A5 Stereo Microscope Focusing Mount

The A5 Focusing Mount is a component-level accessory designed for stereo microscopes with a 76mm body diameter.

Product Overview

The A5 Focusing Mount is a component-level accessory designed for stereo microscopes with a 76mm body diameter. It provides vertical focusing with a 47mm working distance, allowing precise control of the objective height during inspection tasks. The mount fits directly onto a microscope body and supports standard stereo microscope heads and illumination systems.

  • Body diameter76mm
  • Working distance47mm
  • Focusing typeVertical
  • Mount typeComponent-level
  • CompatibilityStandard stereo microscope bodies (76mm diameter)

Key Benefits

  • 76mm body diameter matches standard stereo microscope bodies for direct fit
  • 47mm working distance allows clearance for tools, samples and lighting under the head
  • Vertical focusing mechanism enables smooth, repeatable height adjustment
  • Component-level design allows integration into custom microscope configurations
  • Supports interchangeable heads and illumination sources without reassembly

Application Scenarios

  • Mounting a stereo microscope head on a custom stand for a bench inspection station
  • Replacing a worn focusing mechanism on a legacy stereo microscope body
  • Building a configuration-to-order microscope with a specific working distance
  • Integrating a cold light source or ring light under the head with a stable mount
  • Using the mount in a teaching lab where multiple students need consistent focus settings

Who It Is For

  • Electronics manufacturers doing PCB and SMD inspection with custom microscope setups
  • Universities and schools building or repairing stereo microscope systems
  • Laboratories requiring a modular approach to microscope configuration
  • Workshops doing precision assembly where tool clearance under the optics is critical
  • OEMs assembling microscope systems for resale or integration into larger inspection lines

Problems It Solves

  • A fixed or unstable focusing mechanism makes it difficult to maintain consistent working distance across inspections
  • Mismatched body diameter prevents direct mounting of a new focusing mount on an existing microscope body
  • Lack of vertical adjustment forces the operator to manually move the sample or head, reducing repeatability
  • No component-level mount available for legacy or non-standard microscope bodies
  • Inconsistent focus height between instruments leads to variability in inspection results

Technical Features

  • Designed for microscope bodies with a 76mm diameter
  • Vertical focusing mechanism with 47mm working distance
  • Mechanical focus control for smooth, precise height adjustment
  • Compatible with standard stereo microscope heads and illumination systems
  • Component-level accessory for integration into custom or OEM configurations

Comparison With Other Options

Standard focusing mount with 35mm working distanceThe A5 mount provides a 47mm working distance, giving more clearance for tools and lighting under the optics.
Horizontal focusing mountThe vertical design of the A5 mount allows for more stable and repeatable focus adjustment during inspection tasks.
Integrated focusing system on a complete microscopeThe A5 mount is a component-level solution, allowing users to build or repair a microscope without replacing the entire instrument.

Use Guide

  • Ensure the microscope body has a 76mm diameter before mounting the A5 unit
  • Align the mount with the body's mounting flange and secure with the provided fasteners
  • Adjust the vertical focus knob to set the working distance to 47mm before use
  • Check that the head or illumination source is properly secured after mounting
  • Use the mount in conjunction with compatible heads and objectives to maintain optical alignment
Answers

Frequently Asked Questions

What is the body diameter required for this focusing mount?

The A5 Focusing Mount is designed for microscope bodies with a 76mm diameter.

What is the working distance of this mount?

The working distance is 47mm, measured from the top of the objective to the sample surface.

Can I use this mount with a trinocular head?

Yes. The A5 mount is compatible with standard stereo microscope heads, including trinocular configurations.

Is this mount sold as a standalone component?

Yes. The A5 Focusing Mount is a component-level accessory, sold separately for integration into custom or OEM microscope systems.

Can I adjust the working distance beyond 47mm?

The standard working distance is fixed at 47mm. To change it, use auxiliary objectives or adjust the sample height, but the mount itself does not offer variable working distance.
