WebMay 31, 2024 · Photomacrography is extremely sensitive to small movements and vibration of the camera equipment and subject. Very solid supports and a very precise focusing rack are indispensable. Intense illumination of the subject is usually indispensable to focus accurately, and exposure times are typically long without a flash. WebThis process is defined as the attachment of a coverslip (cover glass) on to the slide using a mounting medium. Coverslips vary in size and thickness. The coverslips with a thickness of 180 μm provide an ideal range for photomicrography. The size depends on the size of the area to be covered.

WebDOF versus numerical aperture. It is the nature of focus definition that the numerical figures have greater tolerances and so for 10 X lenses a DOF of ~ 3-6 µm and for 20 x lenses a DOF of ~ 2-4 µm can be assumed. Based on such weak figures only an approximate step size can be derived. If 5 µm steps are used and the target DOF ist 300 µm ...
