AmScope T600A-PCT-DK Professional Phase-Contrast Compound Trinocular Microscope, WF10x and WF16x Eyepieces, 40X-1600X Magnification, Brightfield/Darkfield, Halogen Illumination, Abbe Condenser, Double-Layer Mechanical Stage, Anti-Mold, 110V, Includes 4 Ph

The AmScope T600A-PCT-DK compound trinocular microscope has a Siedentopf binocular mount with interchangeable pairs of 10x widefield and 16x widefield eyepieces, a reverse-mounted nosepiece with four DIN achromatic high-resolution objectives, Brightfield/Darkfield/phase-contrast halogen illumination, a double-layer mechanical stage with a stage stop to protect slides and objectives from damage, and anti-mold surfaces to preserve optics in high-humidity areas. The trinocular head has a vertical camera mount and a Siedentopf binocular mount with interchangeable pairs of WF10x and WF16x eyepieces with 55 to 75mm Siedentopf interpupillary adjustment, a fixed 30-degree vertical inclination to reduce eye and neck strain, and a 360-degree rotation capability to provide a more comprehensive view and enable sharing. Dioptric adjustment accommodates individual eye-strength differences. The vertical trinocular port accepts a camera with a 23mm or C-Mount adapter (camera sold separately). The mechanical tube length is 6-5/16" (160mm).The reverse-mounted revolving nosepiece has 4x, 10x, 40xS, and 100xS (oil) DIN achromatic high-resolution objectives that provide color correction of magnified images. The 40xS objective is spring loaded to prevent slide damage when focusing. The 100xS spring-loaded oil-immersion objective uses oil between the specimen and the objective lens to provide increased resolution over a standard objective. Four plan phase-contrast objectives (10x, 20x, 40x, and 100x) and corresponding condensers provide high-contrast images. Plan objectives provide improved focus over the entire range of the viewing field. The turret eases magnification changes. A compound microscope is used for inspection and dissection of specimens when two-dimensional images are desired.

The microscope has Brightfield/Darkfield (BF/DF) and phase-contrast 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. Phase-contrast provides high contrast and visibility without the use of stains, allowing specimens to be observed in their natural state without being killed or fixed. Halogen illumination provides bright light in a concentrated path. The 1.25 NA Abbe condenser is mounted on a rack-and-pinion control system, 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 graduated double-layer mechanical stage, with 1mm stage divisions, locks the slide into place and provides precise slide manipulation along the X- and Y-axis to allow coordinates to be recorded, enabling the viewer to return to a specific location on the slide. A stage stop prevents the stage or specimen from coming into contact with the objectives. The stage is 5-1/2 x 6-5/16 inches (140 x 160mm) and has a traveling range of 2-3/4 x 2 inches (70 x 50mm). Graduated coaxial coarse and fine focus has a focusing range of 1-3/16" (30mm) and fine-focus divisions of 0.002mm (0.0000787") that enable measurements to be taken. Focus knob tension control prevents the stage from drifting out of focus. The cast-alloy enamel-coated body is durable and resistant to stains and corrosion.

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.

United Scope manufactures microscopy equipment and accessories under the brand name AmScope. The company, founded in 1996, is headquartered in Irvine, CA.
