The Olympus CX23 microscope is designed to be used to observe magnified images of specimens in various routine work and research applications, including the observation of living cells or of specimen taken from tissues to gain physiological or morphological information at hospitals or laboratories1. The CX23 microscope has a user-oriented design with an inward-facing rotating nosepiece that enables easier access to the stage, making it easier to change specimens and apply immersion oil if needed.
