Phase Contrast Microscope

Advanced routine laboratory microscope for brightfield and phase contrast observations with IOS W-PLAN objectives and rackless stage. Ideal for Asbestos analysis in accordance to international rules with 12.5x eyepieces and Walton & Becket graticule to perform perfect asbestos fibers analysis at a glance. The high-efficiency X-LED3 makes it reliable for all transmitted light observations. Features: Observation mode: Brightfield, phase contrast. Head: Trinocular (fixed 50/50), 30° inclined, 360° rotating. Interpupillary distance: Adjustable between 50 and 75 mm. Dioptric adjustment: On the left eyepiece tube. Eyepieces: WF10x/22 mm, high eye-point and WF12.5x/18 mm with dioptric adjustment, one with Walton & Beckett graticule. Nosepiece: Quintuple revolving nosepiece, rotation on ball bearings. Objectives: – IOS W-PLAN 4x/0.10 – IOS W-PLAN 10x/0.25 – IOS W-PLAN PH 40x/0.65 – IOS W-PLAN 100x/1.25 (Oil) All with anti-fungus treatment. Specimen stage: Double layer rackless mechanical stage, 233×147 mm, 78×54 mm X-Y range. Focusing: Coaxial coarse (adjustable tension) and fine focusing mechanism with limit stop to prevent the contact between objective and specimen. Condenser: Abbe N.A. 1.25, with objective-coded iris diaphragm, focusable and centerable. With 40x phase contrast slider. Transmitted illumination (Full Koehler type):  X-LED³ with white 3.6 W LED (6,300K) with brightness control. Multi-plug 100-240Vac/6Vdc external power supply.   Technical Specifications: Observation Method – Transmitted Light Brightfield Yes   Phase contrast (Positive type) Yes   Darkfield As optional   Simple polarized light As optional Main Body Type Upright   Construction material Aluminum die-cast   Trasportation handle Yes Head Type Trinocular (Siedentopf)   Split ratio 50/50   Inclination 30°   360° rotating Yes   Interpupillary distance (mm) 50-75   Tube inner diameter (mm) 30 Eyepieces Field number (mm) 22   Magnification 10x   Planar type Yes   Micrometric scale As optional   Diameter of micrometer glass (mm) 26   High eyepoint (for glass wearers) Yes   Rubber cup Yes   Retractable protections Yes Nosepiece Positions Quintuple   Reversed Yes   Bi-directional Yes   Rotation on ball bearings Yes   Objective thread RMS Objectives Optical system ∞   Anti-fungus treatment Yes   Parfocal distance (mm) 45   Standard magnifications 40x-1000x   Type IOS W-PLAN   Objectives included 4x/0.10, W.D. 17.3 mm 10x/0.25, W.D. 10 mm PH 40x/0.65, W.D. 0.54 mm 100x/1.25 (Oil), W.D. 0.13 mm Stage Type Double layer   Dimensions (mm) 233×147   Moving mechanism Rackless   Moving range (mm) 78×54   Material Anti-scratch painting   Specimen holder Yes   Slide number 2   X-Y Vernier scale Yes   Vernier scale accuracy (mm) 0.1 Condenser – Multiple Position Type Abbe.
