The Thomas 1100400800111T Digital Binocular Compound Microscope has a pair of 10x widefield eyepieces, a forward-facing nosepiece with four high-contrast objectives, halogen illumination, nested coarse and fine focus, 1.25 NA Abbe condenser with iris diaphragm, and a mechanical stage. The digital and analog camera captures and displays images on a computer or projector (sold separately). The binocular viewing head has a fixed inclination to reduce eye and neck strain. A forward-facing nosepiece eases changing objectives. 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 digital compound microscope is used for inspection and dissection of specimens when two-dimensional images are desired, and where image capture, detailed records, or documentation is required.
The digital and analog camera has a CCD color sensor for displaying still microscopy images and streaming live videos to a computer or projector. It includes image capture and editing software that provides still image and live video capture and editing capability, including measurement functions. The software supports the Motic SFC file format and is compatible with Windows XP and above, and Mac OS X. The camera has USB 2.0, S-video, and RCA outputs.
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. 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-axis. 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 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.
