AmScope D100A-MS Dual-View Compound Monocular Microscope - 40X-640X Magnification with Brightfield & Single-Lens Condenser | Ideal for Lab Research, Classroom Education & Home Science Experiments

The AmScope D100A-MS dual-view compound microscope has one 10x widefield and one 16x widefield eyepiece, a forward-facing nosepiece with three DIN achromatic objectives, Brightfield variable-intensity tungsten (incandescent) illumination, a 0.65 NA single-lens condenser, and a mechanical stage. The dual-view monocular viewing head has one eyepiece tube mounted on a fixed 45-degree vertical inclination to reduce eye and neck strain and 360-degree rotation capability to provide a more comprehensive view and enable sharing. The second eyepiece tube is mounted vertically and can accept an eyepiece for use by a second viewer or a camera mount for digital image capture (camera sold separately). The WF10 and WF16x eyepieces have a revolving pointer that is used to identify features for students, or in digital microscopy when taking photographs or displaying images on a whiteboard or projector. The forward-facing revolving nosepiece has 4x, 10x, and 40xS DIN achromatic objectives that provide color correction of magnified images. The 40xS objective is spring loaded to prevent slide damage when focusing. A compound microscope is used for inspection and dissection of specimens when two-dimensional images are desired.The microscope has lower (diascopic) Brightfield illumination that transmits light up through the specimen for enhanced visibility of translucent and transparent objects. Brightfield (BF) illumination allows the specimen to absorb light, resulting in a dark image on a light background. Variable-intensity tungsten (incandescent) illumination provides bright light. The 0.65 NA single-lens condenser and disc diaphragm control the amount of light illuminating the specimen. The mechanical stage locks the slide into place and provides precise slide manipulation along the X- and Y-axis. A stage stop prevents the stage or specimen from coming into contact with the objectives. The solid-metal frame has a stain-resistant enamel finish for durability.SpecificationsHeadCompound dual-view monocularEyepiecesWF10x, WF16xObjectives4X, 10x, 40xS achromaticStageMechanicalLighting configurationTransmitted (lower)CondenserSingle lensDiaphragmDisc diaphragmLight sourceTungsten (incandescent), variable intensityIllumination typeBrightfieldPower110VDimensions15 x 7-1/2 x 5-1/8 inches (H x W x D)Weight10lb.H is height, the vertical distance from the lowest to highest point; W is width, the horizontal distance from left to right; D is depth, the horizontal distance from front to back.Microscopes are instruments used to enhance the resolution of an object or image. Types include compound, stereo, or digital. Compound microscopes use a compound optical system with an objective lens and an eyepiece. Stereo microscopes show object depth in a three-dimensional image. Digital microscopes are used to display an image on a monitor, rather than looking through a lens. Microscopes can have monocular (one), binocular (two), or trinocular (three) eyepieces, with varying magnification abilities. Magnification ability refers to the size of an image. Resolution, also known as resolvant power, refers to the clarity of the image. The interaction between field of view (FOV), numerical aperture (NA), and working distance (WD) determines resolution. Microscopes can control magnification through a fixed focus, or through a range of adjustments. They can also utilize LED, fluorescent, and mirror light sources to help control viewing capabilities. Microscopes are widely used in education, lab research, biology, metallurgy, engineering, chemistry, manufacturing, and in the medical, forensic science, and veterinary industries.United Scope manufactures microscopy equipment and accessories under the brand name AmScope.
