Manufacturer Description

The Motic 1100100500592 Series B3-220 ASC Siedentopf Binocular Compound Microscope has a pair of 10x widefield eyepieces, a reverse-mounted nosepiece with four DIN high-contrast objectives, Kohler halogen illumination, nested coarse and fine focus, a 1.25 NA Abbe condenser with iris diaphragm, and a mechanical stage. The Siedentopf binocular head has a pair of eyepieces with interpupillary adjustment, a fixed inclination to reduce eye and neck strain, and rotation capability to provide a more comprehensive view and enable sharing. A Siedentopf binocular head enables the viewer to change the interpupillary distance without changing the tube length, eliminating the need to refocus the image. Dioptric adjustment on the left eyepiece accommodates individual eye-strength differences. A reverse-mounted nosepiece keeps objectives out of the way to prevent damage and contamination, and to enable more secure slide handling. Rotation positions with secure, positive stops ensure accurate positioning and support a range of magnification options. ASC (achromatic super contrast) high-contrast objectives provide sharp color distinction. The 40xS and 100xS objectives are retractable and spring-loaded to prevent damage to the slide or objective when focusing. The 100xS 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, Kohler 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. Kohler illumination focuses and centers the light path using two iris diaphragms, providing optimum contrast and resolution. The halogen light source provides bright light in a concentrated path, and a rheostat controls the amount of light emanating from the lamp. The 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. Blue, green, and yellow filters are included to modify the light to suit various specimens. The mechanical stage locks the slide into place and provides precise slide manipulation along the X- and Y-axes. Coaxial coarse and fine focus knobs are nested to speed focusing for left-and right-handed viewers, and tension adjustment ensures specimen stays focused during viewing. A stage stop prevents the stage or specimen from coming into contact with the objectives.

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.

Motic manufactures microscopes, microscope cameras, digital imaging products, and application software. The company, founded in 1988 and headquartered in Xiamen, China, is a subsidiary of Hong Kong-based Speed Fair Co. Ltd. and meets International Organization for Standardization (ISO) standards 9001 and 14000.
