A4 Stereo Microscope Focusing Mount
The A4 Focusing Mount is a component-level accessory designed for stereo microscopes, with a 76mm body diameter and a 45mm vertical working distance.

Product Overview
The A4 Focusing Mount is a component-level accessory designed for stereo microscopes, with a 76mm body diameter and a 45mm vertical working distance. It provides a stable, adjustable focus mechanism for microscope heads, enabling precise height control during inspection tasks. The mount fits standard microscope bodies with a 76mm ID and supports both binocular and trinocular heads.

- Mount typeFocusing mount
- CompatibilityMicroscope bodies with 76mm ID
- Head typeBinocular / Trinocular
- AdjustmentVertical focus adjustment
Key Benefits
- 76mm body diameter matches standard stereo microscope bodies for direct fit
- 45mm vertical working distance allows clearance for tools and components under the head
- Adjustable focus mechanism enables fine control during inspection and assembly
- Durable construction supports repeated use in bench-level inspection environments
- Component-level design allows integration into custom microscope configurations
Application Scenarios
- Mounting a stereo head on a custom stand for electronics rework with consistent focus
- Replacing a worn focusing mechanism on a microscope body without replacing the entire stand
- Integrating into a configuration-to-order assembly where the focus mechanism is selected separately
- Using in a teaching lab where multiple students need consistent focus settings across instruments
- Supporting a trinocular head in a quality inspection station requiring stable focus over long sessions
Who It Is For
- Electronics manufacturers doing SMD and BGA rework and inspection
- Universities and schools running practical microscopy labs
- Quality departments requiring repeatable focus settings for inspection records
- Workshops in jewellery, watchmaking and precision assembly
- OEMs building custom microscope systems from component-level parts
Problems It Solves
- A fixed or loose focusing mechanism makes it difficult to maintain consistent focus across inspections
- Mismatched body diameter prevents direct mounting of a head onto a stand or custom frame
- Lack of a dedicated focusing mount forces the use of unstable or improvised supports
- No interchangeable focus components means the entire stand must be replaced when a mechanism fails
- Inconsistent focus height across multiple instruments leads to variability in inspection results
Technical Features
- 76mm body diameter for compatibility with standard microscope bodies
- 45mm vertical working distance for tool clearance under the optics
- Adjustable focus mechanism for precise height control
- Designed for use with binocular or trinocular stereo microscope heads
- Component-level construction allows integration into custom or OEM assemblies

Customization Options
- Available in standard configuration for 76mm ID bodies
- Can be integrated into OEM or configuration-to-order builds with specified focus travel or mounting features
- Supports use with binocular or trinocular heads depending on head selection
Comparison With Other Options
| Standard fixed-height mount | The A4 focusing mount allows vertical adjustment, so focus can be set precisely for different tasks or operators, unlike fixed mounts that require physical repositioning of the entire head. |
|---|---|
| Non-standard diameter focusing mounts | The 76mm diameter ensures compatibility with a wide range of standard stereo microscope bodies, avoiding custom adapters or modifications. |
Use Guide
- Verify the microscope body has a 76mm internal diameter before mounting
- Adjust the focus mechanism to the desired height before securing the head
- Use the vertical adjustment to maintain consistent focus across multiple inspection sessions
- Ensure the head is securely fastened to the mount to prevent movement during use
- Inspect the focus mechanism regularly for wear, especially in high-use environments
