1IntroductionCCD Instrument TheoreticaliHR 320 Instrument Theoretical and Description Steps of ExperimentsPractical Data discussion Outline2Charge Coupled Device called Image sensor.CCD ( Charge Coupled Device ) due to Can be full record of semiconductor light changes.CCD Main material for silicon semiconductor.Basic principles is similar solar cells.Through the photoelectric effect. To analyze the measured luminous intensity image profile and select the desired area measuring luminous energy density distribution.CCD Introduction3CCD(Ep)(Charge)

analysissoftwareBeam-starCCD CCD ( CCD ) Beam-star3iHR Series spectrometers are automated, triple grating spectrometers available with a 320mm focal 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 Raman Spectroscopy Photoluminescence (near-infrared,NIR)Spectroscopy MicroscopyiHR 320 Introduction 4

:: Fully Imaging Spectrometer: iHR320iHR320 focal length of 0.32m, is designed for an ultra-clear image quality and spectral measurements and design, while the instrument can add up to 20 fibers to realize multi-channel measurement.

Since iHR320 using an asymmetric (Czerny-Turner) Design and The JY company's patented coaxial grating drive system.Thus, making the stray light and the second diffraction is almost reduced to zero.

The parasitic emission at longer wavelength can be explained by a carrier recombination in the p-type AlGaN/AlGaN short-period superlattice due to electron leakage.14Thanks for your attention !15
