VanGuard Bright Field Phase Contrast Clinical Microscope W/ Trinocular Head Halogen Illumination Magnification 360 Degree Viewing Angle

Brand: VANGUARD

Features:

• Compound clinical microscope for high magnification in diagnostic and educational applications; frequently used in medical and veterinary clinics, universities, and industrial laboratories
• Trinocular viewing configuration, with two eyepieces to ease eye strain and provide a more comprehensive view, and a third head to connect to an external monitor or camera
• Magnification ability of 10X (0.25 NA), 20X (0.40 NA), 40X (0.60 NA), and 100X (1.25 NA), for a variety of applications
• Brightfield, darkfield, and phase contrast illumination configurations allow a specimen to absorb light from below for clear illumination, enhance contrast, and produce clearer images of opaque or unstained objects
• Plan achromatic lenses correct for red and yellow chromatic aberrations and sharpen images

Details: The VanGuard 1433PHi clinical microscope has a trinocular viewing configuration, Brightfield, darkfield and phase contrast configurations, integrated Koehler illumination, plan achromatic objectives, and magnification abilities of 10X, 20X, 40X, and 100X (oil immersion method), for a variety of applications. This compound microscope enhances object or image resolution, and is commonly used in demanding applications, including diagnostic and educational uses in medical and veterinary clinics, universities and industrial laboratories. The microscope has a trinocular viewing configuration, with two eyepieces to ease eye strain and provide a more comprehensive view, and a third head to connect to an external monitor or camera for an alternative viewing option. The microscope has a 20/80 light split, which means that when a third head is used, 20% of the light goes through the third head, and 80% goes to the user’s eyes through the binocular heads. The unit has 55-75mm interpupillary adjustment for individual eye spacing, and - 6 to + 6 dioptric adjustment capabilities, to compensate for the difference in viewing ability between each eye. It has a VanGuard infinity-corrected optical system (VIOS) for clear images. The microscope has Deutsches Institut für Normung (DIN)-standard plan achromatic objective lenses, which correct for red and yellow chromatic aberrations, and sharpen images. Adjustable resolution provides resolvant options of 10X (0.25 NA), 20X (0.40 NA), 40X (0.60 NA), and 100X (1.25 NA) (oil immersion method). Integrated Koehler illumination controls brightness, and Brightfield configuration controls light from below, allowing a specimen to absorb light for clear illumination. Darkfield and phase contrast illumination configurations enhance contrast, and produce clearer images of opaque or unstained objects. The unit adjusts light through a 1.25 numerical aperture (NA) Abbe condenser with an iris diaphragm. A Zernike phase annuli condenser has 10X, 20X, 40X, and 100X objectives. The condenser is mounted on a rack and pinion focusing mechanism, 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 magnifier, which locks on to the unit for ease of operation. The eyepieces have a high eyepoint (20mm field diameter), and rubber eyecups to block out external light interference. This microscope has a large base, and a full-size, ergonomic frame. It is designed for durability, and to provide support for a variety of demanding laboratory uses. The unit has a rectangular, chemical-resistant, mechanical stage with a rack and pinion assembly, and an X-Y, right-hand, drop-down control. It has a removable, spring-clip slide holder mechanism for specimen maneuverability, and a cross travel range of 75 x 50mm. A coaxial, low-position mechanism controls focus motion. The unit has coarse- and fine-focus adjustment controls with a 40mm focusing range, and 0.002mm precision. Auto-stop and tension control mechanisms protect the gears. The reverse-pitch nosepiece has secure, positive stops, and five 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. It comes with a clear diffusing filter, a blue filter, a green filter, a telescoping eyepiece, a spare lamp and fuse, a dust cover, a six-foot power cord, and instructions.
