Multi-Wavelength Combiners

What is a Multi-Wavelength Combiner?

Multi-Wavelength Combiners or laser beam combiners allow you easily and efficiently combine multiple wavelength laser beams into one (or more) convenient outputs. The technique, called spectral beam combining (wavelength beam combining, incoherent beam combining), takes multiple different wavelength laser sources and utilizes a wavelength-sensitive beam combining optic, like a prism, diffraction grating, or dichroic mirror, to combine the beam paths and direct them to a common output.

CW 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.

Our Multi-Wavelength Combiner Products

L6Cc & L4Cc

The L6Cc and L4Cc laser beam combiners are the most compact and flexible all-in-one multi-color laser sources. Available with up to 7 laser lines input and delivery up to 4 optical fiber outputs. The modular design allows for a large choice of lasers from 375 nm up to 1064 nm and with output power up to 500 mW. The laser sources are Oxxius LaserBoxx platform. The extension modules provide the ultimate level of flexibility by integrating fast switching output ports for FRAP, adjustable split power for light sheet microscopy among other advanced functionalities.

The L6Cc and L4Cc are field upgradeable. Therefore, you can easily evolve as your needs change to preserve your investment. Furthermore, they are microprocessor controlled to provide unique features for demanding applications. The L6Cc and L4Cc are available in turnkey or OEM versions. The L6Cc is also available in high power version, integrating LBX-HPE sources with up to 1.2 W output power per line. Finally, it is coupled into a speckle-free multimode fiber.
