Glossary term: दूरदर्शक दुर्बीण (टेलिस्कोप)

Description: टेलिस्कोप हे एक असे उपकरण आहे जे दूरच्या वस्तूंमधून फोटॉन (दृश्यमान प्रकाश किंवा इतर तरंगलांबीचे) गोळा करते आणि त्यांच्याबद्दल माहिती (उदा. प्रतिमा) निरीक्षकाला पुरवते. सुरुवातीच्या दुर्बिणीत (१७व्या शतकाच्या सुरुवातीपासून) भिंग हे ऑप्टिकल घटक म्हणून वापरले जात होते (अपवर्तक दुर्बिणी पहा). भिंग किती मोठ्या प्रमाणात बनवता येतील यानुसार मर्यादित असतात, त्यामुळे मोठ्या दुर्बिणीचा वापर करून अधिक तपशीलाने क्षीण खगोलीय वस्तू पाहण्यासाठी, भिंगांऐवजी प्रकाशाला केंद्रित करण्यासाठी आरसे (परावर्तित दुर्बिणी पहा) वापरण्यात आले. सर्वात मोठ्या ऑप्टिकल टेलिस्कोप परावर्तित दुर्बिणी आहेत. 20 व्या शतकात, इलेक्ट्रोमॅग्नेटिक रेडिएशनच्या इतर क्षेत्रांचा अभ्यास करण्यासाठी दुर्बिणींचा शोध लावला गेला, त्यामुळे आता रेडिओ दुर्बिणी, इन्फ्रारेड दुर्बिणी, क्ष-किरण दुर्बिणी इ. अस्तित्त्वात आहेत. खगोलीय स्त्रोत क्षीण असतात, त्यामुळे खगोलशास्त्रज्ञ अधिक प्रकाश गोळा करण्यासाठी मोठ्या दुर्बिणीचा तयार करतात आणि बारीक टोकदार रिझोल्यूशन गाठतात.
