The Swedish 1-m Solar Telescope, with a lens diameter of 43 inches, is technically the largest, with 39 inches clear for the aperture.The second largest refracting telescope in the world is the Yerkes Observatory 40 inch (102 cm) refractor, used for astronomical and scientific observation for over a century.
Recent examples of this telescope have sold for well into 5 figures. Today, Tele Vue's apochromatic refractor telescopes, which have reduced chromatic aberration, come in diameters ranging from 60mm (2.4 inches) to 127mm (5 inches). [1] The imaging system ("is" series) telescopes are designed primarily for astrophotography.

Some famous 19th century doublet refractors are the James Lick telescope (91 cm/36 in) and the Greenwich 28 inch refractor (71 cm). An example of an older refractor is the Shuckburgh telescope (dating to the late 1700s). A famous refractor was the "Trophy Telescope", presented at the 1851 Great Exhibition in London.
