XLB 25mm Stereo Microscope Focusing Mount
The XLB 25mm monocular focusing mount is designed for use with microscope bodies that have a 50mm pole diameter.

Product Overview
The XLB 25mm monocular focusing mount is designed for use with microscope bodies that have a 50mm pole diameter. It provides a 42mm vertical working distance and a centre-to-centre distance of 140mm between the mounting points. The mount accepts a 25mm ID optical head and is intended for integration into stereo microscope systems requiring precise vertical focusing control.

Key Benefits
- 42mm vertical working distance allows clearance for tools, probes or samples under the optical head
- Centre-to-centre distance of 140mm ensures alignment with standard stereo microscope body configurations
- 25mm ID mounting interface fits heads with a 25mm inner diameter, enabling secure attachment
- 50mm pole diameter compatibility allows direct fit to standard microscope bodies
- Monocular head design simplifies setup for single-operator inspection tasks
Application Scenarios
- Mounting a monocular head on a stereo microscope body for bench-level inspection with a fixed optical axis
- Integrating a focusing mount into a custom-built inspection station for electronics or precision assembly
- Replacing a damaged or non-standard focusing mount on a legacy stereo microscope system
- Using the mount in a teaching lab where a single operator needs consistent focus across multiple samples
- Setting up a dedicated inspection station with a fixed working distance for repetitive quality checks
Who It Is For
- Electronics manufacturers performing SMD and BGA inspection with fixed-position setups
- Teaching laboratories requiring durable, replaceable focusing mounts for student use
- Precision assembly workshops needing a stable, repeatable mounting solution
- Maintenance teams replacing worn or mismatched focusing mounts on older microscope bodies
- Lab technicians integrating components into custom inspection stations
Problems It Solves
- A non-standard or missing focusing mount prevents the use of a monocular head on a 50mm pole body
- Lack of vertical working distance forces operators to work too close to the sample, risking damage
- Mismatched ID or pole diameter between head and mount leads to instability or misalignment
- No centre-to-centre specification causes misalignment when mounting multiple components
- Inability to replace a broken mount without sourcing a full new microscope system
Technical Features
- Monocular head design with 25mm inner diameter for optical head mounting
- 50mm pole diameter for compatibility with standard microscope bodies
- Centre-to-centre distance of 140mm between mounting points
- Vertical working distance of 42mm for clearance under the optical head
- Designed for use with stereo microscope bodies requiring a focusing mount

Customization Options
- Available in monocular configuration only
- Mounts directly onto 50mm pole bodies with no additional adapters required
- Designed for use with 25mm ID optical heads; no alternative head sizes provided
Comparison With Other Options
| XLB 25mm Binocular Focusing Mount | Same 25mm ID, 50mm pole, 140mm centre-to-centre and 42mm vertical working distance; differs only in head configuration - binocular vs monocular. |
|---|---|
| XLB 30mm Focusing Mount | The 30mm ID version is not compatible with 25mm heads; this mount is for 25mm ID heads only. |
| Standard non-focusing mount | This mount includes vertical focusing capability; a non-focusing mount would require manual adjustment of the entire body or head position |
Use Guide
- Ensure the microscope body has a 50mm pole diameter before mounting
- Align the 25mm ID head with the mount before securing; verify no lateral play
- Set the vertical working distance to 42mm to maintain clearance for tools or probes
- Use the centre-to-centre distance of 140mm as a reference when aligning with other components
- Check for stability after mounting; the mount should not wobble under normal use

View DetailsFrequently Asked Questions
What is the vertical working distance of this focusing mount?
42mm. This allows clearance for tools, probes or sample holders under the optical head.
Can I use this mount with a 30mm ID head?
No. The mount is designed for 25mm ID heads only. A 30mm ID head would not fit securely.
Is this mount compatible with all stereo microscope bodies?
Only with bodies that have a 50mm pole diameter and a 140mm centre-to-centre distance between mounting points.
Does this mount include focusing adjustment?
Yes. It provides vertical focusing movement with a 42mm working distance.
Can I use a binocular head on this mount?
No. This mount is designed for monocular heads only. A binocular head would require a different mount type.
What is the centre-to-centre distance?
140mm. This ensures alignment with standard stereo microscope body configurations.
