Meiji MT4000 Series [MT4300ED] Ergonomic Trinocular Dermatology LED Microscope

Brightfield:
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.

Dermatology:
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 MT4000D Series are used to view thin slices of skin tissue, which have a common setup that utilizes lower magnification objective lenses 4x, 10x, 20x and 40. The lowest magnifications are typically used most frequently. When using a dermatology microscope the samples must be sliced thinly in order to allow the user to view it clearly.

Viewing Heads
Model MA815/05 is the Siedentopf-type binocular head and Model MA816/05 is the trinocular head for camera integration. Each head has the eyetubes inclined at 30° 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. The optional MA957/05, 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 MT4300ED).

Eyepiece
10X Widefield High Eyepoint eyepieces F.N.20 are standard, and 15X and 20X eyepieces are available as an option. A Widefield High Eyepoint 10X focusable eyepiece that accepts 21mm reticules is also available.
