Concentrate light: The objective lens can concentrate the light emitted by distant celestial bodies, causing the light to converge onto the focal plane and obtain a clear image. The curvature and shape of the objective lens determine the focusing ability of light. 2. Improve resolution: The larger the diameter of the objective lens, the more light it can collect, thereby improving the resolution of the telescope. Resolution is the ability of a telescope to distinguish between two approaching objects, and through the magnification and resolution of the objective lens, we can see more details clearly. 3. Achromatic effect: Different colors of light refract differently in the lens, which can cause chromatic aberration, resulting in rainbow colored halos at the edges of the image. Objective lenses can be designed and manufactured to reduce or correct chromatic aberration, enabling telescopes to produce accurate images. 4. Determine the focal length and magnification of the telescope: The focal length of the objective lens affects the observation distance and angle range of the telescope; The magnification of the objective lens determines the size of the observed image. In short, the objective lens of a telescope is an important component in producing clear and accurate images of celestial bodies by focusing light, improving resolution, and eliminating chromatic aberration.
