The BestScope BS-3020T Trinocular Stereo Zoom Microscope has a pair of 10x extra-widefield eyepieces, a trinocular port, a 1x to 4.5x zoom objective for 10x to 45x continuous magnification, upper and lower LED illumination, coaxial focus, and a fixed stage. The trinocular viewing head has a binocular head with a pair of eyepieces with interpupillary adjustment and a fixed inclination to reduce eye and neck strain, and a trinocular port that accepts a camera adapter (sold separately). The zoom objective provides low magnification and a longer focal length for inspecting large-scale specimens, or specimens that require hands-on manipulation or repair, including rocks, minerals, watches, or circuit boards. A stereo zoom microscope is used for inspection and dissection of specimens when three-dimensional images are desired, and provides zoom, sometimes called pancratic, magnification that allows the user to zoom in on the specimen within a continuous magnification range.

The microscope has upper (episcopic) illumination that reflects light off the specimen for enhanced visibility of opaque specimens and lower (diascopic) illumination that transmits light up through the specimen for enhanced visibility of translucent and transparent objects. Coaxial focus eases focusing for left- and right-handed viewers. The LED light sources provide bright, cool light for working with temperature-sensitive or live specimens.

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.

BestScope International Ltd. manufactures microscopes, digital cameras, and accessories for education, inspection, research, and clinical and industrial applications. The company, founded in 1995, is headquartered in Beijing, China.

  • Double-layer mechanical stage with 1mm stage divisions and stage stop; graduated coarse and fine focus with tension control to prevent stage drift

The AmScope T490B-10MA digital compound trinocular microscope has a sliding head, interchangeable pairs of 10x and 20x widefield eyepieces, a forward-facing nosepiece with four DIN achromatic objectives, Brightfield halogen illumination, and a double-layer mechanical stage with a stage stop to protect slides and objectives from damage. The 10.7MP camera has a CMOS color sensor, a reduction lens, image capture and editing software, and USB 2.0 output to capture or display still or video images on a computer or projector. The trinocular viewing head has a vertical camera mount and a compensation-free binocular viewing head with interchangeable pairs of WF10x and WF20x eyepieces and sliding head to adjust inter-pupillary distance, 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. A Siedentopf binocular head enables the viewer to change the interpupillary distance without changing the tube length, eliminating the need to re-focus the image. It has an interpupillary range of 55 to 75mm to accommodate individual eye differences, and bi-lateral dioptric adjustment accommodates individual eye-strength differences. The vertical trinocular port accepts a camera with a 23mm or C-Mount adapter. The forward-facing nosepiece has 4x, 10x, 40xS (spring), and 100xS (spring, oil) DIN achromatic optical-glass 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-immersion objective uses oil between the specimen and the objective lens to provide 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 10.7MP digital camera has a CMOS color sensor for displaying still microscopy images and streaming live videos to a computer or projector. The camera has 40x magnification and a built-in 0.5x reduction lens that ensures that the display has a similar field of view as the microscope eyepiece. The camera can be mounted in a C/CS-Mount or any 23mm eye tube. The camera includes image capture and editing software that provides still image and live video capture and editing. Measurement functions including length, area, and angle. The software supports JPEG, BMP, TIFF and RAW, and is compatible with Windows (32- and 64-bit XP, Vista, 7, and 8), and Mac OS X (32-bit). Camera drivers are compatible with Windows (XP, Vista, 7, and 8), Mac OS X, and Linux. The camera has a USB 2.0 data port (cable included).

The microscope has lower (transmitted, 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. Halogen illumination provides bright light in a concentrated path and has a rheostat to control light intensity. 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 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 from coming into contact with the slide and objectives. The stage is 5-1/2 x 5-1/2 inches (140 x 140mm) and has a traveling range of 2-15/16 x 1-3/4 inches (75 x 45mm). 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 solid-metal 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.
