The cold finger reservoir needs to be has to be crammed with liquid nitrogen before the microscope is applied. Contaminants sometimes lead to a phenomenon often called drift. Drift will be the evident "motion" from the specimen over the monitor. It's due to poor Call in between the grid as well as the specimen holder resulting in a buildup of heat and static charges. An objective aperture is utilised to improve specimen distinction. Intermediate lenses magnify the picture coming from the target lens. Eventually, projector lenses further more Amplify the graphic coming within the intermediate lens and projects it on for the phosphorescent display.
Dưới đây là một số mẫu tem decal trong suốt đẹp, được ưa chuộng bạn có thể tham khảo:
