    Area of Science:

    • Biomedical Optics
    • Optical Engineering
    • Instrumentation Science

    Background:

    • Multispectral illumination is crucial for diverse biomedical applications.
    • A need exists for spectrally tunable, fiber-coupled multispectral light sources suitable for compact systems.
    • Existing solutions often lack the required flexibility or are not optimized for small footprints.

    Purpose of the Study:

    • To present an open-source guide for constructing a compact, adaptable, fiber-coupled multispectral illumination platform.
    • To characterize the performance of the developed LED-based platform.
    • To make the design accessible for broader adoption in research and development.

    Main Methods:

    • Construction of a multispectral illumination platform using five LEDs with wavelengths ranging from 455 nm to 940 nm.
    • Coupling the LED output to a multimode optical fiber.
    • Comprehensive characterization of the platform's output power, spectral performance, and stability.
    • Provision of all design blueprints, assembly instructions, parts lists, source code, and a graphical interface via a Zenodo repository.

    Main Results:

    • Successful construction of a compact and adaptable fiber-coupled multispectral illumination platform.
    • The platform features five LEDs covering a broad spectral range (455-940 nm).
    • The system is capable of delivering milliwatt-level optical output power when coupled to a multimode fiber, a novel capability for multi-LED systems.
    • Key performance metrics including output power, spectral characteristics, and operational stability were thoroughly evaluated.

    Conclusions:

    • The developed open-source platform provides a versatile and accessible multispectral illumination solution for biomedical applications.
    • This compact, fiber-coupled system addresses the scarcity of tunable light sources for small-footprint requirements.
    • The availability of comprehensive design documentation and source code facilitates replication and further innovation.
