AmScope D120C-MS Dual-View Compound Monocular Microscope, WF10x and WF25x Objectives, 40X-2500X Magnification, Brightfield, 1.25 NA Abbe Condenser, Mechanical Stage
The AmScope D120C-MS dual-view compound microscope has one 10x widefield and one 25x widefield eyepiece, a forward-facing nosepiece with four DIN achromatic objectives, Brightfield variable-intensity tungsten (incandescent) illumination, a 1.25 NA Abbe 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 (eyepiece and camera sold separately). Dioptric adjustment on upright tube accommodates individual eye-strength differences. The WF10x and WF25x 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, 40xS, and 100xS (oil) DIN achromatic objectives that provide color correction of magnified images. The 40xS objective is spring loaded to prevent slide damage when focusing. The 100xS spring-loaded oil objective provides increased resolution over a standard objective. 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 1.25 NA Abbe condenser can be adjusted to control the distance of the light from the stage and has an iris diaphragm to optimize 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, and a stage stop prevents the stage or specimen from coming into contact with the objectives. Separate coarse and fine focus on rack-and-pinion mount provides precise focus, and tension adjustment ensures specimen stays focused during viewing. The solid-metal frame has a stain-resistant enamel finish for durability.

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.
