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 ...

Lasers that transmit data on optical fibers do not produce monochromatic light. Instead, they provide a narrow spectrum that includes many wavelengths. The physical characteristics of optical fibers ...

No other telescope design offers the combination of features and portability as a Schmidt-Cassegrain telescope (SCT). You may not consider it the best for any one application, but it does everything ...

Collimating lenses are used to convert divergent light beams into parallel beams. Collimating lenses are designed for various applications covering from the UV to visible to long wave infrared range.
