  • Trinocular compound microscope provides high magnification for biological use and educational applications
  • Siedentopf trinocular head with interchangeable pairs of 10x widefield and 16x widefield eyepieces with 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
  • Reverse-mounted nosepiece with 4x, 10x, 40xS (spring), and 100xS (spring, oil) DIN achromatic objectives that provide color correction of magnified images
  • Brightfield and dry darkfield, LED illumination, 1.25 NA Abbe condenser with iris diaphragm for clear examination and light control, and dry darkfield condenser with 0.7 to 0.8 NA
  • Double-layer mechanical stage, with 1.0mm stage divisions, locks 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

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 a darkfield image. The 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. Graduated coaxial focus control allows measurements to be taken. The enamel-coated cast-steel 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.

AmScope 3.5X-45X Simul-Focal Stereo Zoom Microscope on Dual Arm Boom Stand with 144-LED Ring Light Review

AmScope 3.5X-45X Simul-Focal Stereo Zoom Microscope on Dual Arm Boom Stand with 144-LED Ring Light

This microscope features a unique simul-focal optical system with an adjustable trinocular port to enable well-focused clear images on your computer/video screen while simultaneously obtaining sharp, focused images through the eyepieces. Most trinocular microscopes allow you to view either through the trinocular port or the eyepieces only, forcing you to switch between the two. Since these trinocular ports are not simul-focal with the rest of the microscope optical system, you have to re-focus the microscope after each switch. This microscope, however, erases this step by providing simul-focal viewing. Especially convenient for quality-control inspections, teaching demonstrations, and many other industry applications, your colleagues or students can simultaneously view clear images shown through the trinocular port while you work through the eyepieces.

This microscope comes with a simul-focal trinocular head, a pair of super widefield high-eyepoint 10X eyepieces, a double-arm heavy-duty boom stand, and a 144 LED ring-light. This microscope offers high resolution, crystal clear images, large magnifying zoom range, and long working distance. The 45-degree inclined trinocular head and high-eyepoint design ensures comfortable observation, including eyeglass wearers. In addition, the rubber eye-guards provide further comfort. The trinocular port also allows the ability to add photographic or video capability. The double-arm boom stand lets the user manipulate the microscope head around three different axes (x, y, and z) and to maneuver the microscope head in any direction desired. The 144-LED ring-light provides fixed, even and cool illumination. It is an ideal instrument for anyone in the semiconductor and electronics industries, research labs, gemology, engraving, and serious collecting.

  • Tele Vue 2x Barlow Lens, 1.25″.

Tele Vue Barlows: “An Optically Perfect Window” Properly designed Barlows do wonderful things. First, they amplify power while retaining the eyepiece’s eye-relief. Second, they slow the telescope’s f/#, which improves eyepiece sharpness. Third, the designer can introduce compensations for eyepiece aberrations. Tele Vue’s 1 1/4″ 2x and 3x Barlows were envisioned as magnification windows. Multi-coated high index glasses assure optimum aberration correction, exceptional contrast and virtually no light loss. Tele Vue Barlows achieve their design goals even when tested by the fastest scopes. The Tele Vue design approach includes mechanical conveniences. The Barlows are parfocal with Tele Vue eyepieces. The 2X Barlow is threaded for 1 1/4″ filters.

Our AstroView 120ST is a compact, rich-field refractor designed for observation of nebular clouds, star clusters, and even galaxies. Its multi-coated achromatic objective lens has a 120mm (4.7″) clear aperture and has a focal length of just 600mm (f/5). Compared to our standard 120mm AstroView (f/8.3), that translates to a 66% wider field of view for any given eyepiece. The fast f/5 optical system also makes it an excellent telescope for astrophotography. The 120ST has a well-baffled optical tube to ensure good contrast. The cast-metal, 2″ rack-and-pinion focuser accommodates either both 1.25″ and 2″ diagonals. The AstroView equatorial mount with adjustable aluminum tripod provides a sturdy platform for precision tracking. Add an optional EQ-3M electronic drive for fully automatic tracking. One-year limited warranty.
