Corner cube Prism is also named retroreflector or trihedral prism.In the corner cube prism,three reflecting surfaces are perpendicular to each other,like the side wall of the cube.The input surface is perpendicular to the cube diagonal. Disregarding the anlge of the incidence,the output beam is parallel to the input one,but it is of opposite direction. Inset of the several corner prisms, for better matching,their extrance exit surface is often hexagonal.In case of this prism the phenomenon of full internal reflection occurs so it is not necessary,(however it is possible)to put mirror coating on the reflecting faces. Normally the reflection surfaces are AL reflection coating, and then covered with Cu and Black painting.
Pyramid prism/Corner Cube Retroreflector is always used to reflect the beam entering the prism face, regardless of its orientation to the beam. Corner cubes are widely used where precision alignment is difficult.

Separation of special materials on the centrifuge experimental technical requirements
Centrifuges are widely used in biomedicine, petrochemicals, agriculture, food hygiene and other fields, it uses the difference in sedimentation speed of different materials in the centrifugal force field, to achieve the separation of the sample analysis. This paper centrifuge separation of some volatile and other special materials should pay attention to the problem, to be summarized, I hope the majority of users of centrifuges helpful. Some special properties of the material to be separated during the centrifuge separation and some special requirements for the products obtained from the separation must be taken into account when choosing the type of centrifuge. As follows: 1 is the separation of materials, either solid or liquid phase, if the valuable material, the requirements of high recovery. 2. Separation of corrosive materials, the choice of mechanical materials have special requirements. 3. Separation liquid phase is volatile or easily cause explosive and flammable materials, can not be vacuum filtered, and require sealed explosion. 4. Separation of solid-phase material for the crystalline product, the degree of damage required to separate crystallization is low. This separation of the mechanical structure and discharge methods, methods have special requirements. 5. Separation of solid particles larger hardness, the requirements of the selected centrifugal material wear resistance.
