Collimation aligns a telescope's parts for the sharpest images. Most telescopes need collimation at some point; reflectors need it often. Tools like laser collimators or Chashires help align the ...

Digital imaging and rectangular collimation should be used to ensure that the ALARA (as low as reasonably achievable) principle can be maximized when taking bitewing radiographs in pediatric patients, ...

New collimation measurement instrument for mid-infrared wavelengths. This instrument is for the testing of lasers and optics in the mid-infrared (3-5µm), which are used in imaging and remote sensing ...
