High Power Lens Lab Report
To focus a microscope using the high power lens, you have to turn the microscope knob to use the scanning lens. You have to be very careful for this next step; rotate the high powered lens, be sure to do it slowly and do not over turn the knob, if you turn the knob too much, the object you are viewing on the slide might crack, and if it’s a glass on, you can easily get cut.
