The Van Guard 1493INI inverted microscope includes a trinocular viewing configuration, phase contrast illumination, plan achromatic, infinity objectives, multiple stage inserts, and magnification abilities of 4X, 10X, 20X, and 40X, to get a selection of applications. This microscope enhances object or image resolution, and it is commonly employed for observation of biological cultures or specimens within well plates, petri dishes, or vials in areas that demand a longer working distance, in university research settings and in medical and industrial laboratories

This microscope comes with a trinocular viewing configuration, with two eyepieces to ease eye strain and offer a far more comprehensive view, and a third visit connect to an external monitor or camera with an alternative viewing option. The binocular viewing heads have rubber eyecups to bar out external light interference, are fixed vertically at 30 degrees, and rotate 360 degrees. The microscope features a 20/80 light split, meaning that when 1 / 3 head is used, 20% of the light goes from the third head, and 80% goes for the user’s eyes with the binocular heads. The unit has 48-75 mm interpupillary adjustment for individual eye spacing, and - 6 to + 6 dioptric adjustment capabilities to make up to the difference in viewing ability in between each eye. It features a VanGuard infinity-corrected optical system (VIOS) for clear images. Adjustable rotation provides Deutsches Institut für Normung (DIN)-standard resolvant options of 4X, 10X, 20X, and 40X (0.10, 0.25, 0.40, and 0.60 numerical aperture [NA]). Plan achromatic objective lenses correct for red and yellow chromatic aberrations and sharpen images. Phase contrast illumination produces clearer images of opaque or unstained objects, as well as an iris diaphragm controls light diameter. The unit features a 0.30 numerical aperture (NA) Abbe condenser for higher resolution, with phase slider annuli for 10X, 20X Stop, 40X Stop, and filter stop. It has an open setting for brightfield, along with a telescoping eyepiece for phase annuli centering. The condenser is mounted over a rack and pinion focusing mechanism, features spring-loaded centering knobs, and has an inward swinging filter holder. The unit includes a 30-watt variable quartz halogen illumination with front insert and phase slider. The unit includes a 10X ultra widefield eyepiece magnifier, which locks on towards the unit for ease of operation, and supplies a 22 mm field diameter. The unit has high-eyepoint eyepieces which can be 400 mm high, and have a very focal depth (FD) of 22 mm.

The microscope includes a rectangular, chemical-resistant, mechanical stage with rack and pinion assembly plus a long X-Y, right-hand, drop-down control for maneuverability. You will find two auxiliary stages. A circular, glass insert area works having a variety of stage inserts, including those accustomed to support plates dishes, vials, and slides. Examples include 96-well plates, HLA/Teraski plates, 3” x 1” glass slides, and 65 mm, 54 mm, and 35 mm petri dishes. The stage includes a cross travel variety of 120 x 80 mm. Stage dimensions are 250 x 160 mm (W x D), plus a drop-down, right-hand, coaxial mechanism controls motion. It has coaxial, ultra-low position, coarse- and fine-focus adjustment controls having a 40 mm focusing range, that graduate to two microns per division. Auto-stop and tension control mechanisms protect the gears. The reversed-pitch (inward facing) nosepiece has five rotation positions to support a array of magnification. Sample clearance is 75mm, or could be adjusted to 150 mm once the condenser is removed. The microscope features a stain-resistant and durable cast metal body with the enamel finish, and anti-skid rubber feet. Referring which has a clear diffusing filter, blue and green filters, an additional lamp and fuse, a telescoping eyepiece, a dust cover, and instructions. The 1493INI has five-year mechanical and optical warranties, as well as a one-year electrical warranty.

The 1493INI microscope overall dimensions are 475 x 250 x 515 mm (H x W x D) , and base dimensions are 240 x 320 mm (W x D) . The unit weighs 8.7 kg. Plan achromatic objective specifications are: 4X: 0.10 NA, 25.2mm working distance (WD); Plan achromatic phase specifications are: 10X: (0.25 NA, 11mm WD); 20X: 0.25 NA, 6mm WD; 40X: 0.60 NA 3.2 mm WD. It works using a 0.50A, 250-volt fuse (included), as well as a 110-volt power source for illumination, and comes with a six-foot power cord.

Microscopes are instruments utilized to enhance the resolution associated with an object or image. Types include compound, stereo, or digital. Compound microscopes work with a compound optical system having an objective lens as well as an eyepiece. Stereo microscopes show object depth in a three-dimensional image. Digital microscopes are accustomed to display an image on a monitor, in lieu of looking by having a lens. Microscopes might have monocular (one), binocular (two), or trinocular (three) eyepieces, with varying viewing abilities. A trinocular eyepiece is used to output digital images to an inside or external device such as being a camera or monitor. Magnification ability refers to the size associated with an image. Resolution, also known as resolvant power, refers to the clarity in the image. The interaction between field of view (FOV), numerical aperture (NA), and working distance (WD) determines resolution. Microscopes can control magnification by having a fixed focus, or by having a selection of adjustments. They can also use LED, fluorescent, and mirror light sources to aid control viewing capabilities. Microscopes are widely found in education, lab research, biology, metallurgy, engineering, chemistry, manufacturing, and inside medical, forensic science, and veterinary industries.
