How to make an optical magnifier, how to make a magnifying glass How to make a self made magnifying

Design-Production-Polishing-Polishing-Inspection-Coating-Inspection.

Urgent need?? First of all, the design, now do not consider the achromatic lens (double gluing), only a single magnifying glass, then consider the field of view of the magnifier (controlled by diameter and focal length), shape (mainly meniscus, biconvex, plano-convex type), materials used (ordinary glass, optical glass, resin), etc., to calculate the characteristics of the mold.

Then the mirror embryo is made, and the molten glass is injected into the designed mold to allow the glass to cool to obtain the blank.

The burr is removed by finishing method and the optical surface shape is regularized.

Chemical polishing and cleaning of the optical surface.

The finished product is inspected, and if the lens grade is high, the coating treatment should be carried out, and the lens after coating should be inspected. The quality of the coating directly affects the cost of the lens.

I really don't know the details of this, because I only studied optics, and I haven't done it myself, and I can't afford to add more points, uh, I'm just telling you what I know and think......

If you want to search for technical information, you'd better go to the library to find electronic materials**, the library will generally buy some databases, and there will be them on it, and there will never be these things, which is the truth. When I first finished the design, I didn't know how to use the library, but when I searched, there was nothing, and when I searched the database, it turned out that what I wanted was here!

A Google search may have some too.

Convex lens imaging should be impressive.

Find a thick glass sheet and grind it into a convex lens with thin edges and thick centers.

You can grind it with a grinding wheel, but be careful and safe.

1. Materials required: 1 plastic water cup, 1 syringe, 1 colored pen, 1 scissors, 1 hot melt glue gun.

2. Use scissors to cut the plastic water cup from the middle and divide it into two halves.

3. Draw an equal-sized circle on the water cup divided into two halves with colored pencils, and cut the two circles with scissors.

4. Glue the two plastic sheets together with a hot melt glue gun, leaving a small hole.

5. Use a syringe to inject water into the glued plastic sheet from the small hole, and then seal the small hole with a hot melt glue gun.

6. Write some words on the paper, move the plastic sheet back and forth, and observe whether the shape and size of the words have changed.

Several ways to make your own magnifying glass:

Method 1: 1. Fill a transparent glass with water. 2. Make the ice cubes thick in the middle and thin at the edges.

3. Fill the bag with water and tie the bag tightly.

Method 2: 1, make it with ice, I don't think you need me to say that you know how to do it. 2. Use a bottle filled with water.

3. Make a circle with a small wire and put it in your mouth to get some saliva. 4. Use glass to polish it yourself, but it's very troublesome, and in the end if you want to die with resin, you can also cast it yourself. Noisy.

How to use: Observation method 1: Keep the magnifying glass close to the object to be observed, the object of observation does not move, the distance between the human eye and the object of observation remains unchanged, and then move the hand-held magnifying glass to move back and forth between the object and the human eye until the image is large and clear.

Observation method 2: The magnifying glass is as close as possible to the eyes. The magnifying glass does not move, moving the object until the image is large and clear.

Magnifier: A simple visual optical device used to observe the tiny details of an object, and is a converging lens with a focal length much smaller than the eye's bright-rise group insight distance.

The size of an object imaged on the retina of the human eye is proportional to the angle (angle of view) of the object to the eye.

Summary. Dear, I'm glad to answer for you, how to make a magnifying glass: prepare a pen, cut off the upper part of the plastic bottle, unscrew the cap, and draw a mark on the bottle with a curvature; Cut out the two circles drawn, buckle them together, and glue them together with hot melt glue; Leave a small opening in the disc, squeeze out the air inside, fill it with water, and seal the discs with hot melt adhesive.

Dear, I'm glad to answer for you, how to make a magnifying glass: prepare a pen, cut off the upper part of the plastic source banquet bucket bottle, unscrew the lid, and draw a mark on the bottle with arc; Cut out the two circles drawn, buckle them together, and glue them together with hot melt glue; Leave a small opening in the disc, squeeze out the empty air inside, fill it with water, and seal the discs with hot melt adhesive.

Magnifier definition: magnifier:

Simple Zhikai visual optics used to observe the tiny details of objects are converging lenses with a focal length much smaller than the photopic distance of the eye. [3] The size of the object imaged on the human retina is proportional to the angle of the object to the eye (analogous angle of view).
