refractor
Yes. Apochromatic refractors often use 3 lenses in order to focus all visible wavelengths of light at a single point to minimize or eliminate chromatic aberration.
Refracting telescope.
Telescopes use lenses or mirrors to collect and focus light from distant objects. The lenses or mirrors help to magnify the light and form an image that can be viewed by the observer.
Radio telescopes, refracting telescopes, and reflecting telescopes all use mirrors or lenses to collect and focus incoming electromagnetic radiation. The main difference is the wavelength of the radiation they are designed to study – radio telescopes focus on radio waves, refracting telescopes focus on visible light, and reflecting telescopes focus on a variety of wavelengths including visible light, ultraviolet, and infrared.
A refracting telescope uses the most direct light path, relying on lenses (rather than prisms and mirrors) to provide a focused image of the night sky.Its opposite would be the reflecting telescope.
The Hubble Telescope uses both mirrors and lenses to focus on images.
A telescope with achromatic lenses.
the reflecting telescope uses mirrors and lenses. The refracting telescope does not include the mirrors.

The focus is between the two lenses, closer to the eyepiece

Refracting Telescope.
Telescopes use lenses or mirrors to collect and focus light from distant objects. The lenses or mirrors help to magnify the light and form an image that can be viewed by the observer.
A refracting telescope uses two lenses - an objective lens to gather light and focus it and an eyepiece lens to magnify the image.
