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

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

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.
