The prisms cleave, though imperfectly, at right angles to the geometrical axis; and hexagonal slices were formerly worn in the East.

The primary form of the crystals is a right rhomboidal prism.

Each of these two equal parts is a right tri-prism.
"Text books of Art Education, v. 2 of 7" by Hugo B. Froehlich
The usual form of ice-crystals in clouds is a right hexagonal prism, which may be elongated as a needle or foreshortened like a thin plate.

Moreover, we get the function RR Da at the tope face and the function RR La at the right face of the prism (speci´Čücally, the restriction of this function to this triangle).
Arrays and the octahedron recurrence
Its dual is the triangular prism (Figure 3, right), which is a non-simplicial polytope of dimension d = 3 with precisely one pair of disjoint facets (the triangles at the top and bottom, shaded in the diagram).
Complementary vertices and adjacency testing in polytopes
The 2 polarizers are identical, they are designed as Glan-Thompson prisms: made of two right-angled Calcite prisms cemented together2 .
Design of the wavefront sensor unit of ARGOS, the LBT laser guide star system
The collimated beam from the Brashear spectrograph enters from below through the hole on the lower left, passes through the prism (visible under the large triangular plate), and proceeds to the f /2.5 Voigtlander lens that is mounted inside the large brass cylinder in the upper right.
