Practically all telescopes which use lenses, normally the refracting type. the Reflector use objective Concave Mirrors, but even these need eyepieces or finder scopes.

The refractor telescope is the instrument that uses a lens or system of lenses to bend light and form an image on a focal plane.

What type of instrument uses an objective lens and an eyepiece lens?
Microscope.
What telescope with 2 lenses called?
A refracting telescope uses lenses. The primary objective is the larger lens and the first point of light refraction. A smaller, secondary lens is located between the primary lens and the eyepiece as acts as another refraction device to correct or reverse the refractive aberration of the primary.
What is the difference between a refracting telescope and a?
A refracting or refractor telescope is a dioptric telescope that uses a lens as its objective to form an image. The refracting telescope design was originally used in spy glasses and astronomical telescopes but is also used in other devices such as binoculars and long or telephoto camera lenses.There are two basic types of telescopes, refractors and reflectors. The part of the telescope that gathers the light, called the objective, determines the type of telescope. A refractor telescope uses a glass lens as its objective. The glass lens is at the front of the telescope and light is bent (refracted) as it passes through the lens. A reflectortelescope uses a mirror as its objective. The mirror is close to the rear of the telescope and light is bounced off (reflected) as it strikes the mirror
How is the image projected through a telescope?
The main lens or mirror produces a virtual image of the obect being looked at, and it occurs at a distance behind the lens (or in front of the mirror) equal to the focal length. The telescope also has an eyepiece whose function is to allow the oberver to see the virtual image. Many telescopes come with a range of different eyepieces that give different amounts of magnification.
Which part of a refracting telescope forms the image?
Eyepiece, Primary Mirror, Secondary Mirror, Prime Focus.

How does a refracting telescope differ from other types of telescopes?
A refracting telescope is a type of telescope that uses a lens as its objective to form an image. This is different from other type of telescopes because it has a objective lens.

Does a telescope use a convex lens?
Reflecting telescopes don't use lenses - they use mirrors (hence 'reflecting'). Light goes in the top, hits a concave mirror at the bottom of the tube which makes the light converge when it is reflected, then bounces back up to the top where it hits a smaller secondary mirror, where it is directed down the eyepiece. Do you mean refracting telescopes? If so then these do use lenses, the amount depends on the telescope. The most simple form has an objective lens which focuses the light, and then an eyepiece which has a lens in it to magnify the image. The objective lens is convex on the side pointing out of the telescope, and is flat on the other side.

What type of lens does a reflecting telescope use?
A reflecting telescope only uses lenses in the eyepiece. Light is picked up and an image produced by using a concave parabolic mirror.

What is a telescope that uses a mirror to collect light emitted by distant or faint objects?
This type of telescope is often referred to as a Schmidt-Cassegrain telescope, and can be short and wide. They have an eyepiece that extends at a right angle from the body, and have a disk in the middle of the lens, behind which is the mirror.
What uses a lens and two mirrors?
Reflecting TelescopeA reflecting telescope uses a lens and two mirrors. The lens is positioned at the eyepiece, and thus the focus, which the two mirrors generated by specifically redirected light. There are two types of reflecting telescopes with one lens and two mirrors, the Newtonian Focus and the Cassegrain Focus.
