third beam combiner arranged in the enclosure to receive the combined first to third SLED beam and the fourth SLED beam, and to combine them to form a combined SLED beam into the combined beam path.
