Charge Coupled Device(CCD) Professor： Kuen-Hsien Wu Reporter：Ching-Hua Chen Outline Introduction CCD Instrument Theoretical iHR 320 Instrument Theoretical and Description Steps of Experiments Practical Data discussion 2 CCD Introduction Charge Coupled Device called Image sensor. 影像感測器 CCD ( Charge Coupled Device ) due to Can be full record of semiconductor light changes. 可記錄光線變化的半導體所組成 CCD Main 主要材質為矽晶半導體 material for silicon semiconductor.Basic principles is 基本原理類似太陽能電池 similar solar cells.Through the photoelectric effect. 透過光電效應 To analyze the measured luminous intensity image profile and 分析所量測到的發光強度影像分布圖 select the desired area measuring luminous energy density 以及選取所要量測發光能量密度分布的區域 distribution. 光信號 analysis software： Beam-star 光子 (Ep) 電信號 電荷 (Charge) 3 iHR 320 Introduction iHR Series spectrometers are automated, triple grating spectrometers 三倍光柵光譜儀 available with a 320mm focal焦距length or a 550 nm focal length. Designed for multi-channel CCD spectroscopy, these spectrometers are ideal for a variety of research applications, including: • Fluorescence 螢光 • Raman Spectroscopy 拉曼光譜 • Photoluminescence • (near-infrared,NIR)Spectroscopy 近紅外光 • Microscopy 顯微鏡 中文名稱:光譜儀 英文名稱: Fully Imaging Spectrometer 產牌型號: iHR320 4 iHR 320 Introduction iHR320 focal length of 0.32m, is designed for an ultra-clear image iHR320的焦距為0.32m,是專為獲得超清晰質量圖像 quality and spectral measurements and design, while the instrument 及其光譜測量而設計的,同時儀器可外接多達20根光纖,實現多通道測量。 can add up to 20 fibers to realize multi-channel measurement. 由於iHR320採用了一個非對稱車爾尼特納（Czerny-Turner)設計 Since iHR320 using an asymmetric (Czerny-Turner) Design and The JY company's patented coaxial grating drive system.Thus, 和JY公司獲得專利的共軸光柵驅動系統,因此使得雜散光和二次衍射幾乎降低為零。 making the stray light and the second diffraction is almost reduced to zero. iHR320 Dual Exit and Entrance Port Operation(for example： 同時, iHR320配有兩個輸入端口和兩個輸出端口。每一個輸出端口既可以選擇使用陣列檢測器, CCD,slit,photomultiplier) 如：CCD,也可以使用狹縫和光電倍增管。 5 Description 6 iHR 320 Description 7 iHR 320 Description 8 Steps of Experiments 9 Steps of Experiments 10 Steps of Experiments 11 Practical Data discussion SIGNAL_1_cycle1 60000 55000 50000 Intensity (Counts) 45000 40000 35000 30000 25000 20000 15000 10000 5000 0 -5000 200 400 600 800 1000 Wavelength (nm) 12 Practical Data discussion SIGNAL_1_cycle1 SIGNAL_1_cycle2 SIGNAL_1_cycle3 55000 50000 45000 Intensity (Counts) 40000 35000 30000 25000 20000 15000 10000 5000 0 -5000 200 400 600 800 1000 Wavelength (nm) 13 Practical Data discussion 14 Thanks for your attention ! 15
