Brightfield&Darkfield Biological Microscope BM400D series:Description:Composed the professional darkfield kits with the advanced biological microscope BM400, it becomes the darkfield microscope.it is easy to change bright field obervation into the darfield observation. It is a simple procedure which can be used on live transparent specimens, specimens which normally need to be stained (and therefore killed).you can use the dark field in the research of live bacterium, as well as mounted cells and tissues. It is more useful in examining external details, such as outlines, edges, grain boundaries and surface defects than internal structure.Features: 1. New machining facility and advanced alignment technology2. Complete functions and outfit of binocular microscope,trinocular head is vailable3. Comfortable operation with updated and ergonomic design4. Professional darkfield condenser, and darkfield 100x lens with cone diaphgragm.5. more useful in examining external details, such as outlines, edges, grain boundaries and surface defects6. A digital camera can be added to the trinocular head to take photos and videos Standard Specification400DB 400DTViewing HeadCompensation Binocular head inclined at30°, Interpupillary Distance 55-75mm,√ Compensation Trinocular head inclined at30°, Interpupillary Distance 55-75mm, √EyepieceWide Field EWF10X/20eyepiece√√P16X eyepieceOOWF10X eyepiece with metal pointerOOWF10X eyepiece with reticle scale 0.1mmOONosepieceBackward Quadruple Nosepiece√√Backward Quintuple NosepieceOOObjectivesAchromatic Objective 4X 10X 40X(S), 100X(S.oil)√√Achromatic objective 100X with cone diaphragm for dark field √√Plan Achromatic Objective 4X 10X 40X(S), 100X(S.oil)OOInfinite Semi-Plan Achromatic Objective 4X 10X 40X(S), 100X(S.oil)OOInfinite Plan Achromatic Objective 4X 10X 40X(S), 100X(S.oil)OOStageDouble Layers Mechanical Stage:140X140, Moving range:75X50mm√√CondenserAbbe Condenser N.A.=1.25 With Iris Diaphragm and Filters√√Dark Field Condenser N.A. 0.7-0.9 (Dry)√√Focusing SystemCoaxial Coarse&Fine Adjustment, Fine Division 0.002mm, Moving range:20mm√√CollectorHigh Brightness Collector√√Kohler Illumination with Iris DiaphragmOOIlluminationAC220V/110V, Super Light 3W LED illumination, Brightness Adjustable.√√AC220V/110V, 6V20W, Halogen Lamp, Brightness Adjustable.OOFiltersGreen and Blue Filters√√Optional AccessoriesPolarization Attachment (Analyzer and polarizer)OOSimple Phase contrast kitOOSliding Phase contrast kitOOTurret Phase contrast KitOOTemperature Controlled StageOOVideo Adapter With C mountOOEpi-fluorescent AttachmentOOHigh resolution COMS Digital Camera 1.3MP, 2.0MP, 3.0MP, 5.0MP, 9.0MP with softwareOONote:"√" Standard Specification, "O"Optional Parts Binocular Darkfield&brightfield Biological Microscope BM400D Trinocular Brightfield&darkfield Biological microscope BM400D with external digital camera
