基于平面反射式光栅的微型紫外-可见光谱仪设计 Title:DesignofaMiniatureUltraviolet-VisibleSpectrometerBasedonPlanarReflectiveGrating Abstract: Thedesignofaminiatureultraviolet-visible(UV-Vis)spectrometerplaysanincreasinglyimportantroleinvariousfields,suchasenvironmentalmonitoring,biochemistry,andmaterialscience.Inthispaper,weproposeanoveldesignforacompactUV-Visspectrometerbasedonaplanarreflectivegrating.Thisdesignaimstoovercomethelimitationsoftraditionalbulkyspectrometerswhilemaintaininghighaccuracyandsensitivity.Theuniquepropertiesoftheplanarreflectivegratingprovidesignificantadvantagesinminiaturization,costreduction,andsimplicity.Thevariouscomponentsofthesystem,includingthelightsource,lightmodulation,dispersion,anddetection,arediscussedindetail.Additionally,wepresenttheexperimentalresultsoftheproposedminiatureUV-Visspectrometer,demonstratingitsfeasibilityandpotentialapplications. Introduction: Spectroscopy,thestudyoftheinteractionbetweenmatterandelectromagneticradiation,isafundamentaltoolinscientificresearchandindustry.TraditionalUV-Visspectrometersaretypicallylargeandexpensive,limitingtheirportabilityandwidespreaduse.Toaddressthisissue,thedevelopmentofminiaturizedUV-Visspectrometershasbecomeafocusofresearchinrecentyears.Theutilizationofplanarreflectivegratingsoffersapromisingapproachtodesigncompactandhighlyefficientspectrometers.
