The Motic 1100100500333 Series B1-223 ASC Trinocular Compound Microscope has a pair of 10x widefield eyepieces, a trinocular port, a forward-facing nosepiece with four high-contrast objectives, halogen illumination, coaxial nested coarse and fine focus, 1.25 NA Abbe condenser with iris diaphragm, and a mechanical stage. The trinocular viewing head has a binocular head with a pair of eyepieces that slide to adjust interpupillary distance, a fixed inclination to reduce eye and neck strain, and 360-degree rotation capability to provide a more comprehensive view and enable sharing; and a trinocular port that accepts a camera adapter (sold separately). 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 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 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. The condenser is controlled using a rack-and-pinion mechanism. 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 sli
