Katadioptrilised
Katadioptrilised refers to a class of optical instruments that use a combination of lenses and mirrors to form an image. The term "katadioptrilised" is derived from the Greek words "kata" (down) and "dioptron" (through-sight), indicating a system that works by both reflecting and refracting light. These instruments are designed to overcome some of the limitations of purely refractive or purely reflective systems.
The primary advantage of katadioptrilised designs lies in their ability to achieve long focal lengths within
Examples of katadioptrilised instruments include the Schmidt-Cassegrain telescope and the Maksutov-Cassegrain telescope. These telescopes are popular
