Nikon Objective Marker Red 1.8 mm for Microscope

Nikon MBW10000 Objective-Mounted Ring Marker, Red (1.8 mm) – Single Unit

The Nikon MBW10000 Objective Marker is a precision optical accessory designed to streamline sample targeting, cell localization, and region-of-interest (ROI) identification during microscopy workflows. Mounted directly into an available position on a standard microscope revolving nosepiece, this mechanical marker allows researchers to instantly imprint a highly accurate, 1.8 mm circular ink ring onto the top surface of a coverglass or microscope slide. By marking the precise optical field of view under high magnification, the MBW10000 eliminates the guesswork of relocating microscopic structures during follow-up imaging, histology cuts, microdissection, or cross-platform analysis. Factory-filled with red specialized ink, this objective marker is an essential tool for pathology, developmental biology, and material quality inspection setup.

Technical Performance & Precision Engineering

• Spring-Loaded Contact Mechanism: Features a smooth, spring-actuated barrel assembly that applies gentle, consistent downward pressure when engaged with a slide. This prevents coverglass cracking or sample displacement while ensuring a full 360-degree ink transfer.
• High-Precision Center Target Alignment: Factory-calibrated to match standard microscope parfocal distances. Rotating the marker into the active light path allows users to mark the exact center of the field of view previously observed under a high-magnification objective.
• 1.8 mm Diameter Reference Ring: Imprints a fine-line red circle with an inner ring diameter of 1.8 mm. This precise size provides a clear visual border around the target area without obscuring the core features of interest inside the circle.
• Microscopy-Grade Solvent Ink: Loaded with specialized red ink formulated to adhere cleanly to glass without beading up, smudging, or flaking off during handling or room-temperature storage.

Key Benefits & Applications

• Histopathology and Diagnostic Review: Allows pathologists to permanently mark suspicious tissue regions, cell clusters, or biopsy anomalies for secondary opinion review or slide scanning indexing.
• Laser Microdissection and Cytogenetics: Ideal for marking target cells or chromosomes under brightfield or phase contrast before transferring slides to microdissection systems or secondary preparation stations.
• Cross-Platform Microscopy Transfers: Enables easy relocation of microscopic features when transferring a slide from a light microscope to an electron microscope, fluorescence system, or profilometer.
• Non-Destructive Target Identification: Provides a clean, non-permanent reference mark on the coverglass surface that can be removed with standard isopropyl alcohol if needed.
