Perfect for the budding biologist, the Celestron 4050 biological microscope gives you the power and control to study samples with depth and clarity. This monocular unit is inclined at 45 degrees. A 360-degree rotatable head and positive-click nosepiece with three objectives (4x, 10x, 40x) round out the optical portion of the scope. Electrical illumination and a metal 110mm by 120mm stage with a five-aperture diaphragm complete the package.
