PLM (Polarizing Light Microscopy):
This method is useful for the qualitative identification of asbestos and the semi-quantitative
determination of asbestos in bulk samples. This method measures the percentage of asbestos as perceived by the analyst in comparison to standard projections, photographs and experience. The quality of the results are dependant upon the skill and judgment of the operator.

PCM (Phase Contrast Microscopy):
Phase contrast microscopy is the method that is primarily used for estimating asbestos concentrations of airborne fibers. This method is quick and can be performed on-site for a rapid determination of concentrations of asbestos fibers in the air. Phase contrast microscopy does not positively differentiate between asbestos and other fibers. Positive identification of asbestos fiber must be performed using PLM (Polarized Light Microscopy) or Electron Microscopy (Method 7402).

Trinocular

VIEWING HEADS Model MA952 is the Siedentopf-type binocular head and Model MA953 is the trinocular head for camera integration. Each head has the 23.2mm eyetubes inclined at 30 degrees with the left eyetube having graduated diopter settings. The interpupillary distance is adjustable between 53mm – 75mm. An 80/20 beamsplitter for the trinocular tube can be engaged for photo work.Each head has the new integrated reticle angle compensation system. When the IP distance or number is changed, the crossline reticle remains perpendicular in the FOV.
EYEPIECES 10X Widefield High Eyepoint eyepiece F.N. 20, 10X Widefield High Eyepoint focusable eyepiece that has a 21mm crossline reticule and guide pin, and 10X Widefield High Eyepoint Compensating Focusing eyepiece, F.N. 20 with Walton & Beckett reticle are standard.
OBJECTIVE CHANGER The smooth-operating, ball bearing mounted, quintuple nosepiece provides effortless objective changes.
OBJECTIVES Meiji Techno offers an assortment of U. Planachromat Phase and S. Planachromat Polarizing Infinity Corrected objectives.
STAGE Ceramic coated 360 degree rotatable fully indexed stage with vernier and stage clips.
CONDENSER Strain free Abbe condenser, N.A. 1.25 with centerable annuli for 10X, 20X, 40X phase or 10X, 20X, 40X dispersion staining objectives in sliding mount, with iris diaphragm and dovetail mount.
ILLUMINATION Powerful 30 watt transmitted light Koehler halogen illumination provides enhanced image quality and brightness for the observation of specimens.
ACESSORIES All MT6800 Series models come with a first order red compensating plate (also called Gypsum or Sensitive Tint Plate), an analyzer in sliding mount, Bertrand lens, Blue Clear and Green Interference filters, Centering Telescope, and Stage Micrometer.
PHOTOMICROGRAPHY Meiji Techno offers a broad range of digital video cameras which offers excellent sensitivity, high resolution and a wide dynamic range for the most demanding brightfield and darkfield microscopy applications including clinical pathology and cytology, life sciences and geology. Some models has included software, that can preview and capture still shots and live videos to a PC or Mac with USB port or HDMI connectivity.
