Melles Griot Multi-Band Dichroic Optical Beam Splitter Assembly
Part Number: 058290
Customer #: 15050495
Serial: 2014 04433
Made in USA — Melles Griot Rochester

This is a high-performance, multi-wavelength optical splitting module designed for 532 nm, 660 nm, and 785 nm laser or emission paths. The internal wavelength label “532 / 660 / 785” identifies the supported channels and confirms its intended use in advanced fluorescence or Raman-capable instruments.

These wavelength combinations are commonly used in:

• High-end flow cytometers

• NIR fluorescence detection platforms

• Raman spectroscopy systems

• Multi-laser biomedical research instruments

• Industrial or scientific optical benches

Integrated Optics Include:

• 532 nm dichroic separator (green laser channel)

• 660 nm dichroic separator (deep-red fluorescence or scatter channel)

• 785 nm NIR dichroic separator (NIR fluorescence or Raman band)

• Precision dielectric steering mirrors

• NIR-friendly prisms and optical blocks

• Factory-aligned optical housing with machined tolerances

These assemblies are extremely difficult to source except through OEM service channels for high-value research instruments. Ideal for rebuilding, servicing, or prototyping multi-band optical systems.

Condition

• Optics are bright, clear, and free of major defects

• Alignment hardware intact

• Removed from a working research instrument

• No lasers or electronics included

• Sold as-is for laboratory or research use

These multi-band dichroic assemblies are sought after by optical engineers, cytometer repair specialists, and Raman/NIR researchers due to their precision coatings and wavelength specificity.
