AWSO-B Series Multi-Wavelength Multi-Channel Diode Laser Module

RealLight AWSO-B Series Multi-Wavelength Multi-Channel Single-Mode Diode Laser Module Introduction

1. Product Overview
The AWSO-B series is a modular multi-channel single-mode laser light source under RealStable® by RealLight. Adopting building-block stacking architecture, it integrates self-developed single-mode fiber-coupled laser units and multi-channel independent drive circuits, supporting up to 4 rows × 9 columns (36 channels) for simultaneous or time-sharing output. Five mainstream visible wavelengths (405/450/520/638/650 nm) are standard options. Each channel is equipped with an independent built-in TEC temperature controller and standard RS232 communication interface. Compact form factor and standardized interfaces enable seamless embedding into multi-channel spectrometers, flow cytometers, array bioimaging and high-throughput testing instruments. RealLight provides full customization services including optical paths, fiber cables, laser handpieces and host control programs, catering to equipment integration demands in biomedicine, spectral detection, material characterization, array illumination and miniature laser processing.

2. Core Product Advantages
2.1. Building-block design supporting up to 36 channels with flexible wavelength combination
4×9 standardized array layout allows a maximum of 36 independent laser channels integrated in one unit. Each channel can be freely configured with 405/450/520/638/650 nm wavelengths. A single module replaces dozens of separate single-channel lasers, simplifying mechanical layout and cutting power & wiring costs, ideal for high-throughput array testing equipment.

2.2. Single-mode fiber output for all channels with pure, uniform beam
Independent precision single-mode coupling per channel; optional 4/6/9 μm single-mode fiber with NA=0.14 delivers superior beam quality and even energy distribution free of stray light. Spectral linewidth FWHM <3 nm ensures high monochromaticity, eliminating baseline noise in fluorescence excitation, microscopic imaging and high-precision spectral acquisition.

2.3. Independent TEC per channel for controllable wavelength thermal drift
Each laser channel is fitted with dedicated thermoelectric cooler and real-time temperature monitoring. Wavelength thermal drift is limited to only 0.3 nm/℃, with overall wavelength tolerance ±10 nm across 405–650 nm. Minimal wavelength and power fluctuation during long runs guarantees repeatable results for high-volume batch testing.

2.4. Independent channel control, synchronous & time-sharing triggering supported
Separate regulation for power and timing on every channel. RS232 DB9 communication allows unified command delivery from upper computers, supporting full-channel simultaneous emission or group time-sharing excitation. Adjustable pulse parameters (0~2 kHz frequency, pulse width <40 ms) fit automated high-throughput production lines.

2.5. Standardized plug-and-play module with comprehensive customization
Equipped with standard SMA905 long metal fiber pigtail (50 mm length, 3.17 mm outer diameter) and 200 cm standard fiber. Customization is available for single-channel power, fiber specifications, anti-reflection coating, multi-mode version, control software, optical lenses and therapeutic handpieces to build exclusive multi-channel light sources for OEMs.

2.6. Stable performance under wide temperature range for labs & industrial equipment
Operating temperature 10~35 ℃; storage temperature 0~60 ℃, RH 0~80%. Reliable continuous operation up to 45 minutes fits long-duration batch scanning in constant-temperature labs and regular industrial inspection machines.

3. Main Application Fields
3.1. High-Throughput Bio-Spectroscopy & Flow Detection
Multi-channel fluorescence excitation arrays for multi-lane flow cytometers, microplate fluorescence detectors and confocal array imaging. One 36-channel unit simultaneously excites multiple samples to drastically boost lab testing throughput.

3.2. Array-Based Material Analysis Equipment
Multi-wavelength synchronous irradiation arrays for high-throughput photoluminescence testing, photocatalysis reaction and thin-film optical characterization, enabling rapid performance screening of multiple material samples.

3.3. Multi-Channel Biomedical Therapeutic Devices
Array phototherapy and skin scanning light sources, matched with supporting fiber handpieces to realize large-area simultaneous photobiomodulation and non-invasive multi-target detection.

3.4. Machine Vision Array Illumination
Multi-wavelength array supplementary lighting for industrial array inspection and microscopic imaging. A single module integrates multi-color synchronous illumination to simplify optical layout of vision systems.

3.5. Miniature Precision Laser Manufacturing
Multi-channel excitation light sources for array resin curing, micro-etching and PCB micro-fabrication. Independent timing control per channel adapts to automated micro-processing production lines.

4. Product Summary
The AWSO-B series is RealLight’s flagship building-block single-mode multi-wavelength laser module supporting up to 36 independent channels. Key strengths include 36-channel single-mode output, dedicated TEC cooling per channel, RS232 multi-channel programmable control, full visible wavelength coverage (405–650 nm) and end-to-end customization capability. Narrow-linewidth single-mode beams satisfy high-precision fluorescence, microscopy and high-throughput analytical instruments. Modular architecture allows flexible channel quantity selection for OEM integrators, while standard fiber and communication interfaces lower integration barriers. Customizable optical paths, software and multi-mode variants make it the preferred domestic multi-channel laser light source for high-throughput array spectroscopy and bioimaging equipment.
