The biconvex lens is a biconvex lens sheet, which comprises an incident surface and an emitting surface. It is characterized in that the focal length of the middle part of the lens surface is long and the focal length of the end of each transparent mirror is short. Biconvex lens is mainly used to gather light from point light source or transmit images to other optical systems.
Biconvex lens introduction
The biconvex lens is a biconvex lens sheet, which comprises an incident surface and an emitting surface. It is characterized in that the focal length of the middle part of the lens surface is long and the focal length of the end of each transparent mirror is short. Biconvex lens is mainly used to gather light from point light source or transmit images to other optical systems.
Biconvex lens structure
The lenticular structure is on the image, which is called a cylindrical image. The thin and slender surface semi cylindrical convex lens is arranged in countless pieces (biconvex lens). The sheet is made of transparent plastic. It is made by pasting paper on the printing material printed with image or printing image directly on the back of the paper. In a lenticular image, two or more images are cut into thin strips, and the cut images are arranged in interlaced order to form a single image. You must paste (or print) to place a convex lens on each strip of the image. If the position is offset, it cannot be seen clearly. In a 3D display, pixel lines and lenticular lines are matched to display different images in every other line.
Example of biconvex lens
The following three types of effects can be obtained through a biconvex lens.
The pattern varies according to the viewing angle. Combine completely different images.
Something with animation. Combine many different images. You can watch videos while moving.
Something with a 3D effect. Combine the two parallax images of the left eye and the right eye together (stereo pair). Unlike the above two, you can get a three-dimensional effect from one point rather than moving your eyes.
