The wrench (see figure) has a simple structure, has the characteristics of a plum wrench, and is highly efficient in operation, and can replace ten fixed wrenches, and has outstanding advantages in a large number of disassembly and assembly operations. During operation, pull the handle by hand and push the moving nut to move the clamping nut under the action of its head, tighten or loosen. When the handle is reversed, the wrench automatically opens and the nut is released.
Reflective prisms are used to reflect light, in order to flip, invert, rotate, deviate or displace the light beam. They are typically used to erect the image in binoculars or single-lens reflex cameras – without the prisms the image would be upside down for the user. Many reflective prisms use total internal reflection to achieve high reflectivity.
The most common reflective prisms are:
Porro prism
Porro–Abbe prism
Amici roof prism
Pentaprism and roof pentaprism
Abbe–Koenig prism
Schmidt–Pechan prism
Bauernfeind prism
Dove prism
Retroreflector prism
Beam-splitting prisms
Some reflective prisms are used for splitting a beam into two or more beams:
Beam splitter cube
Dichroic prism
An optical prism is a transparent optical element with flat, polished surfaces that refract light.
