Les réflecteurs se servent de miroirs au lieu de lentilles pour refléter la lumière sur un foyer : le miroir primaire à l'arrière, gros et incurvé, qui effectue la première focalisation, et le miroir secondaire à l'avant, plus petit, conçu pour rediriger la lumière vers l'œil. Les réflecteurs sont également dotés d'un oculaire. 3, record 1, French, - t%C3%A9lescope
