The M400 is an entry-level microscope for classrooms and clinics. It uses DIN industry-standard optics, making it compatible with a large selection of objective lenses and eyepieces. All of the necessary functionality is present in an intuitive form factor which is ideally suited for classroom use. The microscope uses a traditional layout which is beneficial for students and other first-time users.
The monocular head keeps things simple. The use of a single eyepiece means that no adjustments are necessary for eye alignment or symmetrical focus. The head can rotate 360° for viewing from different positions. Interchangeable eyepieces allow you to change the overall magnification with optional lenses, or use a camera in place of the eyepiece to view microscopic images on a computer monitor or other display.
The objective turret provides instant access to 3 magnification levels to easily focus in on minute details from 40X to 400X. An additional 16X eyepiece expands the maximum magnification to 640X with 6 unique levels. This covers magnifications needed for studying hair follicles, cells, and some bacteria. These high-quality lenses are achromatically corrected to improve resolution and color accuracy.
The stage is equipped with two clips for holding slides and other specimens in place. The microscope uses independent focus knobs to control coarse and fine adjustments. An adjustable limit-stop mechanism can be used to prevent the lenses from making contact with specimens, preventing damage to the lenses and glass slides.
The microscope is equipped with bright halogen illumination to light the specimen. The sub-stage lamp emits full-spectrum light with a warm color-temperature to limit strain on the eyes. The light is focused using an Abbe condenser, which has an iris-diaphragm to control contrast and focus depth.
