VanGuard 1421BRI Brightfield Clinical Microscope with Binocular Headc Halogen Illuminationc 4Xc 10Xc 40Xc 100X Magnificationc 360 Degree Viewing Anglec VIOS Infinity-Corrected Optical System

The Van Guard 1421BRi clinical microscope has binocular viewing headsc Brightfield configurationc integrated Koehler illuminationc plan achromatic objectivesc and magnification abilities of 4Xc 10Xc 40Xc and 100Xc (oil immersion method) for a variety of applications. This compound microscope enhances object or image resolutionc and is commonly used in demanding applicationsc including diagnostic and educational uses in medical and veterinary clinicsc universitiesc and industrial laboratories. This microscope features binocular viewing headsc to ease eye strain and to provide a more comprehensive view. The unit has 55-75 mm interpupillary adjustment for individual eye spacingc and - 6 to + 6 dioptric adjustment capabilities to compensate for the difference in viewing ability between each eye. Its optical system is fixed at 160 mm. The microscope has Deutsches Institut für Normung (DIN)-standard plan achromatic objective lensesc which correct for red and yellow chromatic aberrationsc and sharpen images. Adjustable resolution provides resolvant options of 4Xc 10Xc 40Xc and 100X (0.10c 0.25c 0.65c 1.25 numerical aperture NA) (oil immersion method). Integrated Koehler illumination controls brightnessc and brightfield configuration controls light from belowc allowing a specimen to absorb light for clear illumination. The unit adjusts light through a 1.25 NA Abbe condenser with an iris diaphragm. The condenser is mounted on a rack and pinion focusing mechanismc and the unit has a filter holder on the collector. The unit has 20-watt variable quartz halogen lighting. It has a 10X widefield eyepiece magnifierc which locks on to the unit for ease of operation. The eyepieces have a high eyepoint (20 mm field diameter)c and rubber eyecups to block out external light interference. This microscope has a large base of 260 x 170 mm (W x D)c and a full-sizec ergonomic frame. The microscope is designed for durabilityc and to provide support for a variety of demanding laboratory uses. The unit has a rectangularc chemical-resistantc mechanical stage with rack and pinion assembly and an X-Yc right-handc drop-down control. It has a removablec spring-clip slide holder mechanism for specimen maneuverabilityc and a cross travel range of 75 x 50 mm (W x D). Stage dimensions are 160 x 140 mm (W x D). A coaxialc low-position mechanism controls focus motion. The unit has coarse- and fine-focus adjustment controls with a 40 mm focusing rangec and 0.002 mm precision. Auto-stop and tension control mechanisms protect the gears. The reverse-pitch nosepiece has securec positive stopsc and five rotation positions support a range of magnification. The microscope has a stain-resistance and durable cast metal body with an enamel finishc and anti-skid rubber feet. It comes with a clear diffusing filterc a blue filterc a spare lamp and fusec a dust coverc and instructions. The 1421BRi has five-year mechanical and optical warrantiesc and a one-year electrical warranty. The 1421BRi microscope overall dimensions are 425 x 220 x 380 mm (H x W x D)c and base dimensions are 170 x 260 mm (W x D). The unit weighs 9.0 kg. It works with a 0.50Ac 250-volt fusec and a 110-volt power source for illuminationc and comes with a six-foot power cord. Microscopes are instruments used to enhance the resolution of an object or image. Types include compoundc stereoc 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 monitorc rather than looking through a lens. Microscopes can have monocular (one)c binocular (two)c or trinocular (three) eyepiecesc with varying viewing abilities. A trinocular eyepiece is used to output digital images to an internal or external device such as a camera or monitor. Magnification ability refers to the size of an image. Resolutionc also known as resolvant powerc refers to the clarity of the image. The interaction between field of view (FOV)c numerical aperture (NA)c and working distance (WD) determines resolution. Microscopes can control magnification through a fixed focusc or through a range of adjustments. They can also use LEDc fluorescentc and mirror light sources to help control viewing capabilities. Microscopes are widely used in educationc lab researchc biologyc metallurgyc engineeringc chemistryc manufacturingc and in the medicalc forensic sciencec and veterinary industries. Vee Gee Scientific manufactures laboratory equipment and suppliesc and makes the VanGuard brand of products. The companyc founded in 1981 and headquartered in Kirklandc WAc offers scientific equipment for educationalc researchc clinicalc and industrial applications. What’s in the Box
