Industry Leading CW Laser Combiners: Critical for the Life Sciences

    What's so critical about laser combiners?

    Complicated Laser Alignment-1CW multi-wavelength combiners have proven to be a critical component in Life Science applications, reducing time, cost, and complexity, and fundamentally changing these applications, allowing for increased efficiency and ease of use. Given the immense degree of complexity and time involved with combining multiple laser beams into a confocal microscope, multi-wavelength combiner modules have flooded into the market in recent years. These plug-n-play style modules allow for swappable laser modules and quick and easy coupling with a confocal microscope, saving hours in precision alignment efforts. Laser combiner modules also help to avoid further compounding the complexity of the process, resulting from trying to select multiple different wavelength sources from various laser models and even from various manufacturers, likely with differing specifications. With a huge selection of wavelength combiners on the market, picking the right solution for your needs can be a difficult task.


    The L4Cc and L6Cc are flexible by design.

    L4Cc L6Cc Combiner Side-By-SideOur engineers had versatility in mind when designing the L4Cc and the L6Cc. The platform's modular design allowed for the L6Cc to be the most compact and flexible all-in-one multicolor laser source, which can be configured with up to 7 laser inputs, up to 4 optical fiber outputs, and allows you to choose any combination from a wide range of wavelengths from 375 nm up to 1064 nm, with output power up to 500mW. The L6Cc and L4Cc are available in turnkey or OEM versions and are field upgradeable to evolve with your changing needs, helping to preserve your investment. They are microprocessor controlled to provide unique features for demanding applications. The performance, versatility, and wide range of options and capabilities combine to make the LaserBoxx Combiner series a preferred solution for applications like FRAP,  confocal fluorescence microscopy, flow cytometry, and DNA sequencing. The L6Cc is also available in a high power format with the integration of the Oxxius LaserBoxx LBX-HPE modules, with up to 1.2W output power per line, and is available with a speckle-free multimode fiber output.

    Life Science Applications – Basic CW Laser Specifications:

    Most Life Science applications using CW Laser Modules involve fluorescence excitation and require a very low-noise laser with power stability and good beam quality. Except for Raman spectroscopy, many of these applications do not need a single longitudinal mode (SLM) laser. The wavelength and output power needed varies. Most are typically fiber coupled, but some require free space output.
