Abstract
The invention relates to a continuous spectrum light source comprising a stabilized voltage power supply, a light source, an optical fiber light source set, an optical fiber coupling lens set, and an output optical fiber. The optical fiber light source set is composed of N light spectrum channels with different wavelength coverage. Each light spectrum channel comprises orderly arranged component of a collimating lens, a band pass filter, a coupling lens, and an optical fiber. Light energies from the light source pass the collimating lens, such that parallel lights are formed; when the parallel lights pass the band pass filter, light energies with wavelengths within a range of (lambda1<(j)>, lambda2<(j)>) enter the optical fiber through the coupling lens. Optical fibers of the N light spectrum channels form an optical fiber bundle. The light energies are coupled into the output optical fiber through the optical fiber coupling lens set. Through the adjustment of light energy distribution in each light spectrum channel of the optical fiber light source set, the balance of the light energies output by the output optical fiber within an entire spectral range can be realized, such that a continuous spectrum light source is composed. Or, according to a spectrum energy distribution requirement, optical coupling efficiency of each spectrum channel of the optical fiber light source set can be adjusted, such that light energies can be arbitrarily distributed according to wavelengths.
