Condition: Used

Tested and confirmed in working condition. The unit operates at 785 nm and was manufactured in 2007 (MFD 2007). Please note the power meter shown in product images is not included — it was used solely to demonstrate laser output power during testing.

What is included:
• BRM-785-0.5-100-0.22-OC 785 nm laser module

The BRM-785-0.5-100-0.22-OC is a 785 nm fiber-coupled Raman excitation laser from B&W Tek (supplied through Ocean Optics), part of the BRM series of compact, wavelength-stabilised laser modules designed specifically for Raman spectroscopy applications. The BRM series employs narrow linewidth laser cavity technology to produce spectrally stable output suitable for demanding analytical and laboratory environments.

785 nm is the most widely used excitation wavelength for dispersive Raman spectroscopy, offering an excellent balance between Raman signal strength, reduced fluorescence from organic samples, and detector sensitivity. The fiber-coupled output with a 0.22 NA, 100 µm core fiber allows direct interfacing with standard Raman probes and spectrometer systems.

Key Features:
• Narrow spectral linewidth of 0.5 nm for high-quality Raman spectra
• 100 µm core multimode fiber output with 0.22 NA
• OC (optical connector) terminated output for easy system integration
• Compact module format suitable for OEM integration and laboratory benchtop use
• Wavelength-stabilised design for consistent, repeatable measurements
• Designed for continuous wave (CW) operation

Typical Applications:
• Raman spectroscopy (pharmaceutical, chemical, materials science)
• Hazardous materials identification
• Surface-enhanced Raman spectroscopy (SERS)
• Biomedical and life science research
• Process analytical technology (PAT)
• Academic and industrial research laboratories
