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. This item is a passive optical assembly intended for research, educational, and industrial use only. It is not a medical device, not calibrated, and not intended for clinical or diagnostic applications. Item will ship fully insured with signature required
