Aven Tools 26800B-703 SPZ-50 Binocular Stereo Zoom Microscope, 6.7x–50x, Double Arm Boom Stand with Table Clamp
Aven Tools 26800B-703 SPZ-50 Binocular Stereo Zoom Microscope, 6.7x–50x, Double Arm Boom Stand with Table Clamp
The Aven Tools 26800B-703 combines an SPZ-50 binocular stereo zoom microscope with a double arm boom stand, heavy-duty table clamp and integrated LED ring-light focus mount. Supplied 10x eyepieces deliver 6.7x–50x magnification, while a 108 mm working distance leaves room beneath the optics for inspection and precision assembly. Move from a broad overview to fine detail, then reposition the double-bar arm across your work area without a large stand base occupying the bench.

Choosing a Workstation Configuration
| Configuration | Selection consideration |
|---|---|
| This double arm table-clamp system | Flexible positioning across a larger work area with ring illumination and no large bench-top base. |
| Track stand with top and bottom lighting | Consider when a dedicated stand base and transmitted-light viewing are priorities. |
| Trinocular or digital imaging system | Consider when a camera connection or monitor-based viewing is required. This SKU is a binocular optical system, not the generic SPZV-50 trinocular configuration. |
Frequently Asked Questions
What magnification does the 26800B-703 provide?
The supplied 10x eyepieces provide a 6.7x–50x optical magnification range. Optional eyepieces and auxiliary lenses can change that range.
What lighting is included?
The system includes an integrated LED ring light and focus mount with 60 LEDs, variable lighting control, 5600 K white light and a power supply.
How does the stand attach to the bench?
A heavy-duty table clamp attaches to the side of the workbench. Dual locks help stabilize the mounting, while the double arm allows horizontal positioning and vertical adjustment.
How much working distance is available?
Standard working distance is 108 mm without an auxiliary lens. Optional auxiliary lenses change the working distance, as listed in the specification table.
Is this a binocular or trinocular microscope?
This SKU is the SPZ-50 binocular system. It should not be confused with Aven's SPZV-50 trinocular model or a camera-and-monitor configuration.
Can the eyepieces be adjusted for different users?
Yes. Interpupillary distance adjusts from 52 to 75 mm, and both eyepiece tubes have diopter adjustment. The supplied eyepieces have a 17 mm high eyepoint.
Are the optional auxiliary lenses included?
The standard microscope package includes two 10x eyepieces. The 0.5x, 0.75x, 1.6x and 2x auxiliary lenses and alternative eyepieces are optional.
