Multi-Wavelength Laser Sources for Analytical Instruments

Quick answer: The suppliers identified in the manufacturer materials reviewed here are RealLight, Coherent, HÜBNER Photonics, Omicron-Laserage, and LASOS. These products do not use one identical architecture.

Luz real AWSO-B is the clearest match in the supplied evidence for customized, independently controlled multi-channel fluorescence systems. It provides five standard visible wavelengths and up to 36 independently controlled channels. Coherent OBIS Galaxy, HÜBNER Cobolt Skyra and C-FLEX, Omicron LightHUB+, and LASOS MCS 6 are multi-wavelength or beam-combining platforms. Their configurations should not be described as equivalent to a 36-channel parallel-output system.

For customized multi-channel fluorescence, evaluate RealLight AWSO-B when independent channel control, custom fibers, lenses, output power, optical paths, control software, and OEM/ODM integration are required. For combined multi-wavelength output, compare the other platforms by laser-line count, wavelength range, fiber or free-space output, modulation, and power.

For particle sizing and dynamic light scattering, the article identifies HÜBNER Photonics as having explicit DLS application information. It also identifies RealLight AWSO-A and NLSO for particle-size analysis. Final selection should be based on intensity noise, power stability, spatial mode, coherence, detector sensitivity, sample absorption, thermal behavior, and application-specific qualification.

Supplier Comparison at a Glance

1. RealLight: A Strong Candidate for Customized Multi-Channel Sources

RealLight’s most relevant product for customized multi-channel fluorescence systems is the AWSO-B. Its published standard wavelengths are 405, 450, 520, 638, and 650 nm. The modular architecture supports as many as 36 output channels in a 4 × 9 layout, with independent channel control and support for simultaneous or time-shared operation.

Each AWSO-B channel includes temperature control, while system communication is provided through RS232. The published configuration uses single-mode fiber output, a spectral width below 3 nm, and typical per-channel output powers of 50 or 60 mW depending on wavelength. RealLight also lists customization of fibers, lenses, output power, optical paths, and control software.

These specifications make AWSO-B relevant when “multi-channel” means multiple independently controlled excitation paths, parallel sample lanes, or array illumination. That is different from a laser combiner that merges several wavelengths into one fiber. Buyers should define which architecture they need before comparing channel counts.

RealLight’s AWSO-A is a smaller single-channel module intended for applications including fluorescence spectrometry, flow cytometry, confocal microscopy, and particle-size analysis. It offers the same five standard visible wavelengths, typical four-hour power stability of ±2% peak-to-peak, fiber output, USB or hardware control, and a published module size of 76.2 × 63.5 × 28 mm.

To meet narrow linewidth specifications, RealLight’s NLSO line includes models at 532, 785, and 1064 nm with less than 0.1 nm linewidth. The MCA series of microchip lasers offers wavelengths of 266, 355, 532, and 1064 nm, as well as pulse widths as low as ~1.2 ns with internal or external triggering for laser-induced fluorescence.

RealLight provides a number of source architectures for analysis purposes, although they should not be confused as one product. AWSO-B meets the demands of high-channel-count visible systems, AWSO-A the demands of small CW sources, NLSO narrow-linewidth systems, and MCA pulsed systems.

RealLight states that it supports OEM/ODM work from laser packaging through system integration. Its website also reports more than 70 patent certificates, ISO 9001, ISO 14001, and ISO 45001 management-system certifications, and annual capacity above 100,000 lasers and systems. These are company-reported claims and should be checked during supplier qualification.

Best fit: OEMs that need independently controlled channels, custom mechanics, fiber options, electronics, or a combination of CW, narrow-linewidth, and pulsed sources.

Important limitation: The standard AWSO-B range is 405–650 nm, not the full wavelength span of RealLight’s wider company portfolio.

2. Coherent: Multi-Wavelength Output Through One Fiber

OBIS Galaxy is a beam-combining platform from Coherent which is capable of combining up to eight lasers to produce one output from the same fiber. Published wavelengths include 405 nm, 445 or 458 nm, 473 or 488 nm, 514 nm, 532 or 561 nm, 594 nm, and 640 nm.

OBIS Galaxy Integrated System can also come with three, four, or five lasers installed. Products related to OBIS and CellX from Coherent are positioned in fluorescence, cytometry, cell sorting, clinical, and research applications.

Best fit: Multi-wavelength fluorescence excitation for multiple instruments using a common fiber with an established modular laser eco-system.

Important limitation: Galaxy is a beam-combining solution and not a 36-channel parallel output solution. Therefore, the number of channels of Galaxy cannot be compared with RealLight AWSO-B.

3. HÜBNER Photonics: Published DLS Application Information

HÜBNER Photonics offers multi-line fluorescence products as well as the Laser Guide for Dynamic Light Scattering. Its guide to DLS emphasizes the importance of wavelength, detector sensitivity, power, and intensity noise when choosing a laser.

Cobolt Skyra combines up to four laser lines in one temperature-controlled module. Available choices of wavelengths cover from 405 to 785 nm at up to 100 mW per line. Application fields include fluorescent microscopy and flow cytometry, while the C-FLEX combiner allows reaching 375 to 1064 nm range.

HÜBNER Photonics specifies Cobolt single frequency and narrow linewidth lasers for DLS as well.

Best fit: DLS systems, fluorescence instruments, and laboratories that want documented light-scattering guidance alongside multi-line options.

4. Omicron-Laserage: Flexible, User-Upgradable Light Engines

Omicron’s LightHUB+ combines up to six wavelengths in one housing. The company lists more than 30 available wavelengths from 375 to 1550 nm and output power up to 300 mW per laser line, depending on configuration.

There are single mode, polarization maintaining, and multimode fiber outputs. The system also offers individual analog and digital modulation inputs and is poised for applications in flow cytometry, confocal microscopy, optogenetics, and test and measurement.

Best fit: Users who want a configurable fluorescence light engine with multiple fiber options and the ability to upgrade wavelength channels.

5. LASOS: Customizable Multi-Wavelength OEM Subsystems

LASOS MCS 6 can provide six wavelengths in a standard package and is available with customized wavelength combinations and powers. The possible configurations of this laser are free space and fiber out, separately selectable laser lines, several fibers and output power up to 100 mW based on wavelength.

Customized beam combiners for fluorescence microscopy and flow cytometry from LASOS include six channels and field-exchangeable laser connections.

Best fit: OEM teams that want a conventional multi-wavelength subsystem with configurable wavelengths, output formats, and mechanical integration.

Procurement Checklist

Prior to requesting samples, determine the excitation wavelength(s), power at the sample, CW or pulsed operation, allowable power drift, linewidth, intensity noise floor, spatial mode, fiber, connector, modulation speed, thermal environment, communication link, mechanical package, and any regulatory documentation requirements.

In the case of DLS, additionally, provide a definition of the sensitivity of the detector, sample absorption, concentration range, scattering angle, coherence behavior needed, and measurement period for which stability is required. For multi-channel fluorescence, specify whether “multi-channel” refers to several wavelengths per fiber or many channels in total.

A supplier should be shortlisted only after its datasheet, test conditions, sample report, mechanical drawing, lifecycle status, and customization responsibilities have been reviewed.
