How to care for a microscope?

Use both hands when carrying the microscope; one firmly grasping the arm of the microscope, the other beneath the base. Avoid sudden jars. 2. To keep the microscope and lens systems clean: • Never touch the lenses.
Why do microscopes have a blue filter?
Since the limit of resolution decreases at the shorter wavelengths, microscopes are usually fitted with a blue filter. The resolving power of the lens separates the details of the specimen, and the magnification increases the apparent size of these details so that they are visible to the human eye.
