| *1 |
Prism type binoculars incorporate “normal standing” prisms to correct an image standing on its head to the normal position. There are 2 kinds of normal standing prisms, namely dach prisms and porro prisms: |
| |
・ |
Dach prisms |
: |
the light path is straight, and allows production of slim and compact binoculars. The squareness and acutance of the dach surface affect the binocular performance, and highly advanced precision technique is required to achieve the ultimate accuracy in squareness and acutance. (“dach” means “roof” in Germany.) |
| |
・ |
Porro prisms |
: |
a combination of 2 or 3 rectangular prisms. Every reflection surface produces total reflection, eliminating the need of mirror coating and allowing simple manufacture. The light path is bent in a Z shape, and requires more space. |
| |
| *2 |
Die casting is a technique to press melt metal (aluminum, zinc, etc.) into a precision mold to manufacture a high-precision product. |
