< /center>Structural features of a microscope:
The structure of a microscope mainly includes : Eyepiece, lens tube, converter, objective lens, stage, light aperture, shutter, film clamp, reflector, coarse focus knob, fine focus knob, mirror arm, mirror column and base. When we represent the mirror arms of a microscope, we generally only describe the eyepieces, lens tubes, objective lenses, stages, reflectors, coarse focus knobs, mirror arms, etc. Lets introduce their modeling characteristics respectively. The eyepiece is located at the top of the microscope and is cylindrical in shape. The lens barrel is connected to the eyepiece and is a longer cylindrical body. The objective lens is located below the lens barrel and is connected to it. The stage is located directly below the objective lens, parallel to the cross section of the objective lens, and at a certain distance from the objective lens. Below the stage is a reflector, which is fixed on the stage. There is a circular knob on the top of the lens barrel that connects the lens barrel and the mirror arm, and the bottom of the mirror arm is connected to the frame base to form a complete body.
Simple representation of microscope:
Use simple representation The method of expressing a microscope is generally relatively simple. As long as you master the basic structure and large proportions of a microscope, you can easily draw it. The following is a detailed introduction to the simple method of expressing a microscope.
The simple steps to express a microscope are:
One-step composition and positioning, this step mainly requires the painter to arrange the picture reasonably to make the picture feel more comfortable when people watch it.
The second step is to use lighter long straight lines to express the large external image and main structure of the microscope.
The third step is to draw in detail. In this step, first draw the eyepiece of the microscope, then draw the tube and other parts. The specific drawing method is to first draw a For a short straight line, draw two short lines vertically on both sides of the short straight line, and then draw the part of the lens tube connected to the eyepiece. The lens tube part is drawn as a slender rectangle. Below the lens tube, connectDraw the objective lens. After drawing the objective lens, draw a rough focus knob on the middle and upper part of the lens barrel. After drawing the rough focus knob, draw the lens arm and frame.
After the mirror arm and frame are drawn, add the stage and reflector under the objective lens. At this point, the mirror arm expression of a microscope has been completed.
