About VanGuard 1220CM-BP Brightfield Clinical Microscope
The Van Guard 1220CM-BP clinical microscope has binocular viewing heads, Brightfield configuration, and a magnification ability of 4X, 10X, 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 binocular viewing heads with fixed 30-degree vertical inclination, and 360-degree rotation. It has 55-75 mm interpupillary adjustment for individual eye spacing, and - 5 to + 5 dioptric adjustment capabilities to compensate for the difference in viewing abilities between each eye. The 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 resolvant options of 4X, 10X, 40X, and 100X (0.10, 0.25, 0.60, 1.25 numerical aperture [NA]). 10X widefield eyepiece magnification, and an 18 mm eyepiece field diameter provide a range of application abilities. Its optical system is fixed at 160 mm. Brightfield illumination controls light from below, allowing a specimen to absorb light for clear illumination. The unit adjusts light through an iris diaphragm, and has a 1.25 NA Abbe condenser for higher resolution. It has 20-watt variable quartz halogen lighting, and a filter holder located on the collector. The 1220CM-BP has a 10X widefield eyepiece magnifier, which locks on to the unit for ease of operation, and provides an 18 mm field diameter. The rectangular, chemical-resistant mechanical stage has drop-down, right-hand, rack and pinion, X-Y control. It has a removable, spring-clip slide holder mechanism for specimen maneuverability, and a cross-travel range of 70 x 30 mm. The stage has a removable spring-clip slide holder for object maneuverability. This microscope has coaxial coarse- and fine-focus adjustment controls with tension adjustment, and an auto-stop mechanism to protect the gears. Focus range is 40mm, with 0.002 mm precision. 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, ergonomic body with an enamel finish, and anti-skid rubber feet to prevent slipping. It comes with a clear diffusing filter, a blue filter, spare lamps and fuses, a dust cover, two rubber eyecups, and an operation manual. The 1220CM-BP has five-year mechanical and optical warranties, and a one-year electrical warranty. The 1220CM-BP microscope overall dimensions are 380 x 210 x 180 mm (H x W x D), and base dimensions are 210 x 180 mm (W x D). The unit weighs 5.5 kg. It works with a 1A, 250 volt fuse (included), and a 110-volt power source for illumination, and comes with a six-foot power cord. 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 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. 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 use LED, fluorescent, and mirror light s
