prism

the prism of science.

A prism disperses light.

The prelude was as iridescent as a prism in a morning room.

The prism broke the light into all the colors of the rainbow.

The analytical study on transmitted intensity′s perturbance of the Glan-Taylor prism with varying rotation angle is given.

By reducing the tangential representation set of small covers over prisms to a prime form,this article determines the classification of small covers over prisms up to equivariant cobordism.

Instead of the solid block of glass of the prism in pentaprism system, here 3 simple mirrors are used to perform the same task.

Using phasemeter, the two prisms can be moved out off the beam, so the system can be used to measure coaxality.

When the lens is in focus, the rays coincide at the plane of the focusing screen, and objects see through the prisms appear "unsplit.

The wavelength division effect of grism in a multi-wavelengths optical system is discussed, the grism consist of a tranditional optical prism and a diffraction optical phase grating.
