Get PriceReflecting telescope - Gpedia Your Encyclopedia
A reflecting telescope (also called a reflector) is a telescope that uses a single or a combination of curved mirrors that reflect light and form an image.The reflecting telescope was invented in the 17th century by Isaac Newton as an alternative to the refracting telescope which at that time was a design that suffered from severe chromatic aberration.

Custom-made reflectors typically use a high-end mirror that is hand figured by a master optician. Mass-produced reflectors however tend to be of very poor quality. To verify this Stellarvue staff tested a mass-produced 16 f-4.5 mirror from a reflector telescope and found the optical performance to be very poor.

This provides optical stability and simplicity of implementation. A specific design that works well is one where the radius of curvature of the output mirror is 1 m and the distance between the mirror reflective surfaces is 21 cm 29. In this case the optimal input beam radius is about 365 μm at the waist located at the reflective surface of the flat mirror.
