Olympus-IX81- Wide-field microscope
The Olympus IX81 is a fully automated inverted microscope - objectives are below the stage. This microscope is ideal for 2D and 3D imaging of fixed and live specimens. Excitation and emission filter wheels enable fast time-lapse imaging. The microscope is equipped with a temperature-controlled chamber for imaging living cells.
A stereology application is available on the IX81. Stereological techniques are performed to estimate the total number, volume, and surface area of objects in a biological structure. For instance, stereology uses random and unbiased sampling of tissue sections to extrapolate the total number of cells in a 3D structure.
A color camera is also available for histochemical and immunohistochemical staining.
