About Motic 1100100401211 Series BA210 Basic Siedentopf
The Motic 1100100401211 Series BA210 Basic Siedentopf Binocular Compound Microscope has a pair of 10x widefield high-eyepoint eyepieces, a reverse-mounted nosepiece with four color-corrected infinity optical system (CCIS) EF-N plan achromatic objectives, 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. High-eyepoint eyepieces ease viewing for viewers wearing glasses. Dioptric adjustment 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. CCIS EF-N plan achromatic objectives provide color correction and focus over the entire range of the viewing field, have a longer working distance for improved focus when auxiliary components are utilized, and have a multi-layer coating to enhance contrast. The 40xS and 100xS objectives are spring-loaded objectives that retract when they come into contact with the stage or slide, preventing slide damage when focusing. The 100xS objective is also an oil objective that provides increased resolution over a standard objective. A basic compound microscope is used in classroom, home school, and hobbyist settings 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 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, has an iris diaphragm to optimize the amount of light illuminating the specimen, and has a slider slot to accept a phase or darkfield slider (sliders sold separately). A collector lens assembly holds the included blue filter that helps naturalize the light. 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.

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 throug
