Smooth, continuous iris diaphragm control compatible with newport mounts and positioners Our scopes are parfocal which means that when you switch from low to high power, a focused image. Nikon alphaphot compound light microscope. Contains a system of lenses that directs light from the lamp through the slide specimen. Are made of sturdy materials that help them last for a long time with enhanced durability and sustainability over the years. (13) iris diaphragm controls the amount of light reaching the specimen. A high power or compound microscope achieves higher levels of magnification than a stereo or low power microscope. In my personal microscope, the iris diaphragm is controlled by a little black lever on the side of the condenser, and i push the lever forwards and backwards to change the diameter of the diaphragm.
These microscopes also include a condenser lens and iris diaphragm, which are important for regulating how light hits the. Aligning the microscope for köhler illumination. Oil immersion objectives require maximum light and this is achieved by keeping the iris diaphragm fully open. Opening and closing of iris diaphragm controls the light reaching the object. Look for a lever just under the stage near the front.
