Introduction to Reflective Objectives Edmund Optics

WebIn cases where objectives of very low magnification are used in reflected polarized light, a rotatable optical plate (termed an Antiflex cap) consisting of a one-quarter wavelength lambda plate is placed on the objective front lens element to block reflections from the objective itself. The Antiflex method is also particularly useful when the ... Web27. mar 2024 · A Reflecting telescope has either a single or a combination of curved mirrors that is used to reflect the light rays and form an image. On the other hand, a refracting telescope has a lens as its objective lens to form an image. Reflecting telescopes use mirrors whereas the refracting telescopes use lenses. all pro distribution
