Reflecting objective lens
WebReflecting telescopes have different options for where the light is brought to a focus. With prime focus, light is detected where it comes to a focus after reflecting from the primary mirror. With Newtonian focus, light is reflected by a small secondary mirror off to one side, where it can be detected (see also Figure 6.5 ). Web8. nov 2000 · The objective lens (in refractors) or primary mirror (in reflectors) collects lots of light from a distant object and brings that light, or image, to a point or focus.; An eyepiece lens takes the bright light from …

The parallel rays enter the tube lens, which forms the specimen image at the plane of the fixed diaphragm opening in the eyepiece (intermediate image plane).
