The AmScope T340A-DK-LED compound trinocular microscope has interchangeable pairs of 10x widefield and 16x widefield eyepieces, a reverse-mounted nosepiece with four DIN achromatic objectives, Brightfield/Darkfield (BF/DF) LED illumination, and a double-layer mechanical stage. The vertical trinocular port can be used as a C-Mount or 23mm photo port (camera sold separately). The Siedentopf binocular head has 48 to 75mm inter-pupillary adjustment, fixed 30-degree vertical inclination to reduce eye and neck strain, and 360-degree rotation capability to provide a more comprehensive view and enable sharing. Bilateral dioptric adjustment accommodates individual eye-strength differences. The reverse-mounted nosepiece has 4x, 10x, 40xS (spring), and 100xS (spring, oil) DIN achromatic objectives that combine with the eyepieces to provide color correction of magnified images. The 40xS objective is spring loaded to prevent slide damage when focusing. The 100xS spring-loaded oil objective provides increased resolution over a standard objective. A reverse-mounted nosepiece keeps objectives out of the way to prevent damage and contamination, and to enable more secure slide handling. A compound microscope is used for inspection and dissection of specimens when two-dimensional images are desired.

The microscope has Brightfield/Darkfield (BF/DF) illumination. Brightfield (BF) illumination allows the specimen to absorb light, resulting in a dark image on a light background, and Darkfield (DF) illumination reflects light off the specimen, resulting in a light image on a dark background. LED illumination provides bright, cool light for working with temperature-sensitive or live specimens. The 1.25 NA 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 0.7 to 0.9 NA darkfield condenser blocks the central portion of the light path to produce
