STL9 Stereo Microscope Boom Stand
The STL9 Boom Stand is a rigid, adjustable support for stereo microscopes with a 493mm vertical post and 470mm horizontal reach.

Product Overview
The STL9 Boom Stand is a rigid, adjustable support for stereo microscopes with a 493mm vertical post and 470mm horizontal reach. It allows the microscope head to be positioned at any angle or height within a 380mm moving range, enabling observation of large or irregularly shaped objects without repositioning the workpiece. The front hand wheel controls the vertical movement with a 38mm diameter knob, and the stand features a stable base measuring 252x252x30mm.
- Vertical post height493mm
- Vertical post diameterФ38mm
- Horizontal arm length470mm
- Moving range380mm
- Front hand wheel diameterФ38mm
- Front connecting rod sizeФ32mm / Ф25mm
Key Benefits
- 380mm horizontal moving range lets the microscope head access objects beyond the base edge
- 493mm vertical post supports heads at high or low working positions
- Front hand wheel with 38mm diameter allows smooth, precise vertical adjustment
- Stable base (252x252x30mm) resists tipping during operation
- Adjustable horizontal arm (470mm length) positions the head over any part of the work area
- Supports heavy microscope heads with a 38mm diameter vertical post
- Allows continuous observation of large or complex parts without moving the workpiece
Application Scenarios
- Inspecting large PCBs or circuit boards that extend beyond a standard bench stand
- Observing irregularly shaped metal castings or machined parts on a workbench
- Positioning a microscope head over a large assembly fixture or jig
- Adjusting the head height for multiple operators with different eye levels
- Using the stand in a quality lab where the workpiece must remain fixed during inspection
Who It Is For
- Electronics manufacturers inspecting large PCBs or assemblies
- Metallurgy and foundry labs testing large castings or components
- Precision engineering workshops handling irregularly shaped parts
- Teaching labs demonstrating large-scale microstructures or mechanical assemblies
- Quality control departments requiring fixed workpiece positioning
Problems It Solves
- A fixed stand limits the microscope head to a single position, forcing the workpiece to be moved
- Small horizontal reach prevents access to parts that extend beyond the base
- Lack of vertical adjustment makes it hard to accommodate different operator heights
- Unstable base causes vibration during high-magnification inspection
- No support for heavy heads leads to sagging or misalignment over time

Customization Options
- Available in standard configuration with 38mm vertical post and 470mm arm
- Can be adapted to fit different head mounting standards upon request
- Base can be modified for non-flat or uneven work surfaces if specified
Comparison With Other Options
| STL5 Stand | The STL9 has a longer horizontal arm (470mm vs 300mm) and greater vertical reach (493mm vs 350mm), making it better for large workpieces. |
|---|---|
| Fixed Bench Stand | The STL9 allows full horizontal and vertical movement; a fixed stand requires repositioning the workpiece for each observation point. |
| Floor Stand | The STL9 is a boom stand with a smaller footprint and higher adjustability; floor stands are fixed to the floor and less flexible. |
Use Guide
- Ensure the base is placed on a flat, stable surface before mounting the microscope head
- Adjust the front hand wheel slowly to avoid sudden drops or jerks
- Check that the horizontal arm is fully extended before applying load
- Do not exceed the 380mm moving range to prevent mechanical stress
- Secure the microscope head with the mounting screw after positioning

Frequently Asked Questions
What is the maximum horizontal reach of the STL9 stand?
470mm from the vertical post to the end of the horizontal arm.
Can the STL9 stand support a heavy microscope head?
Yes. The 38mm diameter vertical post and steel construction support standard stereo microscope heads.
Is the front hand wheel easy to turn?
Yes. The 38mm diameter hand wheel provides good grip and smooth vertical adjustment.
What is the moving range of the stand?
380mm, allowing the head to move vertically across a wide range.
Can I use this stand with any stereo microscope head?
Yes, as long as the head uses a standard mounting interface compatible with a 38mm post.
