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.

As the black hole spins, matter can escape in the form of narrow jets called collimated outflows.

From Science Daily ● Feb. 21, 2024

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

Alternatively, the low-luminosity γ-ray transient may not trace the prompt GRB emission, but come from a broader collimated, mildly relativistic cocoon29.

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.

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.

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.

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.

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

From Encyclopaedia Britannica, 11th Edition, Volume 8, Slice 4 "Diameter" to "Dinarchus" by Various

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.
