Accessories used to upgrade ordinary transmitted light upright microscopes to reflected light, supporting up to 50X objective lenses (to obtain high-quality images, the objective lens also needs to be replaced with a reflected light objective lens. Our company has MPlan5X, MPlan10X, MPlan20X, MPlan50X, and MPlan100X to choose from), and an orthogonal polarization module can be added to achieve partial polarization observation function.
