Size:10X Eyepiece, 1X and 2X Objective, 10X and 20X Magnification

The VanGuard 1100SP Series Stereo Microscopes are intermediate-level instruments that have binocular heads with a 360-degree rotation capability and a fixed 45-degree vertical inclination to ease eye strain, -5 to +5 dioptric adjustment capabilities to compensate for the difference in viewing ability between each eye, and 51 to 77mm interpupiliary adjustment for individual eye spacing. The models in this series have 20mm 10x widefield eyepieces that conform to the Deutsches Institut für Normung (DIN) standard; stereo objectives (1x and 2x, 1x and 3x, 2x and 4x, or 1x and 4x); are parfocal and parcentered with revolving turret objectives so that items stay in focus when objectives are rotated; and have a working distance of 102mm. The stage plate is reversible black and white for viewing light or dark samples, and the microscope has two, locked on, stainless steel, spring-loaded stage clips for durability. The microscopes have dual, knurled focus adjustment knobs, for controlled focusing. These units have a rack and pinion assembly, a slip clutch mechanism, and a tension control mechanism to protect the gears. The stand is a solid, stainless steel pole stand with 65mm of total vertical travel ability, and vertical clearance of 65 to 175mm. They are stain-resistant and have a durable cast metal body with an enamel finish, and anti-skid rubber feet. These models come with two eyecups, a dust cover, and instructions. Additional optional eyepieces are sold separately. Stereo microscopes create three-dimensional images and are used for education, biological sciences, and manufacturing applications, among others.

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.

VanGuard 1321BRI Siedentopf Binocular Compound Microscope, WF10x Eyepieces, Infinity Plan Objectives, 40x-1000x Magnification, Brightfield, Kohler, Halogen Illumination, Abbe Condenser, Iris Diaphragm with Blue Filter, Mechanical Stage, 110V Review

VanGuard 1321BRI Siedentopf Binocular Compound Microscope, WF10x Eyepieces, Infinity Plan Objectives, 40x-1000x Magnification, Brightfield, Kohler, Halogen Illumination, Abbe Condenser, Iris Diaphragm with Blue Filter, Mechanical Stage, 110V

The VanGuard 1320BRI Siedentopf Binocular Compound Microscope has a pair of 10x widefield high-eyepoint eyepieces, a reverse-mounted nosepiece with four DIN infinity plan achromatic objectives, Kohler halogen illumination, nested coarse and fine focus, a 1.25 NA Abbe condenser with iris diaphragm and blue filter, and a mechanical stage. The Siedentopf binocular head has a pair of eyepieces with interpupillary adjustment, a fixed inclination to reduce eye and neck strain, and 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 refocus the image. High-eyepoint eyepieces ease viewing for viewers wearing glasses. Dioptric adjustment accommodates individual eye-strength differences. Infinity plan objectives provide focus over the entire range of the viewing field, and a longer working distance for improved focus when auxiliary components are utilized. Achromatic objectives provide color correction of magnified images. 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 lower (diascopic) brightfield, Kohler 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. Kohler illumination focuses and centers the light path using two iris diaphragms, providing optimum contrast and resolution. The halogen light source provides bright light in a concentrated path, and a rheostat controls the amount of light emanating from the lamp. It has an Abbe condenser that can be adjusted to control the distance of the light from the stage, an iris diaphragm to optimize the amount of light illuminating the specimen, and a blue filter to help naturalize the light. The condenser is controlled using a rack-and-pinion mechanism. The mechanical stage locks the slide into place and provides precise slide manipulation along the X- and Y-axes. Coaxial coarse and fine focus knobs are nested to speed focusing for left-and right-handed viewers, and tension adjustment ensures specimen stays focused during viewing. The frame has a stain-resistant enamel finish.

Size:With Trinocular Head, Halogen Illumination, Achromatic Phase Type

The VanGuard 1232CM clinical microscope with phase contrast has trinocular viewing heads, Brightfield viewing, achromatic objectives, and magnification abilities of 10X, 20X, 40X, and 100X (oil immersion method) for a variety of resolvant options. This microscope enhances object or image resolution, and is commonly used for research and professional applications in medical and veterinary clinics, universities and industrial laboratories.

This microscope features a trinocular viewing configuration with two heads to ease eye strain and provide a more comprehensive view, and a third head to connect to an external monitor or a camera, for an alternative viewing option. The binocular heads have a fixed, 30-degree vertical inclination, and 360-degree rotation capabilities. The microscope has a 20/80 light split, which means that when the third head is used, 20% of the light goes to the third head, and 80% goes to the user’s eyes through the binocular heads. It has 55-75mm interpupillary adjustment for individual eye spacing, and – 5 to + 5 dioptric adjustment capabilities to compensate for the difference in viewing ability between each eye. Two heads have rubber eyepieces to block out external light interference. This microscope features Deutsches Institut für Normung (DIN)-standard achromatic objective lenses, which correct for red and yellow chromatic aberrations. Adjustable resolution provides DIN-standard magnification options of 10X (0.25 NA), 20X (0.40 NA), 40X (0.60 NA), and 100X (1.25 NA). Brightfield illumination controls light from below, allowing a specimen to absorb light for clear illumination. The microscope uses phase contrast to produce clearer images of opaque or unstained objects. Integrated Koehler illumination provides brightness control, and achromatic lenses correct for red and yellow chromatic aberrations. The unit adjusts light through an iris diaphragm, and has a 1.25 numerical aperture (NA) Abbe condenser for high resolution, with rack and pinion focusing control. It has 20-watt variable quartz halogen lighting, and a filter holder located on the collector.

The rectangular, chemical-resistant mechanical stage has a drop-down, right-hand, X-Y rack and pinion control. The stage has a removable, spring-clip slide holder mechanism for specimen maneuverability, and a cross-travel range of 75 x 50mm. The microscope has coaxial coarse- and fine-focus adjustment controls with tension adjustment and an auto-stop mechanism to protect slides. It has a slip clutch mechanism, and a tension control mechanism for gear protection. The reverse-pitch nosepiece has secure, positive stops, and four rotation positions support a range of magnification. The microscope has a stain-resistant and durable cast metal body with an enamel finish, and anti-skid rubber feet to prevent slipping. It comes with a clear diffusing filter, a blue filter, a green filter, a telescoping eyepiece, spare lamps and fuses, a dust cover, two rubber eyecups, a six-foot power cord, and instructions.
