Most are classical great refractors, which used achromatic doublets on an equatorial mount.

reflectors had largely been passed over in favour of small achromats (2 lens refractors).

strong reputation for themselves and there continued a strong interest in refractors for better or worse until the 20th century.

Corporation engineer Roland Christen, the company is noted for its line of apochromatic refractors.

Some other telescope manufacturers use Takahashi refractors as collimating instruments for larger telescopes.

Webb acquired progressively larger refractors and reflectors, the largest was a 9-1/3" (225mm) aperture silver on glass.

next century reflectors had largely been passed over in favour of small achromats (2 lens refractors).

However, other large refractors include a 21st-century solar.

Webb acquired progressively larger refractors and reflectors, the largest was a 9-1/3" (225mm) aperture silver on glass reflector used.

reflectors, refractors with achromatic doublets objective (doublet lens), and apochromatic triplets (after 1760s) objectives.

Great refractors were large refracting telescopes using achromatic lenses (as opposed to.

A derivative instrument of refractors, the heliometer was used to measure for the first.

Telescopes that create their image with an objective that is a convex lens (refractors) are said to be "dioptric" telescopes.
