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.

Telescope.
Mirrors and lenses in telescopes bend and focus light to produce an image with more detail.
A Telescope uses lenses or mirrors to collect and focus light from distant objects. With the advancement in optical research we are capable to watch the stars and planets better than before. Our information about universe largely depend on telescopes.
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
