Binocular Asbestos PCM Microscope

Meiji Techno, MT6520, Binocular Asbestos PCM Microscope, 6V 30W Halogen IlluminatorFeatures:DIN standard eyepieces HWF 10X and DIN HWF 10X-F focusing eyepieces with Walton and Beckett reticle (Type G-22 with 3:1 aspect ratio)Mechanical X-Y stage with attached finger assemblyAchromatic condenser N.A. 1.25 with iris, filter tray and 40X positive Phase annulus in sliding mountCoaxial coarse and fine focus adjustment with graduation, reading 2 microns per division with tension adjustment and safety auto focus stopBuilt-in Koehler illuminator with 6V 30W halogen lamp and variable intensity controlGIF (Green interference Filter) 546nm, 29.8 diameterCentering TelescopeStage micrometer 1mm divided into 100 units (each division= 0.01 mm)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. The MT6520 is a newly designed PCM (Phase Contrast) Compound Microscope for Asbestos fiber counting applications. Built in Koehler Transmitted illuminator with 6V 30W Halogen lamp and variable intensity control. Equipped with Phase contrast ∞ Infinity Corrected objectives, GIF filter, Walton and Beckett reticle and a centering telescope and stage micrometer.
