Transmitted + incident LED

Köhler illumination in the base and the included vertical illuminator: choose the optical path to suit transparent or opaque prepared specimens.

40× / 100× / 400× supplied

The 10× eyepieces pair with 4×, 10× and 40× strain-free Plan objectives. These are discrete visual settings—not a zoom.

Polarization, ready to explore

Rotating stage, polarizer, analyzer, Bertrand lens and MA988 red/quarter-wave/clear slider are included. A camera and matched adapter are not included.

What comes with the MT9930L?

Supplied optical system

MA953 trinocular head; one MA407CP 10× focusing crossline eyepiece and one MA407 10× eyepiece, both FN20; MA935 4×, MA936 10× and MA938 40× strain-free Plan objectives; centerable four-position nosepiece.

Supplied polarization tools

360° rotating ceramic-coated stage with two clips; swing-out Abbe condenser; rotating transmitted polarizer; MA956/05 graduated analyzer; focusable, centerable Bertrand lens; MA988 first-order red, quarter-wave and clear slider.

Supplied illumination

Transmitted LED and MA955LED vertical/incident LED Köhler illumination, with an incident polarizer. Dust cover and centering tools are supplied. A region-appropriate cord is supplied; confirm destination requirements.

The supplied stage rotates; the MA299 X–Y attachment and MA945 point-counting attachment are separate choices. The trinocular head is camera-ready, not a camera package.

Three specimens. Two illumination paths.

Choose the optical path by the specimen on your bench.

Application illustration: Rock thin sections. Not a microscope image.

APPLICATION ILLUSTRATION · NOT A MICROGRAPH

Rock thin sections

Trace the fabric of a rock. Compare grains, boundaries and textures in a prepared thin section. Start in plane-polarized light, then cross the analyzer and rotate the stage to follow extinction, interference colors and twinning.

Transmitted work requires a thin, transparent preparation—not an intact opaque core.

Application illustration: Transparent materials. Not a microscope image.

APPLICATION ILLUSTRATION · NOT A MICROGRAPH

Transparent materials

Look for optical anisotropy. Examine suitably prepared polymer films, fibers, glass or crystalline materials for changes in optical appearance under crossed polars. Preparation can introduce strain; compare carefully and use an appropriate protocol.

Interference colors alone do not establish chemical identity or a calibrated stress measurement.

Application illustration: Opaque surfaces. Not a microscope image.

APPLICATION ILLUSTRATION · NOT A MICROGRAPH

Opaque surfaces

Bring the light to the surface. Use the included vertical LED illuminator for appropriate polished, flat opaque ore or material surfaces. Select objectives suitable for the reflected-light specimen and its cover condition.

A rough bulk sample is not a transparent thin section. Higher-power incident objectives are separate; verify their specimen-cover specifications.

Original generated still-life illustrations, not micrographs or manufacturer photographs. They do not depict results captured with the MT9930L.

PPL, XPL or conoscopic? Choose the question first

PPL · What does the grain look like?

In transmitted plane-polarized light, insert the polarizer; leave the analyzer and Bertrand lens out. Compare color, pleochroism, relief, cleavage and grain shape. Relief depends on the specimen and mounting medium.

XPL · How does it change on rotation?

Cross the polarizer and analyzer at 90° with the Bertrand lens out. Rotate the stage to examine extinction, interference colors and twinning. A dark grain is not automatically isotropic: an anisotropic grain can be at extinction.

Conoscopic · What does the interference figure show?

Use suitable transparent crystalline grains, transmitted convergent illumination, crossed polars and the supplied Bertrand lens. Center the optics, use the 40× objective and appropriate condenser aperture, then rotate the stage. A useful figure is not guaranteed for every grain or orientation; the standard objective limits the angular cone.

Conoscopic observation is not performed under vertical illumination in the shared manual. These modes support trained interpretation, not automatic mineral chemistry or a guaranteed optical-sign determination.

From preparation to interpretation

1 · Prepare the right specimen

For transmitted petrography, use a flat, mounted rock thin section, typically around 25–30 µm, with an appropriate cover glass. Prepare films, fibers or crystals appropriately for their material; avoid preparation-induced strain. Preparation tools and consumables are separate.

2 · Center and observe

Set up illumination and center the stage/objectives according to the manual. Start at low power in PPL; compare features under XPL while rotating the stage. Keep notes on grain orientation, thickness and mounting conditions.

