Inclined Stereo Microscope, with Extension Pillar

Quick Answer: The Inclined Stereo Microscope, with Extension Pillar is an angled-head stereo microscope on a lengthened pillar, which lets the head be set higher above the stage. The stereo microscope with extension pillar is chosen for specimens too tall to fit under a standard stand.

What the Extension Pillar Adds

Every stereo microscope focuses at a fixed working distance below its objective. On a standard pillar, the head can only be raised so far, which caps the height of object that can be brought into focus. An extension pillar adds length to the post, so the head can be clamped higher and tall objects fit underneath: a hand specimen of rock, a fossil still in its matrix, a whole fruit or a seedling in a small pot.

The trade-off is stability. A head clamped high on a tall pillar has a longer lever arm, so the base must stand firm, and knocks travel up the pillar as vibration. For flat specimens, lower the head on the pillar rather than working at full height.

This is the inclined-head counterpart of the student stereo microscope with extension pillar. For ordinary dissection-sized specimens, the basic inclined stereo microscope is sufficient.

Applications

• Geology labs examining hand specimens, fossils and crystals in matrix
• Botany work on whole flowers still on the stem and seedlings in pots
• Checking fruit and seed surfaces for pest damage
• Inspecting assembled models or components that cannot be taken apart

Care & Handling

• Support the head of the stereo microscope with extension pillar with one hand before loosening its clamp, so it cannot slide down onto the specimen.
• Where a safety collar is fitted below the head clamp, keep it tightened in place.
• Wipe rock dust and soil off the base and pillar after use, because grit on the pillar scores it and makes the clamp grip unevenly.
• Place the microscope towards the back of the bench, where the tall pillar is less likely to be knocked.

Frequently Asked Questions

How tall a specimen will fit?

The listing does not give the pillar height. The specimen must fit between the stage and the objective with the head at its working distance, so measure your tallest object and compare it with the clearance stated on the quotation.

Does a taller pillar change magnification?

No. Magnification depends on the optics. The pillar changes only how high the head can be mounted, and therefore how tall an object can be brought into focus.

Why does the image shake?

A head mounted high on the pillar amplifies vibration from the bench. Lower the head as far as the specimen allows, use a solid bench and avoid leaning on the table while viewing.

Can I look at a potted plant without disturbing it?

Yes, if the pot fits under the raised head. Stand the pot on the base, lower the head to working distance above the leaf or flower, and light that part from the side.

What is a safety collar?

A ring clamped to the pillar just below the head bracket. If the head clamp is loosened, the head rests on the collar instead of sliding down onto the specimen.

How should rock specimens be prepared for viewing?

Brush off dust and wet the surface with a little water, which shows colour and grain boundaries more clearly. A freshly broken face shows crystals better than a weathered one.
