Product Description

Meiji Techno offers the MT6800 Series Combo PLM – PCM (Polarized Light and Phase Contrast) Microscopes for Asbestos fiber identification applications. Meiji Techno manufactures these microscopes pursuant to NIOSH 9002 Reference methods and NIOSH 7400 and OSHA ID 160 Reference methods. These models use the phase contrast method for dispersion staining. Each model comes with Strain free Plan DIN brightfield POL objectives, rotatable stage with 360 degree graduations, POL/PHASE/Dispersion Staining Abbe condenser and built-in Koehler illuminator as standard equipment. The table below shows the features of each model.

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, quadruple 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.

Accessories

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 like the CC21000 1.4MP CCD camera, which offers a cost-effective, versatile solution for asbestos analysis professionals. With the included software, one can preview and capture still shots and video to a PC or Mac with USB port.
