C & A Scientific Premiere MF-02 Binocular Compound Microscope, WF10x Eyepieces, 40x-1000x Magnification, Brightfield, Fluorescent Illumination, Iris Diaphragm, Mechanical Stage, 110V

The C & A Scientific Premiere MF-02 Binocular Compound Microscope has a pair of 10x widefield eyepieces, a forward-facing nosepiece with four DIN achromatic objectives that are parcentered and parfocal, fluorescent illumination, separate coarse and fine focus, a 1.25 NA condenser, and a mechanical stage. The binocular head has fixed inclination to reduce eye and neck strain, 360-degree rotation capability to provide a more comprehensive view, and diopter adjustment to accommodate individual eye-strength. Achromatic objectives provide color correction of magnified images. Parcentered and parfocal objectives ensure that the image stays centered and focused when the magnification is changed. A forward-facing nosepiece eases changing objectives. The 40xR and 100xR objectives are retractable and spring-loaded to prevent damage to the slide or objective when focusing. The 100xR objective is also an oil objective that 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. The fluorescent light source provides cool, white light for observing specimens as they would appear in their natural environment, and has an iris diaphragm to optimize the amount of light illuminating the specimen. The condenser is controlled using a spiral mechanism. The mechanical stage locks the slide into place and provides precise slide manipulation along the X- and Y-axes. A stage stop prevents the stage or specimen from coming into contact with the objectives. Separate coarse and fine focus knobs speed focusing. A tension adjustment ensures specimen stays focused during viewing, and a slip clutch prevents excess pressure from damaging the slides or objectives.

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.
