What microscope part should never be used with the two highest power objectives? condenser fine focus knob stage coarse focus knob diaphragm
Adi S.
A specimen in the microscope has been brought into focus using the 4x objective lens. Once we switch to a higher objective lens, we should only use the fine adjustment knob to adjust the image of the specimen.
Caryl A.
Control the contrast and depth of field of an image. Change the objective from one to another. Control the amount of light from the lamp house. Condense and focus light on the specimen. Correct any difference in vision between the two eyes. Adjust the light intensity of the view field. Condenser. Light intensity level. Rotating nosepiece. Condenser aperture iris diaphragm. Field iris diaphragm. Diopter ring. When viewing a specimen, start focusing with the fine adjustment knob and then fine-tune using the coarse adjustment knob. True False The coarse adjustment knob moves the stage a large visible distance with a single turn, so it should never be used with the 40x and 100x higher power objectives. True False Which of the following are low power objective lenses? 10x. 40x. 100x. All of the above.
