The low power objective on a microscope is used to view the specimen under low magnification. It provides a wide field of view, which is useful for examining large specimens or surveying many smaller specimens. The low power objective lens has a magnification power of 10x, and when combined with a 10x eyepiece lens, it provides a total magnification of 100x. This lens is one of the most helpful lenses when it comes to observing and analyzing glass slide samples. The low power objective is also useful for aligning the microscope. It is always safe to use as it cannot be lowered to the point of contacting and possibly breaking a slide. The depth of focus is greatest on the lowest power objective, and each time you switch to a higher power, the depth of focus is reduced. Therefore, the low power objective is a good starting point for focusing on the specimen before switching to higher magnification objectives to observe finer details.
