The Van Guard 1486FLi compound microscope has a trinocular viewing configuration, and features fluorescent illumination for high ultraviolet (UV) transmission, with Brightfield, phase contrast illumination techniques, an Abbe 1.25 NA condenser, and magnification abilities of 4X (0.10 NA), 10X (0.25 NA), 20X (0.40 NA), 40X (0.60 NA), and 100X (1.25 NA) (oil immersion method). This compound microscope enhances object or image resolution, produces fluorescence images with clarity, and it is commonly found in research and clinical applications.

This microscope features a VanGuard infinity-corrected optical system (VIOS) for clear images. It features fluorescence, Brightfield, and phase contrast illumination techniques which control light from below, allowing a specimen to soak up light for clear illumination, luminesce for top ultraviolet (UV) transmission, and convey clearer images of opaque or unstained objects. A Brightfield, 1.25 numerical aperture (N.A.) Abbe condenser with an iris diaphragm adjusts light. Adjustable resolution provides Deutsches Institut für Normung (DIN)-standard, coated objective options of 4X (0.10 NA), 10X (0.25 NA), 40X (0.60 NA) and 100X (1.25 NA) (oil immersion method). Phase contrast has a 1.25 N.A. Zemike condenser having an iris diaphragm to adjust light diameter, and provide higher resolution. The condenser has an outward-swinging filter holder, dispersion, and blue and green fluorescence filters. Adjustable resolution provides coated DIN-standard magnification options of 10X (0.25 NA), 20X (0.40 NA), 40X (0.60 NA), and 100X (1.25 NA) (oil immersion method). Condensers are mounted on the rack and pinion focusing mechanism. Plan achromatic objectives correct for red and yellow chromatic aberrations, and sharpen images. This microscope has 100-watt HBO (mercury, luminescence, unforced cooling) mercury-reflected illumination, and 20-watt variable quartz halogen transmission lighting.

The 1486FLi has a 10X widefield eyepiece magnifier, which locks on on the unit for easy operation, and offers an 18 mm field diameter. It has coaxial coarse- and fine-focus controls with tension adjustment, with an auto-stop feature to prevent damage on the plate or objectives. It includes a 40 mm focus range with 0.002 mm precision. The microscope includes a trinocular viewing configuration, with two eyepieces to ease eye strain and supply an even more comprehensive view, as well as a third head to connect for an external monitor or camera on an alternative viewing option. The binocular eyepieces are fixed vertically at 30 degrees, and rotate 360 degrees. The microscope has a 20/80 light split, this means that when a third head is used, 20% with the light goes with the third head, and 80% goes towards the user’s eyes over the binocular heads. It has 55-75mm interpupillary adjustment for individual eye spacing, and - 6 to + 6 dioptric adjustment capabilities, to pay for the difference in viewing ability in between each eye.

The rectangular, chemical-resistant, drop-down, mechanical stage comes with an X-Y control with rack and pinion drive, and right-hand coaxial control. It has a cross-travel array of 75 x 50 mm (W x D), measures 160 x 140 mm (W x D), also it features a removable spring clip. Stage motion has right-hand, coaxial control plus a rack and pinion drive for support. The ball-bearing nosepiece is made with high-grade lubricant, and contains secure, positive stops. It has five rotation positions to support a variety of magnification, and it is reversed (inward-facing) to permit slide manipulation, and to help keep the objectives clean. The microscope features a stain-resistant and sturdy cast metal body with the enamel finish, and anti-skid rubber feet. The large, ergonomic frame is made for frequent and demanding use. The unit comes having a dispersion filter, a blue filter, a green filter, a telescoping eyepiece, an additional 20-watt halogen lamp, two spare 0.25A, 250-volt fuses, two spare 8.0A, 250-volt fuses, a dust cover, and instructions. The 1486FLi has five-year mechanical and optical warranties, as well as a one-year electrical warranty.

The 1486FLi microscope overall dimensions are 465 x 160 x 225 mm (H x W x D), and base dimensions are 160 x 225 mm (W x D). Stage dimensions are 160 x 140 mm (W x D). The unit weighs 10.7 kg. Blue broadband fluorescence filter specifications are: excitation 430-490nm, emission 520+ nm, dichrotic 500nm, intended dyes FITC, Acridine Orange and Auramine. Green broadband fluorescence filter specifications are: excitation 480-550nm, emission 590+ nm, dichrotic 570nm, intended dyes ethidium bromide & TRITIC. Brightfield, fluorescence, achromatic objective specifications are: 4X has 0.10 NA, 17.0mm working distance (WD), and 4.5mm field of vision (FOV); 10X: 0.25 NA, 8.0mm WD, 1.8 FOV; 40X: 0.65 NA, 0.40mm WD, 0.45mm FOV; 100X: 1.25 NA, 0.25mm WD, 0.18 FOV. Phase contrast, plan achromatic objective specifications are: 10X: 0.25 NA, 8.0mm WD, 1.8mm FOV; 20X: 0.40 NA, 0.50mm WD, 0.9mm FOV; 40X: 0.65 NA, 0.40mm WD, 0.45mm FOV; 100X: 1.25 NA, 0.25mm WD, 0.18mm FOV. The microscope works with a 0.25A, 250-volt fuse, 8.0A, 250-volt fuse (fuses included), plus a 110-volt source of energy for illumination. It comes having a six-foot power cord.

Microscopes are instruments used to boost the resolution of an object or image. Types include compound, stereo, or digital. Compound microscopes make usage of a compound optical system with the objective lens and an eyepiece. Stereo microscopes show object depth inside a three-dimensional image. Digital microscopes are used to display a picture over a monitor, in lieu of looking by method of a lens. Microscopes may have monocular (one), binocular (two), or trinocular (three) eyepieces, with varying viewing abilities. A trinocular eyepiece is employed to output digital images or video to an inside or external device such as a camera or monitor. Magnification ability refers towards the size associated with an image. Resolution, also called resolvant power, refers towards the clarity in the image. The interaction between field of view (FOV), numerical aperture (NA), and distance (WD) determines resolution. Microscopes can control magnification by strategy for a fixed focus, or by means of a array of adjustments. They can also use LED, fluorescent, and mirror light sources to assist control viewing capabilities. Microscopes are widely used in education, lab research, biology, metallurgy, engineering, chemistry, manufacturing, and inside medical, forensic science, and veterinary industries.
