• Lead bricks were placed around the radioactive source so that the escaping gamma rays would be limited to a collimated beam rather than filling the lab.
• I need to collimate my telescope so that the images are clearer.
• However, after a bit of experience, the collimating chore can become routine.[...]Of course, if manufacturers made telescopes whose optics did not move around, you would only have to collimate a telescope once.
• Binoculars can be collimated by either eccentric rings on the objective lenses or by tilting the prisms with grub screws (set screws).[...]Always collimate binoculars outdoors, or indoors by looking through an open window.
• When calculating the size of the spot created on the retina by the lens of the eye when focusing the energy from a collimated source, the eye is generally considered to be ideal and diffraction limited.
