5mm-30mm M26x0.706 Extender Ring Suitable for Mitutoyo Microscope

Key Benefits

• Extends working distance by 5mm to 30mm without changing objectives
• Secure M26x0.706 thread connection ensures alignment and stability
• Lightweight aluminum alloy construction resists deformation under repeated use
• Screw-on design allows quick installation and removal during setup
• Available in 16 standard lengths to match specific inspection or assembly needs

Application Scenarios

• Adjusting working distance for deep soldering or rework on PCBs with tight clearance
• Enabling access to deep cavities in electronic components or mechanical parts
• Extending focus reach during inspection of large or thick samples in metallurgy
• Supporting precise alignment in optical or semiconductor component assembly
• Facilitating inspection of internal features in molds, castings or tooling

Who It Is For

• Electronics manufacturers performing SMD and BGA rework with limited clearance
• Metallurgy and quality control labs inspecting thick or deep-sectioned samples
• Precision assembly workshops requiring extended focus for micro-mechanical parts
• Research labs using Mitutoyo microscopes for detailed component analysis
• Maintenance teams inspecting internal features of molds, dies or tooling

Problems It Solves

• A fixed working distance limits access to deep or recessed features on a sample
• Replacing objectives to adjust focus length causes alignment loss and delays
• Lack of extenders forces users to use longer objectives or external adapters
• Incompatible or loose adapters lead to misalignment and image shift
• No standard extension options make custom setups time-consuming and inconsistent

Technical Features

• M26x0.706 male and female threads with 4mm male thread length for secure fit
• Screw-on connection with no need for additional fasteners or tools
• Designed for use with Mitutoyo microscopes requiring M26x0.706 objective extensions
• Thread pitch matches standard M26x0.706 specification for compatibility
• Extender ring body provides stable mechanical support during focus adjustment

Comparison With Other Options

Use Guide

• Verify that your microscope objective uses M26x0.706 threads before installation
• Screw the extender ring onto the objective first, then attach to the microscope body
• Do not over-tighten; hand-tighten until secure to avoid thread damage
• Check alignment and focus after installation to confirm no image shift
• Use the shortest extender needed to achieve required working distance
