Astronomical Telescope
Product Code : JA-ELA-5330
The Astronomical Telescope (SKU JA-ELA-5330) is a simple teaching model made by JaincoLab that forms an inverted image, as a refracting astronomical telescope does. It uses two lenses in sliding tubes: a 50 mm diameter double convex lens of 500 mm focal length and a plano-convex lens of 38 mm focal length. As an astronomical telescope for optics teaching it lets students focus by sliding one tube inside the other and relate what they see to lens theory.
Specifications
The Astronomical Telescope uses a 50 mm diameter double convex lens of 500 mm focal length and a plano-convex lens of 38 mm focal length, each in a 400 mm tube, with foam plastic rings for smooth sliding focus.

Applications of the astronomical telescope model
The astronomical telescope model is used to show how two convex lenses form a magnified, inverted image of a distant object, and to relate the focal lengths of the lenses to the tube length and the magnifying power studied in ray optics.
- Refracting telescope and ray optics in senior school physics
- Magnifying power of a telescope from the focal lengths of its lenses
- Viewing distant objects in science and astronomy clubs
- Optics demonstrations in B.Sc. physics and teacher training
