This phenomenon is called . if the emission takes place very shortly after the absorption of light; it is called . or . where the emission is significantly delayed. All these phenomena, taken together, are called .. To generate luminescence an external energy source, for instance a lamp, is necessary.运动性 发表于 2025-3-25 09:57:20

The light microscope as a tool for observation and measurement: illumination and image formation,When a light wave strikes an object, different kinds of interaction may take place, resulting in a modulation of the illuminating rays. These interactions may be a factor in image formation, but they can also be a disturbing element.Musculoskeletal 发表于 2025-3-25 18:00:49
Viszeral- und Transplantationschirurgier or by other means. In all these cases, the same optical laws apply. These laws will be dealt with briefly in this first chapter since they provide the foundation for the construction and the functioning of the microscope. The long and continuing development of the microscope has been the result ofDefraud 发表于 2025-3-25 21:00:11

H. Kreienfeld,H. Klimpel,V. Böttcherssed in Section 2.1) which, unlike the case of amplitude changes, are not revealed in the visible image. Consequently, a transparent object such as a tissue section will give an image which is poor in contrast and yields little information. By reducing the aperture of the illumination beam by means重力 发表于 2025-3-26 07:58:32

The drawing of microscopic images remained a means of communication long after photography came into more general use around 1900. For a long time, pquiet-sleep 发表于 2025-3-26 09:14:34