3 · Add a plate when useful

The supplied MA988 slider offers first-order red, quarter-wave and clear positions. Addition/subtraction can help interpret optical orientation or sign of elongation. Quantitative retardation work needs the appropriate compensator, calibration and method.

Choose the stage attachment for the work

The standard rotating stage and clips are already supplied. Add one attachment when your workflow needs controlled positioning; these are alternatives, not a stack-on pair.

MA299 · scan and reposition

The attachable mechanical stage helps move slides in X–Y for routine scanning and repositioning.

MA945 · structured point counting

Choose the point-counting attachment for a modal-analysis workflow. Select plain MA945, not an attachment intended for another microscope brand. Counting intervals support a method; they do not establish accreditation.

The shared manual directs you to remove and store the supplied clips before fitting an optional stage attachment. Verify specimen and method requirements before ordering.

Choose optional optics around the specimen

The supplied 4×, 10× and 40× objectives occupy three of four positions; one additional objective normally fits without swapping.

Optional component When it helps Decision check
MA937 · 20× transmitted 200× visual with supplied eyepieces; a middle step between 100× and 400×. For transmitted specimens; not the incident-light MA947.
MA939 · 60× transmitted 600× visual with supplied eyepieces for finer-detail work. Short working distance demands careful clearance and focusing; not an oil objective.
MA151/35/20 · 0.7× C-mount adapter A possible documentation path for a compatible camera. Confirm camera model, C/CS mount, sensor size and desired field. Manufacturer documents it with the exact MT9930L + HD2500T 2/3-inch C-mount configuration; it is not universal.

For opaque surfaces, a separately selected incident-light objective may be appropriate. MA947 is a 20× incident option, but manufacturer sources differ on its specimen-cover specification; confirm before ordering. The camera, adapter and software are separate from the bare microscope.

Three practical buying paths

1 · Petrography at the eyepieces

Choose the standard instrument for prepared thin sections and PPL/XPL viewing. The Bertrand lens and MA988 plates are already supplied.

2 · Repeatable positioning

Add MA299 for slide handling or MA945 for a point-counting workflow. Select the attachment for the job rather than both by default.

3 · Detail or documentation

Consider MA937 or MA939 for a transmitted-light magnification step. For imaging, choose a compatible camera and adapter only after checking the sensor, mount and field of view.

These are component selection paths, not bundled SKUs. Confirm the actual configuration, availability and any application-specific requirements with your order.

MT9930L buying questions

Is MT9930L transmitted-only?

No. It includes transmitted and vertical incident LED Köhler illumination. Use transmitted light with suitable transparent preparations and incident light with appropriately prepared opaque surfaces and compatible objectives.

Which magnifications are supplied?

The supplied 4×, 10× and 40× objectives paired with 10× eyepieces give 40×, 100× and 400× visual magnification. Optional MA937 adds 200×; optional MA939 gives 600×. These are separate objective settings.

Are compensating plates included?

Yes. The MA988 slider includes first-order red and quarter-wave plates and a clear position. The separately named MA904/10 Sénarmont assembly has conflicting manufacturer inclusion information; confirm the current packing list rather than assuming it is included or excluded.

What can the Bertrand lens do?

It supports transmitted conoscopic observation of interference figures from suitable transparent crystalline grains. Proper centering, convergent illumination, suitable grain orientation and operator interpretation matter; a complete figure is not guaranteed.

Is a camera included?

No. The trinocular head has a camera path, but the bare microscope is not a camera bundle. Confirm camera model, sensor, mount and field of view before selecting an adapter. The documented MA151/35/20 configuration is not a universal fit.

Will the standard microscope support point counting?

The standard stage rotates and includes clips. Structured point counting may use the separately selected MA945 attachment and an appropriate analytical protocol. The attachment does not itself certify a method.

Can it inspect opaque ore or metal?

The included incident LED illuminator supports reflected-light work on suitable polished, flat opaque surfaces. Confirm the objective and specimen-cover requirements for the specimen; do not assume the standard transmitted 40× is a dedicated polished-surface objective.

Is this a certified asbestos or clinical diagnostic system?

No such certification or clinical clearance has been established here. Method-specific work may require additional optics, sample preparation, calibration, trained personnel and applicable laboratory authorization.

Does the shared manual cover LED service?

The MT9000 series manual supports optical and mechanical operating guidance but includes legacy halogen instructions. Do not apply its halogen relamping or electrical specifications to this LED model without current manufacturer guidance.
