The parfocal distance is 45 mm. When using a 10\/22 mm eyepiece, the field of view diameter is 0.55 mm. The objective is designed for use with samples with 0.17 mm coverslips.\u003c\/p\u003e\u003cp\u003eThe lower limit of the useful microscope magnification, when using a 40x objective, is 325x. A lower magnification does not allow distinguishing the details of the sample whose image is formed by the objective.\u003cbr\u003eThe upper limit of the useful magnification, when using a 40x objective, is 650x. Higher magnifications are considered \"empty\" as they do not provide any new details in the sample image. \u003cbr\u003eWhen using a 40x\/0.65 objective, use 10x–15x eyepieces to take advantage of the useful magnification of the microscope.\u003c\/p\u003e\u003cp\u003ePlan achromatic objectives form an image that is equally in focus at the center and edges, thus distortion is negligible.
