Meiji Techno's laboratory grade upright microscope line is the new and cost-effective MT5000 Series Biological Microscopes. The MT5000 Series employs all new and improved U.Plan optics. Meiji Techno's ICOS™ (Infinity Corrected Optical System) makes the study of mounted specimens fast and easy while delivering an excellent cost-to-performance ratio. The demand for a reliable Dermatology Microscope has been growing in popularity, with new treatments for skin cancer are appearing and evolving rapidly in recent years. However, one surgical technique has more than stood the test of time. Developed by Dr. Frederick Mohs in the 1930s, Mohs micrographic surgery has, with a few refinements, come to be embraced over the past decade by an increasing number of surgeons for an ever-widening variety of skin cancers. Mohs specialist are in demand of a microscope that will help them identify cancer at every stage of growth. Mohs surgery has come to be accepted as the single most effective technique for removing Basal Cell Carcinomas (BCC) and Squamous Cell Carcinomas(SCCs), the two most common skin cancers. It accomplishes the nifty trick of sparing the greatest amount of healthy tissue while also most completely expunging cancer cells; cure rates for BCC and SCC are an unparalleled 98 percent or higher with Mohs, significantly better than the rates for standard excision or any other accepted method. The reason for the technique's success is its simple. Mohs differs from other techniques in that microscopic examination of all excised tissues occurs during rather than after the surgery, thereby eliminating the need to "estimate" how far out or deep the roots of the skin cancer go. This allows the Mohs surgeon to remove all of the cancer cells while sparing as much normal tissue as possible. The procedure entails removing one thin layer of tissue at a time; as each layer is removed, its margins are studied under a microscope for the presence of cancer cells. If the margins are cancer-free, the surgery is ended. If not, more tissue is removed from the margin where the cancer cells were found, and the procedure is repeated until all the margins of the final tissue sample examined are clear of cancer. In this way, Mohs surgery eliminates the guesswork in skin cancer removal, producing the best therapeutic and cosmetic results. In the past, Mohs was rarely chosen for Melanoma surgery for fear that some microscopic melanoma cells might be missed and end up spreading around the body (metastasizing). However, efforts to improve the Mohs surgeon's ability to identify melanoma cells have led to special stains that highlight these cells, making them much easier to see under the microscope. Thus, more Mohs surgeons are now using this procedure with certain melanomas. With the rates for melanoma and other skin cancers continuing to increase, Mohs will play an ever more important role in the coming decades. The MT5000D Series is a useful tool in helping bridge the gap in helping find a cure to this curable cancer.

The simplest of all the optical microscopy illumination techniques. Sample illumination is transmitted (i.e., illuminated from below and observed from above) white light and contrast in the sample is caused by absorbance of some of the transmitted light in dense areas of the sample. Brightfield microscopy is the simplest of a range of techniques used for illumination of samples in light microscopes and its simplicity makes it a popular technique. The typical appearance of a brightfield microscopy image is a dark sample on a bright background.
The demand for a reliable Dermatology Microscope has been growing in popularity, with new treatments for skin cancer are appearing and evolving rapidly in recent years. Mohs surgery, also known as chemosurgery, is the most commonly used in the study with dermatology. Mohs surgery has come to be accepted as the single most effective technique for removing Basal Cell Carcinomas (BCC) and Squamous Cell Carcinomas(SCCs), the two most common skin cancers. It accomplishes the nifty trick of sparing the greatest amount of healthy tissue while also most completely expunging cancer cells; cure rates for BCC and SCC are an unparalleled 98 percent or higher with Mohs, significantly better than the rates for standard excision or any other accepted method.
The MT5000D Series are used to view prepared thin slices of thin tissue, which have a common setup that utilizes lower magnification objective lenses 4X, 10X, 20X and 40X. The lowest magnifications are typically used most frequently. When using a dermatology microscope the samples must be sliced thinly in order to allow the physician to view it clearly.
Model MA815 is the Siedentopf-type binocular head and Model MA816 is the trinocular head for camera integration. Each head has the eyetubes inclined at 30 degrees with the left eyetube having graduated diopter settings. The interpupillary distance is adjustable between 53mm - 75mm. An 80/20 beamsplitter for the trinocular tube can be engaged for photo work. (100% to eyetubes or 80% to phototube & 20% to the eyetube.) The optional MA957, Ergonomic Binocular Viewing Head, has the inclination adjustable from 10 to 50 degrees to fit users of different heights. The Ergonomic Trinocular model comes with the MA958, photo/video attachment with sliding 80/20 beam-splitter (Included in MT5300ED).
10X Super Widefield High Eyepoint eyepieces F.N.22 are standard, and 15X and 20X eyepieces are available as an option. A Super Widefield High Eyepoint 10X focusable eyepiece that accepts 25mm reticules is also available.
