Experimental Principles of Fiber Slicing and Microphotography

The experimental principle of fiber slice microphotography is that microphotography is a method of projecting the image from the eyepiece onto the photographic negative, making the negative sensitive and recording the phenomena in the field of vision. In photomicrography, the light emitted by the tiny object W in the film enters the objective lens O, and an enlarged and inverted real image is generated at I 1, which is slightly lower than the focal plane Fe of the eyepiece. The distance between them is d, and the real image is further enlarged by the eyepiece and exits the eyepiece, forming an enlarged real image on the screen, with the position I2. If the screen is ground glass, you can focus on the view, and then change the negative after focusing, and you can shoot.
