A6 Stereo Microscope Coarse&Fine Mount

The A6 Coarse & Fine Focusing Mount is a precision mechanical stage designed for stereo microscopes with a pole diameter of 76mm.

Product Overview

The A6 Coarse & Fine Focusing Mount is a precision mechanical stage designed for stereo microscopes with a pole diameter of 76mm. It provides 0.002mm focusing precision and a 45mm vertical working distance, enabling fine adjustments during inspection tasks where depth control and repeatability are required. The mount fits directly onto a microscope body with a 32mm ID pole and maintains a centre-to-centre distance of 100mm between the pole and the focus mechanism.

Key Benefits

  • 0.002mm focusing precision allows for consistent, repeatable adjustments during detailed inspection
  • 45mm vertical working distance provides clearance for tools, samples or fixtures under the microscope head
  • Coarse and fine focus controls separate large movements from fine tuning, improving control at high magnification
  • 32mm ID pole fits standard 76mm diameter microscope bodies, ensuring compatibility with existing setups
  • Centre-to-centre distance of 100mm maintains alignment with the microscope body's optical axis

Application Scenarios

  • Precision alignment of micro-components during SMD rework or assembly under a stereo microscope
  • Consistent focus across multiple samples in a quality inspection line where repeatability is critical
  • Adjusting focus on delicate samples such as thin films, wires or micro-etched surfaces
  • Use in a teaching lab where students need to make small, controlled focus changes without overshooting
  • Integration into a custom microscope stand for a production line inspection station

Who It Is For

  • Electronics rework and assembly benches requiring fine focus control
  • Quality control labs performing repeatable microscopic inspections
  • Teaching and training labs where students need to learn focus techniques
  • Research labs working with thin or fragile samples requiring minimal movement
  • Manufacturers integrating microscope stages into custom inspection setups

Problems It Solves

  • A fixed focus mount forces the operator to reposition the sample or adjust the entire stand to change focus
  • Lack of fine focus control leads to overshooting or inconsistent focus between samples
  • Incompatible pole sizes prevent mounting a precision stage on existing microscope bodies
  • Insufficient vertical working distance limits the use of tools or fixtures under the optics
  • No centre-to-centre alignment data makes it hard to integrate the mount into a larger system

Technical Features

  • Coarse and fine focusing mechanism with separate controls for large and small adjustments
  • 32mm internal diameter pole fits a 76mm diameter microscope body pole
  • Centre-to-centre distance between pole and focus mechanism is 100mm
  • Vertical working distance of 45mm allows clearance for tools and sample holders
  • Focusing precision of 0.002mm ensures consistent depth control across multiple inspections
  • Mechanical design supports stable, vibration-free operation during fine focus adjustments

Customization Options

  • Available in standard configuration for 76mm pole bodies with 32mm ID mount
  • Can be adapted for other pole sizes upon request, subject to mechanical fit and alignment
  • Mount can be supplied with or without additional mounting hardware depending on the application

Comparison With Other Options

Standard fixed focus mountThe A6 mount adds fine focus control and 0.002mm precision, allowing repeatable adjustments without moving the sample or stand
Single coarse focus stageThe A6 includes both coarse and fine focus, reducing the risk of overshoot and enabling precise depth control at high magnification
Mount with 30mm vertical working distanceThe 45mm vertical working distance on the A6 allows more space for tools, fixtures or sample holders under the optics

Use Guide

  • Ensure the microscope body has a 76mm pole before mounting the A6 unit
  • Align the 32mm ID pole of the A6 with the 76mm body pole to maintain the 100mm centre-to-centre distance
  • Use the coarse focus to move the stage toward the sample, then switch to fine focus for final adjustment
  • Avoid applying excessive force on the fine focus knob to prevent wear or misalignment
  • Check alignment after installation to ensure the focus mechanism moves smoothly and the optical axis remains stable
Answers

Frequently Asked Questions

What is the pole diameter of the A6 mount?

The A6 mount has a 32mm internal diameter (ID) to fit a 76mm outer diameter (OD) microscope body pole.

What is the vertical working distance?

The vertical working distance is 45mm, measured from the top of the mount to the lowest point of the focus travel.

What is the focusing precision?

The focusing precision is 0.002mm, allowing for fine adjustments during detailed inspection tasks.

Can this mount be used on a microscope with a different pole size?

It is designed for 76mm pole bodies. Other pole sizes may require custom adaptation.

Is the centre-to-centre distance adjustable?

No. The centre-to-centre distance is fixed at 100mm to maintain alignment with the microscope body.

Does the mount include both coarse and fine focus controls?

Yes. The A6 mount features separate coarse and fine focus mechanisms for precise control.
