अंग्रेज़ी में GALILEAN TELESCOPE का क्या अर्थ होता है?
अवरोधन दूरबीन
एक अपवर्तक या रेफ्रेक्टर दूरबीन ऑप्टिकल टेलीस्कोप का एक प्रकार है जो एक छवि बनाने के उद्देश्य के रूप में एक लेंस का उपयोग करता है। अपवर्तित दूरबीन डिजाइन मूल रूप से जासूस चश्मा और खगोलीय दूरबीनों में इस्तेमाल किया गया था, लेकिन इसका उपयोग लंबे समय तक फ़ोकस कैमरा लेंस के लिए भी किया जाता है। यद्यपि 1 9वीं शताब्दी के उत्तरार्ध में बड़े अपवर्तन दूरबीन बहुत लोकप्रिय थे, लेकिन अधिकांश शोध उद्देश्यों के लिए अपारदर्शी दूरबीन को प्रतिबिंबित दूरबीन ने स्थान दिया है जो बड़े एपर्टर्स को अनुमति देता है। एक रीफ्रैक्टर की बढ़ाई की गणना एपिस की फोकल लम्बाई से ऑप्टिकल ट्यूब की फोकल लंबाई को विभाजित करके की जाती है।
अंग्रेज़ीशब्दकोश में Galilean telescope की परिभाषा
