Pyramid Prism

The pyramid is also a polyhedron, with a polygonal base and a point (called the apex) connected by triangles extending from the edges. A pyramid has only one apex, but the number of vertices is dependent on polygonal base.

High Precision Alignment Cube

Alignment cubes are used to monitor and qualify systems where critical optical alignment is necessary. Precision Optical offers standard and custom sized optical alignment prisms with precision angles in several glass types. For extreme temperature applications, materials such as Zerodur (LaserStates Code LAS) and fused silica are optimal choices due to their low thermal expansion coefficients.
