collimate

Dr. Donald Frush, chief of pediatric radiology at the Duke University School of Medicine, said that failing to properly cone, or collimate, the radiation was rare.

The collimated outflow produces the radio waves, while the disk of gas surrounding the black hole emits X-rays.

However, Sgr A* currently has limited nearby matter, so the black hole has been relatively quiet, with weakly collimated outflows, in recent millennia.

The result is an intense beam of collimated, or parallel, rays of electromagnetic radiation.

A bright white light under water is collimated and directed upon a prism.

The γ rays are collimated in such a manner that only 1.00% of them strike the patient.

The collimating lens L₂ is filled by this beam, and the rays issue parallel to one another and fall on the prisms P₁ and P₂, which disperse them.

If the source be a point or a line, and a collimating lens be used, the incident waves may be regarded as plane.

One slit is a little below the other, the rays being reflected to the collimating lens L, by means of two right-angled prisms P, and two spectra are formed, one above the other.

From Colour Measurement and Mixture by W. de W. Abney

I took out the little collimating screws first, then I drew out the tube, and in that I found a brass plate screwed on the diaphragm which contained the lines.

From Maria Mitchell: Life, Letters, and Journals by Maria Mitchell

Light which enters the collimating lens partly passes through the prisms and is partly reflected from the first surface of the prism; that we utilize, thus giving a second shadow.
