Product Description
Large High-Precision 12-Facet Polygon Mirror Scanner – Heavy-Duty Industrial Surplus
This is a professional-grade, 12-sided rotating polygon mirror designed for high-speed, high-duty-cycle laser scanning applications such as laser printing, barcode reading, and optical measurement systems. Featuring a massive, balanced steel mounting post, it was engineered for stable, high-RPM operation in demanding industrial environments.
Key Specifications:
-
Configuration: 12-sided regular polygon (dodecagon)
-
Dimensions: ~95 mm across flats, ~85 mm height, 10 mm thick (rigid substrate)
-
Facet Coating: First-surface protected silver or enhanced aluminum – >95% broadband reflectivity across visible to NIR
-
Mount: 35 mm diameter steel post with keyway and set screws for direct, balanced motor coupling
-
Balance: Professionally balanced for high-speed rotation (minimal wobble)
-
Condition: Excellent surplus – pristine mirror facets, no chips or coating damage
Why This Scanner Is Exceptional:
-
Industrial Provenance: Built for OEM laser printing/scanning engines, ensuring precision and durability far beyond hobbyist components.
-
Ready-to-Integrate Mount: The massive steel post is designed for direct mounting to a compatible motor shaft, simplifying system integration.
-
Rare Find: Large, multi-facet polygon mirrors with professional mounts are uncommon on the surplus market.
Applications:
-
Laser Scanning Systems: Core component for building custom line scanners, laser projectors, or LIDAR prototypes.
-
Vintage Equipment Restoration: Perfect for restoring classic HP, Canon, or Xerox laser printer engines or industrial scanners.
-
Optical Research & Education: For university labs teaching scanning optics, opto-mechanics, or photonics.
-
High-Speed Imaging/Inspection: Potential use in custom line-scan cameras or inspection systems.
Important Notes:
-
High-RPM Use: This mirror is balanced for high-speed operation but requires a precision motor and controller for safe and effective use.
-
Handling Care: Avoid touching the mirror facets. The coating, while protected, can be damaged by fingerprints or abrasives.
